After the post-Iraq invasion Iran saw the security void as an opportunity to reshape Iraq in order to prevent it from re-emerging as a strategic threat, although its operation of Iraq’s freedom resulted to high levels of insecurity mainly because other countries failed to see Iraq as a regionally powerful country. Iran’s foreign policy aims and roots are not only mainly pragmatic; they are defensive and based on state-orientated strategic issues. The research continues to broadly discuss Iran’s Foreign policy through the following heading which is Iran’s foreign policy principles, Iran’s first revolution, the second revolution, approaches of the Islamic Revolution, Iran’s foreign policy in the light of the Arab revolts and lastly Iran’s foreign policy towards United States.

RADIO Radio is a fascinating medium among the various mass communication media because of its special characteristics. It continues to be as relevant and potent as it was in the early years despite the emergence of more glamorous media. It is a saying that in the first phase of broadcasting spanning three decades from the early twenties, radio reigned alone or was the dominant player. Similarity, radio is a scientific device that functions as an effective auditory instrument for communication. It also plays an important role in education. It is not only informs, but also inspires human being for learning more and more. It is not only includes values and virtues, but also creates attitudes, interests and appreciation of human life. It can cover a very wide area at the same time. Radio has immense values, particularly in a developing country like India where constraints of finance, efficient teachers, suitable equipment and appliances adversely affect educational planning and administration. Besides that, radio is to play a significant part in expansion as well as qualitative improvement of education. There are some inaccessible areas in our country where expansion of education has faced difficulties. To a large number of socially disadvantaged children, education is neither meaningful nor interesting. Radio served hugely the human instinct to know about events taking place around him and at distant lands. No fairy tales, but the radio brought news from across the oceans and from inland without distinction. A regular listener of radio news would get an impression as the whole world has shrunk a feeling which print media would never had thought in around 400 years before the invention of the radio. Besdies, the news aired regularly from different stations were followed by views and a much spicy discussion mong experts to generate more interest in events from social and political life. The announcements about weather, and trains or flights schedule has been an added advantage to radio listeners. There has been a growing awareness about the inadequacy of the traditional or formal system of education not only for expansion, but also for improving the standards of education. The need f or alternative mass-media is gradually felt along- with non-formal system of education. It is a matter of fact that radio is an important instrument to foster the sense of unity and integrity among the people. The cultural programmes, debates, talks, through broadcasts involve a strong desire among the people to know each and other’s culture and values. In order to promote a sense of understanding and unity among people it is an inexpensive, but potential communication medium reaching all levels of people. So its role for national/emotional integration and international understanding is praise-worthy. Entertainment is an important aspect of human life. Radio is the most popular mass medium through which leisure is carefully utilized through song, drama and other cultural, programmes. It also provides information about various popular hobbies and leisure time activities. It gives happiness and joy through various programme. As already mentioned, radio brought a unique entertainment opportunities to people, especially for those who could not afford the luxury of visiting places where entertainment was available only to the rich. With a radio set by their side, common people could also enjoy music and stayed informed about events as ordinary as a street robbery to change of governments and tug of war among political rivals to availability of commodities in the market. But it was the entertainment which made the radio popular on first instance. Very soon the entertainment started moving in other areas than music. Comedy shows, gossip chat and answering letters from listeners made people crazy about radio enjoyments. Vocational information about production and consumption practices in industry and agriculture, use of manures and highbred seed, employment news are broadcast by Radio. Programmes regarding self-employment and talks by skilled people ensure better understanding among people for economic prosperity. Furthermore , radio opened gates of jobs never known before. To become a broadcaster with a radio station was considered to have a prestigious job in the early days of radio. It still is. The news-readers, copy writers, playwright for radio dramas, anchors for different discussion shows, musicians, recording engineers and a range of technical jobs came about so quickly that colleges and universities had to run degree programs to meet the requirement of radio stations to employee staff in its various sections. Apart from the above matters radio also inculcates scientific temper among people, helps to enjoy the cultural activities and eradicates social superstitions and age-old dogmas. The role of radio in shaping the society and providing information and education is significant. Educational broadcasting is also useful for improving education and for enrichment purposes. The radio marked a turning point, in the way information was conveyed or transferred, because it used sound to capture the attention of audiences. Being the first communications medium that could transfer or transmit live voices over long distances, radio was and still is one of the most effective medium. People depended and still depend upon it as a source of important news, and information. The importance and optimum use of radio as a mass media was nowhere more evident than in World War 1. Radio was used to send diplomatic messages when Germany found out the British had tapped its cables. It made itself a medium that audiences found as their connection to all that happened worldwide. If they ever knew that television and the Internet, would take the world by storm in this day and age, they’d be blown away by how we’re advancing, and still in the running to make it bigger and better. We cannot deny that radio itself is an exclusive medium of the sound. It is an aural or auditory medium, a medium of the ear. There are three major elements of a radio broadcast: spoken-word, music and sound effects. They are all sounds carried on the air waves to the listener. T o be acceptable, all these sounds must be pleasant and expressive for the ears. They must be artistically integrated or mixed to provoke the imagination of the listener, otherwise, the intention of the broadcast would be defeated. Radio proved far more effective in mass communication as compared to the print media. The property of radio which did not require transportation of the message drew immense attention of common people and investors in the field of mass media. Once the radio technology was recognized as an effective means of communication, there was a race among companies and individuals to have their own radio facility. TELEVISION Television is now playing a very important role in our lives. Television is not only a convenient source of entertainment, but also a comparative cheap one. Television keeps us informed about current events. It allows us to follow the latest developments in science and politics. It also offers an endless series of programs that are both instructive and entertaining. Many television programs introduce people to things they never thought of before and have never heard of before. Television series have done a great job in popularizing many literary masterpieces. Besides, television has been good company to those who do not work, like housewives and lonely old people. The progression of television has come a long way from black and white and color TV to plasma and LCD TVs. The advent of this ever-changing medium started in the late 1930s, for entertainment and news purposes initially. Now, we have advertising, that has been incorporated into entertainment and news, to give viewers a chance to avail from products/services. There’s also a new way of accessing the Internet, by using a ‘Web TV’ that is hooked up instead of a PC, to browse information, and watch streaming videos on large LCD screens. After production of the TV program, a news channel has to make it available to the market, for those who are interested in viewing it. These programs can be talk shows, cooking shows, serials, movies and so on. There are two ways that is done. First/OriginalRun Once a program is completed by the producer, of either multiple or a single episode/s, he/she then wants a network or station to view it to audiences. These networks/TV stations already pay for the production themselves, or license a producer to do it instead before it is viewed to the people. Broadcast Syndication This is when secondary runs of a program, which go beyond its original first issue run, is again broadcast in other countries/locally and isn’t necessarily managed by the producer. In this case other TV stations, individuals or companies involve themselves in selling the product to available markets that they are allowed to showcase it to, usually under contract basis in some cases from the copyright holders/producers. With television people are still free to enjoy other â€Å"civilized pleasures†, or even more. There are a considerable variety of programs on television. The viewer is always free to choose whatever he wants to see. Furthermore, television provides enormous possibilities for education, like school programs via closed-circuit television as well as special broadcasts for those in a TV University or Open University. It also offers specialized subjects like language teaching, sewing, cooking, painting, cosmetics. Television does the job of education in the broadest sense. Instructive programs achieve their goal through entertaining the viewers. Moreover, television provides an outlet for creative talents and people all around the world are no longer distant and isolated from each other. It brings most distant countries and the strangest customs right into your living room. Compared with radio, everything on television is more lifelike, vivid, and real. Television may be a vital factor in holding a family together. Especially where there are economic problems that cause the husband and wife to be at a breaking point. There is no denying that television keeps people informed about the government and its programs . It also keeps people informed news and weather too. In addition , it ask people to be aware of certain disasters like floods, winds. In the case of serious problems television tells people what to do. Therefore, people can be taught about safety through television. On the other hand, television is an audio-visual and sophisticated scientific device. It telecasts programmes from far and wide areas of the country and abroad. It has an important role to play for entertainment and education of people all over the world. Environment pollution and ecological imbalances have challenged the life on the earth in modern times. Rapid population growth, urbanization problem of drain, huge stock of garbage, deforestation, evacuation of sarcastic gases from industry and automobiles are some of the reason of environment pollution. Necessity of clear environment for health and hygiene, needy of sanitation information about birth control devices are to be taught to mass through different programme. General awareness about the environment and its problems are raised through TV programmes. Socio-Political and Cultural achievement of the country described through different programmes to foster the sense of brotherhood among the people of different caste, creed and sex. Changing social systems, cultural and political issues are also brought for discussion and debate and exhibition on cultural exchange and political reviews are necessary for preservation of cultural values. Televisions another function is to provide entertainment to people through the programmes like Cinema, Serial, and Sports. Its role as an important communication medium is noteworthy for promoting national unity, developing economy and refining socio-cultural life of people. Its great contribution to humanity is education through different programmes. In short, we can never hide from the truth that television is very significant in our lives these days. It is very hard to imagine life without TV. It brings us together with some other cultures in other countries. It offers unending entertainment scenes and important information about life. It will still remain as a great medium of information that will still affect the people’s lives in the future generations. Internet Internet technology has paved the way to revolutionize all that we thought was either hidden or inaccessible. From the different types of media, the history of the Internet can be termed to be, by far, man’s greatest innovation story. The Internet has made it possible to contact others worldwide, nationally and locally; to send emails and be a part of chat rooms and conferences; blogging with discussion boards, opinion polls and forums; webcam viewing; global mapping using ‘Google Earth’ , sending and receiving images and files, downloading from the Internet through websites, signing up to a social networking websites, radio stations with live streaming , video streaming and lots more. It has stomped out conventional norms, with every teenager, adult and senior owning either a laptop or PC today. News can also be viewed via satellite with reporters covering events on site and sending it via the Internet to broadcasting news networks. It’s an amalgamation of uses, that is above all user-friendly and hi-tech. Using radio waves and frequency, not to mention satellite transmissions – we are able to access a whole new domain when it comes down to getting what we want and need within minutes. The Internet revolution has made it easier for people to get in touch, fuel business, make profits, shop and access free information from any Internet access enabled device. It is truly a technology that speaks for itself. The internet is a medium with which we can view information from anywhere in the world. Documents from the World Wide Web and various other services such as instant chat, email are available through the internet. Most of the time, everyone thinks that the internet and the W3 are the same, however this is not true. The internet is a network of cables, which allow users to access information of various sorts. The data is transmitted through the Internet Protocol, which is known as the IP. Each computer will have a separate identity when it comes to the use of the internet. Though the internet was available, it only became a household word in the year 1996. But at the beginning, the use of the internet was very expensive. Most of the users went to public centers to use the internet for a high price per hour. As the use became more popular, there was an increase in the speed of the internet and also decrease in cost. Networks were planned, and looking at the money, many service providers entered the market. They made it very simple for all users, and the use of the internet became very cheap. Everyone at home could afford to get a connection, and now most users will have unlimited access as well. This has made it possible for many people to benefit. Those who are unable to go out may get opportunities to work from home. Various other doors have been opened to the average human, and everyone has taken advantage of the creation. Almost every individual uses the internet where it is available, irrespective of age groups. This medium caters to the needs for all age groups. The internet has made a lot of activities very easy. The medium is used for almost all purposes, even with important issues such as education and government organizations. It has come a long way from the use with only scientific organizations and institutes etc. There was a phenomenal growth in the years 1996 and 1997. The growth for the internet has been at around hundred percent per year. Majority of the users use the English language for the internet, as computer development happened in America in all stages. There are other languages as well, such as French, German, Chinese and Arabic. Internet has also made life easy because we can view through various means. The internet has been improved through time; it took many years of improving to become what people know it today. The internet has affected people’s lives in different ways, but unfortunately some people use this easy and fast technology to do unacceptable things. Internet helps individuals in communications because it is fast and effective. And that’s why organizations started to use this technology to provide information about their activities and open the door for easy and fast communications with individuals. However, it is not correct that all changes in values caused by the internet are negative. People must think about what positive changes that internet could make. The Internet actually embodies high and strong values from which it derives an almost   irresistible strength. These include physical values such as speed, timeliness, efficiency   and productivity. The government uses the internet in something called the â€Å"E-government†. The E-government â€Å"is a general term describing the use of technologies to facilitate the operation of government and the disbursement of government information and services†. By using the E-government, people can reach the government more easily and quickly. It also can be used to provide information for citizens; citizens are able to read information in the time and place they want. If a citizen wants to send an application or a document for a certain purpose, he can do it easily and quickly with the E-government technologies (E-government). Despite all the negativities of the internet, the benefits of using it are much greater than the harms. The society was affected by internet, and internet will keep affecting society and its values always. Maybe one day all the society activities will be managed by the internet. TELEGRAPH A telegraph is any system that transmits encoded information by signal across a distance. Although it is associated with sending messages via an electric current, the word telegraph was coined to describe an optical system of sending coded messages. From its invention until the telephone   became a viable system, the telegraph was the standard means of communicating both between and within metropolitan areas in both  Europe  and the United States. Telegrams and telexes used telegraphy but are rapidly being replaced by facsimile (fax) transmissions through telephone lines. Satellite  transmission and high-frequency radio bands are used for international telegraphy. The telegraph was the result of a slew of inventions from all over the world. Many are unaware of the fact that the telegraph actually â€Å"preceded the railroad in forging extra local and interregional links. The reason for this was that the telegraph was used primarily for business reasons. Prior to the creation and distribution of the telegraph, America experienced a â€Å"business revolution. As the business demand grew, there was a drift towards a â€Å"natural monopoly† of the telegraph industry. This monopoly allowed the major telegraph firms to increase the prices of the telegraph which undoubtedly prevented many people in society from using this invention for private and personal reasons. In fact, the public could not afford to pay the high costs but telegraph companies knew business firms could, so they did not use the telegraph as a means of communication. In America, the telegraph was only able to gain popularity because of the demand placed on it by business firms. It wasn’t until the invention of the telephone that the public began to truly utilize such a communicating device. As we know, the electric telegraph was one of the first telecommunications technologies of the industrial age. Its immediate predecessors were homing pigeons, visual networks, the Pony Express, and railroads. By transmitting information quickly over long distances, the telegraph facilitated the growth in the railroads, consolidated financial and commodity markets, and reduced information costs within and between firms. This entry focuses on the industrial organization of the telegraph industry from its inception through its demise and the industry’s impact on the American economy. The telegraph was similar to many other inventions of the nineteenth century. It replaced an existing technology, dramatically reduced costs, was monopolized by a single firm, and ultimately was displaced by a newer technology. It is nearly impossible to determine the full extent to which the telegraph changed the way people lived. It was not so much because ordinary citizens made use of it on a regular basis. In fact, it was a rather expensive means of communication that mostly appealed to big business and government. But telegraph lines followed the westward expansion of the railroad across North America. They made it possible to communicate quickly over vast distances and they linked far-flung settlements with population centers back east. This helped foster a stronger sense of national identity and underscored the need for more standardization and uniformity. The invention of the telegraph could in some ways be seen as the real beginning of our modern age, given the way in which it so interconnected the entire world. Almost coincidental with its birth  there was the emergence of a new kind of journalism that made currency its stock in trade. Reporting events that had only just occurred took precedence over a newspaper’s traditional editorial role, and news was reported almost as soon as it happened. Corporations also could become larger and more far-flung, and nations became necessarily more interdependent. With the telegraph, information in all its aspects and forms which began to assume the critical role it plays today. Last but not least, the telegraph proved especially useful to the military. It was first used for these purposes in 1854 by the Allied Army in Bulgaria during the Crimean War. A transcontinental telegraph line had been completed in the United States just as the Civil War began, and the telegraph proved enormously useful to both sides. During the Spanish-American War in 1898, undersea telegraph cables were cut as an act of belligerency for the first time, and in World War I, teleprinters with secret codes were heavily used by all combatants.

History of instant noodles free essay sample

History of Instant Noodles Instant noodles are dried precooked noodles fused with oil, usually eaten after being cooked or soaked in boiling water for 3 to 5 minutes. A flavor packet is almost always included with a packet of instant noodles. The product may also be consumed raw from the packet, as the noodles are already cooked, usually by frying Instant noodles originate from instant versions of the Japanese dish ramen The idea of instant noodles can be traced back to the Chinese Qing Dynasty, when yimian noodles were deep-fried which allowed them to be stored for long periods and then prepared quickly. Similarly, Chicken Thread Noodles (deep-fried thin noodles served with boiling water and optionally an egg) were available in China and Taiwan since Qing Dynasty. Modern instant noodles were invented in Japan by businessman Momofuku Ando ( ), the founder of Nissin, one of the biggest manufacturers of instant noodles today. His noodles were boiled with flavouring, deep-fried with palm oil to remove moisture, and dried into a noodle cake. Other preservation methods have been tried, including preservation with salt and smoke, but Ando concluded that palm oil is the most efficient. In 1958, Nissin launched the worlds first instant noodle product, Chikin Ramen (chicken-flavored instant ramen) in Osaka. Another milestone was reached in 1971 when Nissin introduced the Cup Noodle, instant noodles in a waterproof styrofoam container that could be used to cook the noodles. Further innovations include adding dried vegetables to the cup, creating a complete instant soup dish. According to a Japanese poll in the year 2000, instant noodles were the most important Japanese invention of the century. Karaoke came second, with the compact disc only coming in fifth. As of 2002, approximately 65 billion servings of instant noodles are eaten worldwide every year. Instant noodles are not only popular with college students; they can also be an economic indicator. In 2005, the Mama Noodles Index was launched to reflect the sales of Mama noodles, the biggest manufacturer in Thailand. The index was steady since the recovery from the East Asian financial crisis, but sales jumped by around 15% in first seven months in 2005 on year-to-year basis, which was regarded as a sign of recession. People could not afford  more expensive foods, hence the increase in the purchase of ramen, as ramen is seen as an inferior good in Thailand. In the Nepali context, instant noodle was introduced in Nepal in late 1980’s with very low levels of popularity which was effectively addressed with aggressive marketing strategies. The instant noodle industry is today among the major industries of the country with an annual income of more than four hundred core rupees. Hi mshree Noodles (manufacturers of RARA) and Chaudhary Group (WAI WAI) played the biggest role in the success of instant noodles in Nepal. Currently, the instant noodles industry employs over 10,000 people. Present scenario of noodles industries in Nepal: Noodles have become a necessary item in the Nepali consumers shopping list. Although homemade noodles have long been there, it was only in 1984 that a major brand came into the picture. It was virtually a monopoly market for the noodle leader -Wai Wai, with an 80 per cent market share, while other brands formulated the rest of the noodle market until the year 2000 when two other brands from different companies were launched RumPum and Mayos. Ever since, there has been a mushrooming of various noodle brands. With more than 40 brands on the market hot plate, the industry is still growing. 1. Competition and price sensitivity: The intensity of the competition among the players can be gleaned from the fact that the price of the product has remained constant for a considerable period of time. Despite the heavy increase in costs price of flour, machinery, maintenance, labour and packaging, the price remains the same. While the consistency in price works in favour of the consumer, the profit margin for the producer has declined. The promotional campaigns of the noodle industry have further reduced the margin for the producer. The competition has now led the whole noodle industry to a sales volume generating market where only the big players can survive. No unique development has been made in the product quality so far, although it might me said that a few of the products come with unique differentiation the addition of vegetable cubes, flavoured seasoning and different foil packaging. Each of the companies has a number of products to offer ? snack noodles, white noodles, instant noodles and some others with a different seasoning to capture the market. Every company is in the quest of producing a different noodle brand, but only a handful have succeeded. Each of the companies has a different approach to marketing. While Mayos positions itself as the family noodle, Wai Wai is a noodle for all, Shaka-laka-boom is for the kids and so on. Promotional activities are not restricted to advertisements and trade only: the driving factor here is the consumer scheme. From every noodle packet placed on the retail shelf, a consumer hopes to win something. This new millennium has brought consumers more value to whatever they are paying for. Before this, only a couple of imported brands from India and Thailand offered bowls or spoons as an add-on value to the product. Domestic brands played the game with exchange offers a collection of wrappers got you a free gift. The year 2000 saw Rumpum launch the first ever scheme Bingo hungama closely followed by the market leader Wai Wai with mauka ma chauka, with both the noodles drawing higher sales. Mayos also dove into the pool with Say Ma Say Uphar. Since then none of the companies has dared to take off the schemes from the noodles. But the question is, can a scheme-driven brand build its image? Do activities generating sales contribute to the image-building process? Companies are investing heavily on consumer promotional activities whether it is at the distribution level or in their communication. If we evaluate the importance given to a brand name in any of the messages, we see how little attention is given to the brand name. The products scheme positioning differs from its brand positioning whereas it should have remained in alignment with any new promotional campaign. For example, the Wai Wai tag line suggests that it is â€Å"Hami Sabai ko Wai Wai (Our Wai Wai), but its latest scheme is gender-biased and says Wai Wai Hero. Thus, the main theme of the brand often gets diluted, brands are not being built, and the thrust is only on a time-bound campaign. Today the consumer is more concerned about the value addition of each brand, to the extent that packaging, color, nutritional values, date of manufacture and taste are sidelined. This means that the consumer cares less about the brand and is buying solely for the gifts offered. 2. Brand loyalty What Wai Wai was able to achieve with its brand before the offer war is something that will be hard to achieve in the present scenario. For example, no matter what another soft drink offers, a Coca Cola consumer will only drink Coke. The brand loyalty is so strong that the consumer feels proud to be a Coke consumer. Brand managers in the Nepali noodle market must wear their thinking caps because today a noodle is just a noodle SWOT analysis of Noodles industry. SWOT analysis is the exercise in which the organization identifies its strength (S) and weakness (W), and environmental opportunity (O) and threat (T). The firm identifies these through the process of environmental scanning. While scanning the external environment, the organizations try to identify both opportunities and threats confronting the firm. It obtains the data about economic, financial, political, legal, social, and competitive changes in the various markets that firm serves. External environmental scanning also yields data about external threats to the firm such as increasing competition, migration, policy of the government etc. In conducting the SWOT analysis, the organization internal environment i.e. , strength and weakness as well as the external environment i. e. , threat and opportunities should also be accessed which are discussed below: Strength: Strength is an inherent capacity, which an organization can use to gain strategic advantage. Organizational strength is skills, resources, and other advantages the firm possesses relative to its competitors. Potential strengths, which form the basis of a firm’s dis tinctive competence, might include managerial skills, efficient technology, well-known brand names, a good public image, and strong market shares. An example of strength is superior research and development so that the company can gain a strategic advantage. The strengths of the Noodles industry are: Quality of output and distribution network Better packaging like metal wrappers, its life can be prolonged by another 2-3 months. Different taste, price and targeted for different groups Market leaders like Chaudhary Group and Asian Thai foods make a routine exercise to replace date expired noodles with fresh ones from the shelves for domestic as well as foreign markets. (difference is in pricing , packaging and variety. Expired noodles are destroyed. Strict quality control is a priority with the market leaders. Effective supply chain management Weakness: A firm that is formulating strategic plan also needs to acknowledge its organizational weaknesses. A weakness is an inherent limitation or constraint, which creates strategic, disadvantages. These weaknesses reflect deficiencies or shortcomings in skills, resources, or other factors that hinder the firm’s competitiveness. They may include poor distribution networks, poor labor relations, lack of skilled managers, or lack of product development efforts. An example of a weakness is over dependence on single product line, which is potentially risky for a company in times of crisis. The weaknesses of the Noodles industry are: Lack of self owned technical requirements Rising manufacturing/building cost Opportunities: An Opportunity is favorable condition in the organizations environment, which enables it to consolidate and strengthen its position. An example of an opportunity is a growing demand for the product or services that a company provides. The opportunities of Noodles industry are: Brand awareness and quality consciousness among consumers International markets Exporting noodles to various countries like India, Bhutan, Hongkong, Qatar and U. K Threats: A threat is an unfavorable condition in the organizations environment, which creates a risk for the organization. An example of threat is the emergence of strong new competitors who are likely to offer stiff competition to existing companies in an industry. The Threats of the Noodles industry are: Government policies Political instability Unnecessary shortage of market Severe losses to the entrepreneur Misconception that the quality and the taste of almost all noodles are similar

The AIDS virus is one of the most deadly and most Essay Example For Students

The AIDS virus is one of the most deadly and most Essay AZTAZT wide spread diseasesin the modern era. The disease was first found in 1981 as doctors around theUnited States began to report groups of young, homosexual men developing a rarepneumonia caused by an organism called Penumocystis carini. These patients thenwent on to develop many other new and rare complications that had previouslybeen seen only in patients with severely damaged immune systems. The Center forDisease Control in the United States named this new epidemic the acquiredimmunodeficiency syndrome and defined it by a specific set of symptoms. In 1983,researchers finally identified the virus that caused AIDS. They named the virusthe human immunodeficiency virus, or HIV. AIDS causes the immune system of theinfected patient to become much less efficient until it stops working altogether. We will write a custom essay on The AIDS virus is one of the most deadly and most specifically for you for only $16.38 $13.9/page Order now The first drug that was approved by the American Food and Drugadministration for use in treating the AIDS virus is called AZT, which standsfor azido-thymidine. AZT was released under the brand name of Retrovir and itschemical name is Zidovudine, or ZDV. The structural name of AZT is 3-azido-3-deoxythymidine. AZT works by inhibiting the process of copying DNA in cells. More specifically, AZT, inhibits the reverse transcriptase enzyme, which isinvolved in the DNA replication process. When DNA is replicating in a cell,there is a specific enzyme that works along one side of the original DNA strandas the DNA is split into two strands, copying each individual nucleotide. Thisenzyme is only able to work in one direction along the nucleotide string,therefore a different enzyme, or rather a series of different enzymes isrequired to work in the opposite direction. Reverse transcriptase is one of theenzymes that is required to work in the opposite direction. AZT works by bondingto the reverse transcriptase enzyme, thereby making it unable to bond with thenucleotide string and making it unable to fulfill its role. This whole processis used by the HIV virus to replicate itself so that it can continue to infectmore cells. AZT was originally developed over 20 years ago for the treatment oflukemia. The concept behind this was that the AZT was supposed to terminate theDNA synthesis in the growing lukemia lymphocytes, thereby stopping the disease. AZT was rejected at this point because it failed to lengthen the lives of testanimals. The problem with the AZT drug is that it is not perfect. First of all,AZT will not bond to each and every reverse transcriptase enzyme in the body,and therefore it cannot shut down the HIV production completely. The reason forthis is because to put enough AZT in the patient to completely shut down the HIVproduction would probably kill the patient. The second, and most serious problemwith AZT is that it also goes into normal, healthy cells and will inhibit theirreverse transcriptase enzyme and will therefore inhibit their ability to producenew, healthy cells. However, AZT does have an ability to specifically target HIVinfected cells to a certain degree so that it does not kill each and every cellit gets into. However, it does kill a high proportion of the cells that it getsinto, thereby giving it a high toxicity level. The formula for AZT is C H N O . The molar mass of AZT is 267.24 gramsper mole. AZTs melting point is between 106 C and 112 C. AZT is soluble inwater, which is important so that it may dissolve into the human blood and bedistributed to the cells. AZT is usually taken in a pill format, but it isabsorbed by the skin, which can make it dangerous for people handling the drug. .uab596cb28a1d7692ffb45d67e4df3c81 , .uab596cb28a1d7692ffb45d67e4df3c81 .postImageUrl , .uab596cb28a1d7692ffb45d67e4df3c81 .centered-text-area { min-height: 80px; position: relative; } .uab596cb28a1d7692ffb45d67e4df3c81 , .uab596cb28a1d7692ffb45d67e4df3c81:hover , .uab596cb28a1d7692ffb45d67e4df3c81:visited , .uab596cb28a1d7692ffb45d67e4df3c81:active { border:0!important; } .uab596cb28a1d7692ffb45d67e4df3c81 .clearfix:after { content: ""; display: table; clear: both; } .uab596cb28a1d7692ffb45d67e4df3c81 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uab596cb28a1d7692ffb45d67e4df3c81:active , .uab596cb28a1d7692ffb45d67e4df3c81:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uab596cb28a1d7692ffb45d67e4df3c81 .centered-text-area { width: 100%; position: relative ; } .uab596cb28a1d7692ffb45d67e4df3c81 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uab596cb28a1d7692ffb45d67e4df3c81 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uab596cb28a1d7692ffb45d67e4df3c81 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uab596cb28a1d7692ffb45d67e4df3c81:hover .ctaButton { background-color: #34495E!important; } .uab596cb28a1d7692ffb45d67e4df3c81 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uab596cb28a1d7692ffb45d67e4df3c81 .uab596cb28a1d7692ffb45d67e4df3c81-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uab596cb28a1d7692ffb45d67e4df3c81:after { content: ""; display: block; clear: both; } READ: Walt Disney Yen Financing EssayThere is quite a bit of controversy about the effectiveness of AZT. Mostexperts agree that AZT delays the progression of HIV disease; the drug may alsoprolong the disease-free survival period. However, many doctors still disagreewith using AZT as a treatment for AIDS. Peter Duesberg, a professor of molecularbiology at the university of California, Berkley, says that In view of this,the cytotoxicity level of AZT there is no rational explanation of how AZTcould be beneficial to AIDS patients, even if HIV were proven to cause AIDS.This comment stems from the fact that AZT has a very high cytotoxicity level,which means that while it kills the inf ected cells, it will also kill perfectlyhealthy cells. According to Dr. Duesberg, AZT will kill approximately ninehundred and ninety nine healthy cells for each infected cell that it kills. Mostof this opposition to AZT stems from the fact that the initial testing for thedrug had severe problems associated with it. These initial tests were performedwith two groups of AIDS patients. The volunteering patients were secretlydivided into two groups using a double-blind system, where neither the patientsnor the doctors are aware of who is in the placebo, or control group, and who isin the AZT group. These tests were performed by the FDA at twelve medicalcenters throughout the United States. The study actually became unblinded almostimmediately as some patients discovered a difference in taste between theplacebo and AZT caplets and other patients took the capsules to chemists to havethem analyzed. The doctors found out the differences between AZT patients andthe placebo patients by very ob vious differences in blood profiles. An FDAmeeting was convened and the decision was made to keep all of the useless data,and therefore the bad data was thrown in with the good data and it ended upmaking all of the data virtually useless. In fact, according to some sources,AZT ended up shortening the lifespans of many of the patients taking it. AZT isalso thought to be a possible carcinogen, although it has not been around longenough for any conclusive results to be obtained. After AZT was approved for use,mortality statistics were taken, they showed a mortality rate of 10% after 17weeks, with the original number of patients being 4805. The FDA tests, withtheir skewed statistics, showed only a 1% mortality rate. AZT also had somestrange side-effects that were reported with its use, such as raising the IQsof 21 children who took the drug by 15 points, 5 of the children died. The newest treatments with AZT are combining AZT with other drugs, suchas ddI. These tests were being performed, once again in the double-blind format,just like the original FDA tests. Three different groups were tested, onestaking only AZT, ones taking only ddI and ones taking a combination of both ddIand AZT. The Data Safety Monitoring Board (DSMB), and organization that monitorsall testing in the United States secretly unblinded the test, as they do withall double-blind tests, and found that the AZT patients had a much highermortality rate than those in the straight ddI and the ddI and AZT tests. TheDSMB found the difference in the tests to be high enough to stop the trialsearly. In August of 1994, the FDA approved AZT for use by pregnant, AIDSinfected women. Once again it was conducted in a double-blind method and wasplacebo controlled. The therapy was begun 14-34 weeks after pregnancy. However,in this testing it was found that in the AZT mothers, the AIDS transmission rateto the babies was about 8.3% while the placebo group was about 25.5%. Thereforethe AZT was reducing the AIDS transmission by two thirds. .u438316db6e91d6997f76c8a8a28eee7c , .u438316db6e91d6997f76c8a8a28eee7c .postImageUrl , .u438316db6e91d6997f76c8a8a28eee7c .centered-text-area { min-height: 80px; position: relative; } .u438316db6e91d6997f76c8a8a28eee7c , .u438316db6e91d6997f76c8a8a28eee7c:hover , .u438316db6e91d6997f76c8a8a28eee7c:visited , .u438316db6e91d6997f76c8a8a28eee7c:active { border:0!important; } .u438316db6e91d6997f76c8a8a28eee7c .clearfix:after { content: ""; display: table; clear: both; } .u438316db6e91d6997f76c8a8a28eee7c { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u438316db6e91d6997f76c8a8a28eee7c:active , .u438316db6e91d6997f76c8a8a28eee7c:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u438316db6e91d6997f76c8a8a28eee7c .centered-text-area { width: 100%; position: relative ; } .u438316db6e91d6997f76c8a8a28eee7c .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u438316db6e91d6997f76c8a8a28eee7c .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u438316db6e91d6997f76c8a8a28eee7c .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u438316db6e91d6997f76c8a8a28eee7c:hover .ctaButton { background-color: #34495E!important; } .u438316db6e91d6997f76c8a8a28eee7c .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u438316db6e91d6997f76c8a8a28eee7c .u438316db6e91d6997f76c8a8a28eee7c-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u438316db6e91d6997f76c8a8a28eee7c:after { content: ""; display: block; clear: both; } READ: Psychodynamic view EssayIt is still not clear as to the effectiveness of AZT to stop or hinderthe progress of the AIDS virus.

Unknowingly Living With Mental Illnesses Professor Ramos Blog

Unknowingly Living With Mental Illnesses Mental illnesses have increased throughout a period of years and people have accepted them into their daily routines, so much so, that it almost seems like a normal thing to cope with. But what people do not ask themselves often is how did this ailment begin? In the story â€Å"Never Marry a Mexican† by Sandra Cisneros, she introduces a character named Clemencia- a troubled young women with a history of family problems and a natural instinct to self destruct. I am writing about this story because in a way, Clemencia and I have similarities. She and I both had a mother who cheated on her husband and we both have emotional scars that were never properly healed. A type of trauma like this stays with a person for a while and sometimes forever, especially if they do not learn how to forgive, accept, and move on. A child’s adolescence is the rise of their future characteristics; you can either let nature  raise a child or you can nurture them, though, however you choose, there will be some kind of psychology applied to their environment. Clemencia grew up in more of a nature environment being left to fend for herself and it seemed to have caused her psychological distress: â€Å"psychological discomfort that interferes with your activities of daily living. Psychological distress can result in negative views of the environment, others, and the self.† (study.com). Some symptoms of P.D. are obsessive thoughts or compulsions and reckless acts. Clemencia did not show too much happiness throughout the affair because she knew Drew was a man who would never stay with her when the sun would rise or no matter how many times she asked him to leave his wife for her, he would not. But she did find joy through secretly taunting Megan by having a romantic affair with her husband. Reckless ac ts like Clemencia’s are not considered normal and rather unhealthy. She knew her actions were specifically meant for bad intentions and pursued them to feel satisfaction. Though this story did not mention Clemencia having any mental illnesses, it could be one explanation for her erratic behavior. When her father had passed away, she was not given the proper care to grief and move on. She did not have the support of her mother to hold her and tell her everything would be okay. When her mother passed away, Clemencia felt nothing anymore. Not towards her mother, not towards her students, and not towards the affair she was having with Drew. A symptom like this is a sign of a sociopath: â€Å"a person with a psychopathic personality whose behavior is antisocial, often criminal, and who lacks a sense of moral responsibility or social conscience.† (Dictionary.com). A sociopath can be spotted through many observations but a specific symptom that resembled Clemencia was â€Å"Lack of remorse and shame† (Psychology Today). When she and Drew were having an affair, Clemencia never stopped to think about how this would affect his marriage and what hi s wife Megan would think of it. She enjoyed being a mistress in general but she was obsessed with Drew the most. She also never considered how this might possibly affect her personally in the future when she tries maturing and finding a healthy relationship. Actions like hers are capable of causing her more trauma than what she has already experienced. Another symptom Clemencia had was â€Å"Absence of delusions and other signs of irrational thinking†. (Psychology Today). When Drew was being phoned at four in the morning, Megan answered with a polite voice. Megan was not aware the phone was from her husband’s mistress, but this senseless act brought Clemencia an overpowering feeling of satisfaction and joy. All she could say to him was â€Å"Drew? That dumb bitch of a wife of yours†¦ that stupid stupid stupid†¦ Excuse me, honey. It cracked me up.† (Cisneros 61). Clemencia showed her worst possible behavior when she began putting gummy bears inside of Megan’s personal belongings. I understand Drew should have never gotten involved with anyone if we was already married. But I do not understand how Clemencia could be this delusional to stash gummy bears inside of his wife’s personal belongings- in places only Megan would look. Only a person who is emotionally distressed can be capable of sc heming at this level. A sociopath tends to have an oversized ego during a relationship. Many times Clemencia tried to convince Drew he was nothing without her. â€Å"They are narcissists to the extreme, with a huge sense of entitlement† (Huffington Post). She would take credit for the man he was and spoke of herself sounding pompous. Towards the end of the story, she spoke to Drew’s son, making her side of the story sound as if Drew was responsible for her acts and failures. But the very last symptom Clemencia proved to possibly be a sociopath was her talk of suicide. She was not convinced in the end of her story that she would ever actually commit suicide. But she did speak of it and consider it towards herself and the possible death of others. Though her suicide thoughts are in her mind- a sociopath never actually carries on the thought. That does not mean she is not a threat to other people. Her traumatic situation impacted her life gradually and even though she did not act physically vio lent, Clemencia’s past could still affect her future. Who knows what actual disorder she could have had and what risks come with it. To my readers- please be careful out there.

Resilient Cultures by Kicza, John Essay Example | Topics and Well Written Essays - 500 words

Resilient Cultures by Kicza, John - Essay Example This means that those in the east and the north adopted maize farming from the Mexicans or the natives of south west American (30). The Europeans had failed to change the farming system of the Northerners for several years. My thought was, the natives of the east and the north had resisted the European farming system for several years. There are several religious systems in America such as Christianity, Islam, Buddhism, and Hinduism. The native Indians in America had their religious believes before the coming of the Europeans. Slave trade had existed in several European countries before they colonized America. Some of the slaves were taken to work on plantations in America (60). These slaves were captured from different regions in Africa and some from Asia. It could be possible these religious beliefs were introduced by the interaction between the slaves and the American natives. Christianity was dominant among the Europeans, and it was spread across the world. This means that the Europeans introduced Christianity to the Americans and the slaves introduced other religions. Some of the slaves settled permanently in America and had to establish their places of worship. In the second half of the fifteen century, the eastern section of America had begun building the 13 colonies, and Virginia was established in 1607. This shows that as Europe and the Ottoman Empire were dominating, America was advancing. The Americans had acquired architectural design skills from the Europeans. Historically when the Ottoman Empire controlled the Mediterranean, they took silk, spices, porcelain and other valuables from Europe. Applying the same to America, Christopher Columbus was not only looking for a shorter route to china but was also looking for valuable skills and spices in Europe (78). This gave the Americans the wealth and the skills needed to build the colonies and develop the economy of the country. Aztec was an

Waiting for Superman (2010) Film Essay Example | Topics and Well Written Essays - 750 words

Waiting for Superman (2010) Film - Essay Example The director of the movie is Davis Guggenheim, and the producer is Lesley Chilcott. Several students are used to reflect as they struggle to be accepted in the charter school. The Audience Award honored the film in 2010 as one of the best documentary. This paper seeks to focus on ‘Waiting for Superman’ (2010) film. In the film waiting for the superman (2010), several problems are identified as an impediment to quality education standards. One of the problems is the tiresome process one is supposed to undergo  in order to get a place in the schools thought to be best performing. Those schools that are best, and have spaces depend on lottery for enrollment, hence denying chance to many students. Consequently, they are forced to go through schools whose performances rank low in all aspects of academics. The other significant policy problem identified in this issue is bureaucracy employed by the teachers union. Most of the teachers are unable to inject their knowledge to s upport students to achieve satisfactory grades. Furthermore, those teachers identified to contribute to poor performance of the student are not fired. They are protected by security of tenure, which is easily acquired after two years of teaching. The other problem identified by the movie is the issue of perception that individual background determines the level of performance. He disputes this fact and notes if such individual are exposed to formal education standards, and have exceptional teachers they are more likely to make it to the college. There is also lack of motivation of exceptional performing teachers as their payments are standardized (Participant Media and Weber 17-22). Many causes have led to various policy problems as identified by the film. The most notable is the bureaucracy of the teacher union. Even after identification of poorly performing teacher, it takes a long time, for such teacher to be expelled. In addition, the union contract is a source of impediment to school reforms. Such a teacher also continues receiving money from the exchequer. The other challenge is the issue of United States standardized test scores. This score continues to fall since the early seventies affecting performance significantly. Moreover, charter schools enjoy certain provisions that are not in public schools. They have the rights to have longer school days and schools years while this is reduced in public schools. He also identifies failure in public schools because of strict mechanism that are applied to the students. Some rules in public according to the film are conservative and retrogressive (Participant Media and Weber 17-22). According to Guggenheim film, quality education is composed of great teachers, prepared students, excellent schools and an increased level of literacy (Film). Furthermore, it claims such quality education produces outstanding graduate. There are several proposed policy instruments to quality education performance. The most important is the motivation of teachers based on their performance. He proposes such teachers should be given some form of incentives such as salary increase. The other important step is to raise education status to international standards. He also proposes that there should be an increase in literary rates. The film also calls for providing a successful school experience for all students. The movie also supports the establishment of more charter schools to increase enrollment. He also advocates getting rid of teachers union as a

Art - Essay Example It is true that media artists today consider both aesthetics and ethics in their work. In the current investigation, my point of view is that the most important thing in a work of art is its ethical qualities, because no matter how hard one tries, one cannot get away from ethics. To me, concentrating wholly on form and ignoring ethics is basically blinding oneself to a critical aspect of artistic creation and (especially) consumption. Television, movies, and other media arts are judged in terms of morality and ethical qualities as a foremost consideration; to ignore this aspect borders on folly. Media arts are made for public consumption, and part of this public consumption is the ethical judgment of the genre and the product. Television must pass censorship standards, and movies must pass ratings standards. When people watch a movie, especially a mass-market production, they are often watching an ethical polarization of good and evil (good guys vs. bad guys). And if there is ambiguity between who is the bad guy and the good guy, this is also a moral or ethical question. â€Å"From our casual conversations about the moral status of cinematic villains and heroines, through debates about the effects of the portrayal of violence by Hollywood International, to arguments about the portrayal of sex and sexuality, film talk is intimately tied up with ethical concerns and evaluations† (Meskin, 2009). The same can be said of talk about other media arts, especially television, which seeks to appeal to a mass market kind of morality or ethics. To say that media arts is only for malism is all well in good in a very limited art-house context, but to consider the real situation, one must accept the mass-media perspective. In this perspective, ethics and morality are explicitly involved in the consumption of media arts. One cannot subtract ethics from this consideration; to do so would be to lose a large piece of the puzzle in terms of how human beings react

In peer to peer network there are no dedicated servers or hierarchy among the computers. The user must take the decisions about who access this network. Processors In 1945, the idea of the first computer with a processing unit capable of performing different tasks was published by John von Neumann. The computer was called the EDVAC and was finished in 1949. These first primitive computer processors, such as the EDVAC and the Harvard Mark I, were incredibly bulky and large. Hundreds of CPUs were built into the machine to perform the computers tasks. Starting in the 1950s, the transistor was introduced for the CPU. This was a vital improvement because they helped remove much of the bulky material and wiring and allowed for more intricate and reliable CPUs. The 1960s and 1970s brought about the advent of microprocessors. These were very small, as the length would usually be recorded in nanometers, and were much more powerful. Microprocessors helped this technology become much more available to the public due to their size and affordability. Eventually, companies like Intel and IBM helped alter microprocessor technology into what we see today. The computer processor has evolved from a big bulky contraption to a minuscule chip. Computer processors are responsible for four basic operations. Their first job is to fetch the information from a memory source. Subsequently, the CPU is to decode the information to make it usable for the device in question. The third step is the execution of the information, which is when the CPU acts upon the information it has received. The fourth and final step is the write back. In this step, the CPU makes a report of the activity and stores it in a log. Two companies are responsible for a vast majority of CPUs sold all around the world. Intel Corporation is the largest CPU manufacturer in the world and is the maker of a majority of the CPUs found in personal computers. Advanced Micro Devices, Inc., known as AMD, has in recent years been the main competitor for Intel in the CPU industry. The CPU has greatly helped the world progress into the digital age. It has allowed a number of computers and other machines to be produced that are very important and essential to our global society. For example, many of the medical advances made today are a direct result of the ability of computer processors. As CPUs improve, the devices they are used in will also improve and their significance will become even greater. VGA The term Video Graphics Array (VGA) refers specifically to the display hardware first introduced with the IBM PS/2 line of computers in 1987,[1] but through its widespread adoption has also come to mean either an analogue computer display standard, the 15-pin D-sub miniature VGA connector or the 640Ãâ€"480 resolution itself. While this resolution has been superseded in the personal computer market, it is becoming a popular resolution on mobile devices. Video Graphics Array (VGA) was the last graphical standard introduced by IBM that the majority of PC clone manufacturers conformed to, making it today (as of 2009) the lowest common denominator that all PC graphics hardware supports, before a device-specific driver is loaded into the computer. For example, the MS-Windows splash screen appears while the machine is still operating in VGA mode, which is the reason that this screen always appears in reduced resolution and colour depth. VGA was officially superseded by IBMs XGA standard, but in reality it was superseded by numerous slightly different extensions to VGA made by clone manufacturers that came to be known collectively as Super VGA. VGA is referred to as an array instead of an adapter because it was implemented from the start as a single chip (an ASIC), replacing the Motorola 6845 and dozens of discrete logic chips that covered the full-length ISA boards of the MDA, CGA, and EGA. Its single-chip implementation also allowed the VGA to be placed directly on a PCs motherboard with a minimum of difficulty (it only required video memory, timing crystals and an external RAMDAC), and the first IBM PS/2 models were equipped with VGA on the motherboard. RAM Random-access memory (usually known by its acronym, RAM) is a form of computer data storage. Today, it takes the form of integrated circuits that allow stored data to be accessed in any order (i.e., at random). The word random thus refers to the fact that any piece of data can be returned in a constant time, regardless of its physical location and whether or not it is related to the previous piece of data. By contrast, storage devices such as tapes, magnetic discs and optical discs rely on the physical movement of the recording medium or a reading head. In these devices, the movement takes longer than data transfer, and the retrieval time varies based on the physical location of the next item. The word RAM is often associated with volatile types of memory (such as DRAM memory modules), where the information is lost after the power is switched off. Many other types of memory are RAM, too, including most types of ROM and flash memory called NOR-Flash. An early type of widespread writable random-access memory was the magnetic core memory, developed from 1949 to 1952, and subsequently used in most computers up until the development of the static and dynamic integrated RAM circuits in the late 1960s and early 1970s. Before this, computers used relays, delay line memory, or various kinds of vacuum tube arrangements to implement main memory functions (i.e., hundreds or thousands of bits); some of which were random access, some not. Latches built out of vacuum tube triodes, and later, out of discrete transistors, were used for smaller and faster memories such as registers and random-access register banks. Modern types of writable RAM generally store a bit of data in either the state of a flip-flop, as in SRAM (static RAM), or as a charge in a capacitor (or transistor gate), as in DRAM (dynamic RAM), EPROM, EEPROM and Flash. Some types have circuitry to detect and/or correct random faults called memory errors in the stored data, using pa rity bits or error correction codes. RAM of the read-only type, ROM, instead uses a metal mask to permanently enable/disable selected transistors, instead of storing a charge in them. As both SRAM and DRAM are volatile, other forms of computer storage, such as disks and magnetic tapes, have been used as persistent storage in traditional computers. Many newer products instead rely on flash memory to maintain data when not in use, such as PDAs or small music players. Certain personal computers, such as many rugged computers and net books, have also replaced magnetic disks with flash drives. With flash memory, only the NOR type is capable of true random access, allowing direct code execution, and is therefore often used instead of ROM; the lower cost NAND type is commonly used for bulk storage in memory cards and solid-state drives. Similar to a microprocessor, a memory chip is an integrated circuit (IC) made of millions of transistors and capacitors. In the most common form of computer memory, dynamic random access memory (DRAM), a transistor and a capacitor are paired to create a memory cell, which represents a single bit of data. The transistor acts as a switch that lets the control circuitry on the memory chip read the capacitor or change its state. Types of RAM Top L-R, DDR2 with heat-spreader, DDR2 without heat-spreader, Laptop DDR2, DDR, Laptop DDR 1 Megabit chip one of the last models developed by VEB Carl Zeiss Jena in 1989 Many computer systems have a memory hierarchy consisting of CPU registers, on-die SRAM caches, external caches, DRAM, paging systems, and virtual memory or swap space on a hard drive. This entire pool of memory may be referred to as RAM by many developers, even though the various subsystems can have very different access times, violating the original concept behind the random access term in RAM. Even within a hierarchy level such as DRAM, the specific row, column, bank, rank, channel, or interleave organization of the components make the access time variable, although not to the extent that rotating storage media or a tape is variable. The overall goal of using a memory hierarchy is to obtain the higher possible average access performance while minimizing the total cost of entire memory system. (Generally, the memory hierarchy follows the access time with the fast CPU registers at the top and the slow hard drive at the bottom.) In many modern personal computers, the RAM comes in an easily upgraded form of modules called memory modules or DRAM modules about the size of a few sticks of chewing gum. These can quickly be replaced should they become damaged or too small for current purposes. As suggested above, smaller amounts of RAM (mostly SRAM) are also integrated in the CPU and other ICs on the motherboard, as well as in hard-drives, CD-ROMs, and several other parts of the computer system. Hard Disk A hard disk drive (often shortened as hard disk, hard drive, or HDD) is a non-volatile storage device that stores digitally encoded data on rapidly rotating platters with magnetic surfaces. Strictly speaking, drive refers to the motorized mechanical aspect that is distinct from its medium, such as a tape drive and its tape, or a floppy disk drive and its floppy disk. Early HDDs had removable media; however, an HDD today is typically a sealed unit (except for a filtered vent hole to equalize air pressure) with fixed media. HDDs (introduced in 1956 as data storage for an IBM accounting computer) were originally developed for use with general purpose computers. During the 1990s, the need for large-scale, reliable storage, independent of a particular device, led to the introduction of embedded systems such as RAIDs, network attached storage (NAS) systems, and storage area network (SAN) systems that provide efficient and reliable access to large volumes of data. In the 21st century, HDD usage expanded into consumer applications such as camcorders, cell phones (e.g. the Nokia N91), digital audio players, digital video players, digital video recorders, personal digital assistants and video game consoles. HDDs record data by magnetizing ferromagnetic material directionally, to represent either a 0 or a 1 binary digit. They read the data back by detecting the magnetization of the material. A typical HDD design consists of a spindle that holds one or more flat circular disks called platters, onto which the data are recorded. The platters are made from a non-magnetic material, usually aluminium alloy or glass, and are coated with a thin layer of magnetic material, typically 10-20 nm in thickness with an outer layer of carbon for protection. Older disks used iron (III) oxide as the magnetic material, but current disks use a cobalt-based alloy. The platters are spun at very high speeds. Information is written to a platter as it rotates past devices called read-and-write heads that operate very close (tens of nanometres in new drives) over the magnetic surface. The read-and-write head is used to detect and modify the magnetization of the material immediately under it. There is one head for each magnetic platter surface on the spindle, mounted on a common arm. An actuator arm (or access arm) moves the heads on an arc (roughly radially) across the platters as they spin, allowing each head to access almost the entire surface of the platter as it spins. The arm is moved using a voice coil actuator or in some older designs a stepper motor. The magnetic surface of each platter is conceptually divided into many small sub-micrometre-sized magnetic regions, each of which is used to encode a single binary unit of information. Initially the regions were oriented horizontally, but beginning about 2005, the orientation was changed to perpendicular. Due to the polycrystalline nature of the magnetic material each of these magnetic regions is composed of a few hundred magnetic grains. Magnetic grains are typically 10 nm in size and each form a single magnetic domain. Each magnetic region in total forms a magnetic dipole which generates a highly localized magnetic field nearby. A write head magnetizes a region by generating a strong local magnetic field. Early HDDs used an electromagnet both to magnetize the region and to then read its magnetic field by using electromagnetic induction. Later versions of inductive heads included metal in Gap (MIG) heads and thin film heads. As data density increased, read heads using magnetoresista nce (MR) came into use; the electrical resistance of the head changed according to the strength of the magnetism from the platter. Later development made use of spintronics; in these heads, the magnetoresistive effect was much greater than in earlier types, and was dubbed giant magnetoresistance (GMR). In todays heads, the read and write elements are separate, but in close proximity, on the head portion of an actuator arm. The read element is typically magneto-resistive while the write element is typically thin-film inductive.[8] HD heads are kept from contacting the platter surface by the air that is extremely close to the platter; that air moves at, or close to, the platter speed. The record and playback head are mounted on a block called a slider, and the surface next to the platter is shaped to keep it just barely out of contact. Its a type of air bearing. In modern drives, the small size of the magnetic regions creates the danger that their magnetic state might be lost because of thermal effects. To counter this, the platters are coated with two parallel magnetic layers, separated by a 3-atom-thick layer of the non-magnetic element ruthenium, and the two layers are magnetized in opposite orientation, thus reinforcing each other.[9] Another technology used to overcome thermal effects to allow greater recording densities is perpendicular recording, first shipped in 2005,[10] as of 2007 the technology was used in many HDDs. The grain boundaries turn out to be very important in HDD design. The reason is that, the grains are very small and close to each other, so the coupling between adjacent grains is very strong. When one grain is magnetized, the adjacent grains tend to be aligned parallel to it or demagnetized. Then both the stability of the data and signal-to-noise ratio will be sabotaged. A clear grain perpendicular boundary can weaken the coupling of the grains and subsequently increase the signal-to-noise ratio. In longitudinal recording, the single-domain grains have uniaxial anisotropy with easy axes lying in the film plane. The consequence of this arrangement is that adjacent magnets repel each other. Therefore the magnetostatic energy is so large that it is difficult to increase areal density. Perpendicular recording media, on the other hand, has the easy axis of the grains oriented to the disk plane. Adjacent magnets attract to each other and magnetostatic energy are much lower. So, much highe r areal density can be achieved in perpendicular recording. Another unique feature in perpendicular recording is that a soft magnetic underlayer are incorporated into the recording disk.This underlayer is used to conduct writing magnetic flux so that the writing is more efficient. This will be discussed in writing process. Therefore, a higher anisotropy medium film, such as L10-FePt and rare-earth magnets, can be used. Opened hard drive with top magnet removed, showing copper head actuator coil (top right). A hard disk drive with the platters and motor hub removed showing the copper colored stator coils surrounding a bearing at the center of the spindle motor. The orange stripe along the side of the arm is a thin printed-circuit cable. The spindle bearing is in the center. A typical hard drive has two electric motors, one to spin the disks and one to position the read/write head assembly. The disk motor has an external rotor attached to the platters; the stator windings are fixed in place. The actuator has a read-write head under the tip of its very end (near center); a thin printed-circuit cable connects the read-write head to the hub of the actuator. A flexible, somewhat U-shaped, ribbon cable, seen edge-on below and to the left of the actuator arm in the first image and more clearly in the second, continues the connection from the head to the controller board on the opposite side. The head support arm is very light, but also rigid; in modern drives, acceleration at the head reaches 250 Gs. The silver-colored structure at the upper left of the first image is the top plate of the permanent-magnet and moving coil motor that swings the heads to the desired position (it is shown removed in the second image). The plate supports a thin neodymium-iron-boron (NIB) high-flux magnet. Beneath this plate is the moving coil, often referred to as the voice coil by analogy to the coil in loudspeakers, which is attached to the actuator hub, and beneath that is a second NIB magnet, mounted on the bottom plate of the motor (some drives only have one magnet). The voice coil, itself, is shaped rather like an arrowhead, and made of doubly-coated copper magnet wire. The inner layer is insulation, and the outer is thermoplastic, which bonds the coil together after its wound on a form, making it self-supporting. The portions of the coil along the two sides of the arrowhead (which point to the actuator bearing center) interact with the magnetic field, developing a tangential force that rotates the actuator. Current flowing racially outward along one side of the arrowhead and racially inward on the other produces the tangential force. (See magnetic field Force on a charged particle.) If the magnetic field were uniform, each side would generate opposing forces that would cancel each other out. Therefore the surface of the magnet is half N pole, half S pole, with the radial dividing line in the middle, causing the two sides of the coil to see opposite magnetic fields and produce forces that add instead of canceling. Currents along the top and bott om of the coil produce radial forces that do not rotate the head. Floppy disk A floppy disk is a data storage medium that is composed of a disk of thin, flexible (floppy) magnetic storage medium encased in a square or rectangular plastic shell. Floppy disks are read and written by a floppy disk drive or FDD, the initials of which should not be confused with fixed disk drive, which is another term for a (non removable) type of hard disk drive. Invented by IBM, floppy disks in 8-inch (200mm), 5 ¼-inch (133.35mm), and 3 ½-inch (90mm) formats enjoyed many years as a popular and ubiquitous form of data storage and exchange, from the mid-1970s to the late 1990s. While floppy disk drives still have some limited uses, especially with legacy industrial computer equipment,[2] they have now been largely superseded by USB flash drives, external hard drives, CDs, DVDs, and memory cards (such as Secure Digital). 5 ¼-inch disk had a large circular hole in the center for the spindle of the drive and a small oval aperture in both sides of the plastic to allow the heads of the drive to read and write the data. The magnetic medium could be spun by rotating it from the middle hole. A small notch on the right hand side of the disk would identify whether the disk was read-only or writable, detected by a mechanical switch or photo transistor above it. Another LED/phototransistor pair located near the center of the disk could detect a small hole once per rotation, called the index hole, in the magnetic disk. It was used to detect the start of each track, and whether or not the disk rotated at the correct speed; some operating systems, such as Apple DOS, did not use index sync, and often the drives designed for such systems lacked the index hole sensor. Disks of this type were said to be soft sector disks. Very early 8-inch and 5 ¼-inch disks also had physical holes for each sector, and were termed hard sector disks. Inside the disk were two layers of fabric designed to reduce friction between the medium and the outer casing, with the medium sandwiched in the middle. The outer casing was usually a one-part sheet, folded double with flaps glued or spot-welded together. A catch was lowered into position in front of the drive to prevent the disk from emerging, as well as to raise or lower the spindle (and, in two-sided drives, the upper read/write head). The 8-inch disk was very similar in structure to the 5 ¼-inch disk, with the exception that the read-only logic was in reverse: the slot on the side had to be taped over to allow writing. The 3 ½-inch disk is made of two pieces of rigid plastic, with the fabric-medium-fabric sandwich in the middle to remove dust and dirt. The front has only a label and a small aperture for reading and writing data, protected by a spring-loaded metal or plastic cover, which is pushed back on entry into the drive. Newer 5 ¼-inch drives and all 3 ½-inch drives automatically engages when the user inserts a disk, and disengages and ejects with the press of the eject button. On Apple Macintosh computers with built-in floppy drives, the disk is ejected by a motor (similar to a VCR) instead of manually; there is no eject button. The disks desktop icon is dragged onto the Trash icon to eject a disk. The reverse has a similar covered aperture, as well as a hole to allow the spindle to connect into a metal plate glued to the medium. Two holes bottom left and right, indicate the write-protect status and high-density disk correspondingly, a hole meaning protected or high density, and a covered gap meaning write-enabled or low density. A notch top right ensures that the disk is inserted correctly, and an arrow top left indicates the direction of insertion. The drive usually has a button that, when pressed, will spring the disk out at varying degrees of force. Some would barely make it out of the disk drive; others would shoot out at a fairly high speed. In a majority of drives, the ejection force is provided by the spring that holds the cover shut, and therefore the ejection speed is dependent on this spring. In PC-type machines, a floppy disk can be inserted or ejected manually at any time (evoking an error message or even lost data in some cases), as the drive is not continuously m onitored for status and so programs can make assumptions that do not match actual status. With Apple Macintosh computers, disk drives are continuously monitored by the OS; a disk inserted is automatically searched for content, and one is ejected only when the software agrees the disk should be ejected. This kind of disk drive (starting with the slim Twiggy drives of the late Apple Lisa) does not have an eject button, but uses a motorized mechanism to eject disks; this action is triggered by the OS software (e.g., the user dragged the drive icon to the trash can icon). Should this not work (as in the case of a power failure or drive malfunction), one can insert a straightened paper clip into a small hole at the drives front, there by forcing the disk to eject (similar to that found on CD/DVD drives). Some other computer designs (such as the Commodore Amiga) monitor for a new disk continuously but still have push-button eject mechanisms. The 3-inch disk, widely used on Amstrad CPC machines, bears much similarity to the 3 ½-inch type, with some unique and somewhat curious features. One example is the rectangular-shaped plastic casing, almost taller than a 3 ½-inch disk, but narrower, and more than twice as thick, almost the size of a standard compact audio cassette. This made the disk look more like a greatly oversized present day memory card or a standard PC card notebook expansion card rather than a floppy disk. Despite the size, the actual 3-inch magnetic-coated disk occupied less than 50% of the space inside the casing, the rest being used by the complex protection and sealing mechanisms implemented on the disks. Such mechanisms were largely responsible for the thickness, length and high costs of the 3-inch disks. On the Amstrad machines the disks were typically flipped over to use both sides, as opposed to being truly double-sided. Double-sided mechanisms were available but rare. USB Ports Universal Serial Bus connectors on the back. These USB connectors let you attach everything from mice to printers to your computer quickly and easily. The operating system supports USB as well, so the installation of the device drivers is quick and easy, too. Compared to other ways of connecting devices to your computer, USB devices are incredibly simple we will look at USB ports from both a user and a technical standpoint. You will learn why the USB system is so flexible and how it is able to support so many devices so easily Anyone who has been around computers for more than two or three years know the problem that the Universal Serial Bus is trying to solve in the past, connecting devices to computers has been a real headache! Printers connected to parallel printer ports, and most computers only came with one. Things like Zip drives, which need a high-speed connection into the computer, would use the parallel port as well, often with limited success and not much speed. Modems used the serial port, but so did some printers and a variety of odd things like Palm Pilots and digital cameras. Most computers have at most two serial ports, and they are very slow in most cases. Devices that needed faster connections came with their own cards, which had to fit in a card slot inside the computers case. Unfortunately, the number of card slots is limited and you needed a Ph.D. to install the software for some of the cards. The goal of USB is to end all of these headaches. The Universal Serial Bus gives you a single, standardized, easy-to-use way to connect up to 127 devices to a computer. Just about every peripheral made now comes in a USB version. A sample list of USB devices that you can buy today includes: Printers Scanners Mice Joysticks Flight yokes Digital cameras Webcams Scientific data acquisition devices Modems Speakers Telephones Video phones Storage devices such as Zip drives Network connections In the next section, well look at the USB cables and connectors that allow your computer to communicate with these devices. Parallel port A parallel port is a type of interface found on computers (personal and otherwise) for connecting various peripherals. It is also known as a printer port or Centronics port. The IEEE 1284 standard defines the bi-directional version of the port. Before the advent of USB, the parallel interface was adapted to access a number of peripheral devices other than printers. Probably one of the earliest devices to use parallel were dongles used as a hardware key form of software copy protection. Zip drives and scanners were early implementations followed by external modems, sound cards, webcams, gamepads, joysticks and external hard disk drives and CD-ROM drives. Adapters were available to run SCSI devices via parallel. Other devices such as EPROM programmers and hardware controllers could be connected parallel. At the consumer level, the USB interface—and in some cases Ethernet—has effectively replaced the parallel printer port. Many manufacturers of personal computers and laptops consider parallel to be a legacy port and no longer include the parallel interface. USB to parallel adapters are available to use parallel-only printers with USB-only systems. However, due to the simplicity of its implementation, it is often used for interfacing with custom-made peripherals. In versions of Windows that did not use the Windows NT kernel (as well as DOS and some other operating systems) Keyboard Keyboard, in computer science, a keypad device with buttons or keys that a user presses to enter data characters and commands into a computer. They are one of the fundamental pieces of personal computer (PC) hardware, along with the central processing unit (CPU), the monitor or screen, and the mouse or other cursor device. The most common English-language key pattern for typewriters and keyboards is called QWERTY, after the layout of the first six letters in the top row of its keys (from left to right). In the late 1860s, American inventor and printer Christopher Shoals invented the modern form of the typewriter. Shoals created the QWERTY keyboard layout by separating commonly used letters so that typists would type slower and not jam their mechanical typewriters. Subsequent generations of typists have learned to type using QWERTY keyboards, prompting manufacturers to maintain this key orientation on typewriters. Computer keyboards copied the QWERTY key layout and have followed the precedent set by typewriter manufacturers of keeping this convention. Modern keyboards connect with the computer CPU by cable or by infrared transmitter. When a key on the keyboard is pressed, a numeric code is sent to the keyboards driver software and to the computers operating system software. The driver translates this data into a specialized command that the computers CPU and application programs understand. In this way, users may enter text, commands, numbers, or other data. The term character is generally reserved for letters, numbers, and punctuation, but may also include control codes, graphical symbols, mathematical symbols, and graphic images. Almost all standard English-language keyboards have keys for each character of the American Standard Code for Information Interchange (ASCII) character set, as well as various function keys. Most computers and applications today use seven or eight data bits for each character. For example, ASCII code 65 is equal to the letter A. The function keys generate short, fixed sequences of character codes that instruct application programs running on the computer to perform certain actions. Often, keyboards also have directional buttons for moving the screen cursor, separate numeric pads for entering numeric and arithmetic data, and a switch for turning the computer on and off. Some keyboards, including most for laptop computers, also incorporate a trackball, mouse pad, or other cursor-directing device. No standard exists for positioning the function, numeric, and other buttons on a keyboard relative to the QWERTY and other typewriting keys. Thus layouts vary on keyboards. In the 1930s, American educators August Dvorak and William Dearly designed this key set so that the letters th
