Data Storage Technology Options for Business Need Essay

Data Storage Technology Options for Business Need - Essay Example For computer systems technology to cope with these intensifying storage and processing needs, the demand for performance and storage capacity has risen acutely. This has contributed to the manufacture, invention, and uses of a variety of physical storage devices for computer systems. These physical storage mediums in the contemporary computing world range from the familiar usual floppy disk, hard disk, flash drive, DVDs and CD-ROMs, and tapes that are commonly used in Information Communications Technology business and organization sectors. It’s also important to note that these storage devices have different file allocation methods and size allocation. This is therefore what is going to form the discussion basis of this paper. Additionally, this paper will also evaluate the concept of fragmentation of file systems on the storage devices and how best they could be managed (Parsons & Oja, 2009). The computer storage devices are divided into three major classes including Magnetic , Optical, and Semiconductor. Computer storage systems are also widely referred to as secondary storage media or devices. Magnetic storage devices basically record and store information in the form of magnetized spots. These magnetized spots are represented by binary codes with a magnetized head that slightly hangs freely above the surface of the storage device that reads and records information by use of electric charges. The data hence can be retained, erased or replaced by the use of new magnetic spots. Examples of magnetic storage include the Tape, referred to as magnetic tape that is used to read, write and store information up to a terabyte. They are generally used in magnetic tape recorders or machines to record and write data after which the tapes can be connected to gadgets that can read the  information.

Comment critically on comparative advantage as a basis for international trade Essay Example for Free

Comment critically on comparative advantage as a basis for international trade Essay Comparative advantage was an idea proposed by David Ricardo in 1817, and is an idea which can be used on a variety of scales, but is most often used when analysing international trade. Ricardo used the idea of wool produced in England at a lower opportunity cost than wool is produced in Portugal relative to wine, while in Portugal wine is produced at a lower opportunity cost than wine is produced in Britain relative to the wool. This means that in Portugal it is less costly to produce wine in terms of what is the next best use of the resources involved. The reasons that this occurs could be for any number of reasons: weather, technology, productivity of workers in that industry and so on. This idea is one that all countries can benefit from, as even a tiny country will have a comparative advantage in a good relative to another good, even when trading with a world superpower. Comparative advantage is often used to look at just two countries and two goods, which is not necessarily a pitfall as the model can be applied to multiple countries and multiple goods, it is just for simplicity. Shown below is a very simple idea of the benefits produced by comparative advantage: As with any model in economics, comparative advantage is not ideal. It is a proposed model based upon a fundamental idea which has very often proved itself to be true, but it still relies on many ideals and factors that do not and cannot realistically exist. These underlying assumptions mean it is difficult to base international trade upon the comparative advantage theory. However, the comparative advantage theory is questionably a solid basis to trade, even if it cannot explain international demand and supply in its entirety. The biggest problem when it comes to how affective comparative advantage is in dictating trade is that all factors of production are assumed to be perfectly mobile, something which it is fair to say is never the case. The idea is that any factors of production, be it labour, capital, land or entrepreneurship, that these, if made redundant from one industry it is thought that these resources could immediately be transferred to another industry that has a comparative advantage over the other country. This is clearly not going to be case, unless the industries are very similar, something which contradicts another theory of comparative advantage, which states all goods are homogenous. It is therefore almost an impossibility for this to occur, for the unemployment created by a failed industry to be suddenly removed by another. Structural unemployment of people without the necessary skills to work, is inevitable. Even in the EU, where the S.E.A single market was set up in 1986, it is still difficult just to go and work in another EU country for geographic, structural and lingual reasons. The government would have to spend a huge amount on supply side policies such as very efficient schemes of education or perhaps low taxation (Thatcherite) to be able to transfer skills that quickly, and shift the long run aggregate supply curve to the right, thus reducing unemployment: Because the government realises just how unlikely and difficult it is to transfer resources, it actively discourages the failure of an industry, as shown by the EUs enormous subsidies of the farmers in this country, most notably the Common Agricultural Policy. It is therefore acting against the theory of comparative advantage, as this would dictate that the farmers move into the service sector, where Britain is very productive. This shows how politics has a great affect on trade once the industry has been established, though comparative advantage may well have dictated what industries were originally started and how they grew, even if politics has a greater effect today. The fact that politics makes a big difference in the effect of comparative advantage demonstrates another shortcoming of the theory. It assumes that trade around the world is completely free, something which is increasingly true, although the creation of the EU has meant that trade within the EU is almost completely free, while from in the EU to the rest of the world, protectionist policies are in place. There also continue to be some semi-autarkic countries such as North Korea. If cricket bats are made in both England and Pakistan, if Pakistan has the comparative advantage in making the good, in terms of Panama hats for example, consumers in the UK may well still buy cricket bats from British producers, for several reasons, most importantly that policies such as tariffs or quotas may well be in place on goods entering the EU, in which case the goods are no longer price competitive. This is shown below: However, the large sales of cricket bats in the UK may well also be for other reasons. Cricket bats are not a homogenous product, with different bats suiting different players, and other non-price competitive reasons such as a higher quality of bat made domestically or that there is better after-sale support. This is something that the theory of comparative advantage does not take into account. It may also be very expensive to transport the bats to the UK from Pakistan, making it no longer economically efficient to trade here. This is something else that is not taken into account by the model. All these things aside, the reasons why countries trade is for the benefits that arise from the trading, such as specialisation increasing output, economies of scale, innovation through competition and the welfare gains in increasing the consumers choice. It is at no stage a random process as to what goods are traded, and there are good reasons for why bananas arent grown in England and sheep arent reared in the West Indies. The productivity of a country in producing a good dictates what it will trade, and a country that is very inefficient in producing a good will move onto something to which it is more suited. There are of course cases where this is overridden by the factors mentioned, but ultimately comparative advantage theory does form a basis as the title suggests, to almost all international trade. For the trade to occur, the terms of trade are laid out, which is simplified to compromising between the opportunity cost ratios of the two countries. Once again, this is not exactly how it works, as politics and economics merge to create something slightly different, but it is highly likely to be something close to what comparative advantage suggests it should be. It is inevitable that the model does not fit the real world, but there is not a single economic theory that can be applied directly to an economy with no assumptions being made.

Education Today Essay -- essays papers

Education Today A college education is suggested to be the most heavily judged form of qualification to be looked at when looking for career opportunities. But what is a college education? Is it something you go out and buy at the most prestigious of College University's? Do you simply hand over 25,000 dollars a year, and at the end of 4 years, give or take a few, you are handed a diploma that says, 'Educated'? In my opinion, this is today's view on what education is. It is less of a conquest of knowledge then it is just a stepping-stone towards a career. John Newman suggested that all forms of education and knowledge are connected together, and that the subject matter of knowledge is united in itself. Each Science that we break our knowledge in to, complete, correct and balance the others. This is what John Henry Newman wrote in, The Idea of a University. This was written to discuss the idea of a Catholic University, so it has a large influence on how we get our education today. We take specific courses that educate us in our major, and a number of other core courses that help shape our ideas and views into that which we are learning. If an education is confined to only one subject, Newman believes the individual's work in life may favor the advancement of a particular pursuit or viewpoint over another, due to ignorance. This is the approach we take at Seton Hall and most other University's in the world towards an education. But is this the only form of education that is valid? Jon Spayde believed that one could gain education in any way he wants. If biology was an individual's serious interest, he could observe life throughout the year and justifiably educate himself that way. Anything you had int... ...roader the education you get the more knowledgeable you will become in all areas of your study. However, I also think that it isn't necessary to pay for a college degree to be truly educated. The problem is you have nothing to show for or prove your intellect. In today's competitive society everyone wants the best, and if you don't complete a college education and have your own individual flares your going to have a much harder time landing a job then perhaps someone you are smarter then. You can't just be the best, you have to show that you are the best. It seems that if you can throw 100,000 dollars away on a degree today, you probably will have a decent job waiting for you when you graduate. So the individual with the advantage in society is the one who loves what he paid to get educated in. Education in a field that you love is the only true conquest of knowledge.

Disease Prevention Measures among African Americans Living in the United States Essay

My research explores race-based medicine. Specifically, my research will focus on what preventative measures are available for African American women living in the United States. Among minorities African American women have a higher number of health disparities; psychological and disease oriented. What percentages of minorities take advantage of preventative medicine? What percentage of African Americans are aware of resources made available to them? The growing number of obesity related diseases among African American women has increased more than 23% from 2010 (Nickens, H.W., 2006). Failure to use preventative measures has sparked much concern surrounding the implications and scientific evidence of race-based medicine. Race-based medicine focuses on the current system of public health services because now more than ever. Due to the increasing number of deaths within the African American community there is an expectation from the larger medical community on how to improve medical services that will work more efficiently for African American women. The concern about preventative measures among minority groups focuses on three things; 1) that it meets the needs of the individual, 2) that the service will be free at point of delivery and 3) that once service is received the individual will continue to utilize the service which will increase preventative measures for African American women. Preventative measures of obesity related diseases for African American women are lacking in several areas. Awareness about health systems and services offered are sometimes misinterpreted and therefore discourages African American women to utilize health information and facilities offered to the general public.

Welsh History essays

Welsh History essays Wales has a tumultuous and somewhat violent history. During the early years A.D., the country was in turmoil with the Roman invasions, and the biggest defenses that the Welsh had were the deep, dark hills scattered all over the country. Without the safety of these hills, Wales would certainly have been taken over by the Romans. After the Romans left Wales, the Vikings presented a new threat to the peaceful lands of Wales. The Romans also had a huge effect on the Welsh religion and language. Wales was affected both negatively and positively by these invasions. In 55 B.C., Julius Caesar planned a series of exploratory expeditions into Wales, which were inspired by tales of large deposits of gold in the vast hills in North Wales. (Millet, 1995, p.187) These explorations prepared the ground for the arrival of the Roman armies (Cunliffe, 1990, p.203). In 43 A.D., the Roman army arrived on the shores of Wales to attempt a completion of their new Roman British empire (Tedesco, 178, p. 387). Wales had a strong military history that took a central role in society as far back as 1200 B.C. (Thompson, 1989, p.735). The old Roman boast Veni, Vidi, Vici (I came, I saw, I conquered) might have been applied to other places in their vast empire, but in Wales, their conquest was never complete (Johanson, 1979, p. 359). To help with the invasion, they constructed a city at Caerwent that introduced Roman notions of civilization to the natives. They also built a network of roads that connected their two bases at Chester and Caerwent with some small forts (Av ery, 1975, p.687) During some expeditions into the hills of Pumpsaint, the Romans finally found the gold that they had been searching for (McQueen, 1985, p.982) When the Romans left Wales in the 4th century, they left it unprotected against the Saxons, Picts and Irish Goidel tribes. The end of the Roman Empire meant the beginning of a Dark Age for Wales ( ...

The Marshall Plan

The Marshall Plan Initially announced in 1947, the Marshall Plan was a U.S.-sponsored economic-aid program to help Western European countries recover following World War II. Officially named the European Recovery Program (ERP), it soon became known as the Marshall Plan for its creator, Secretary of State George C. Marshall. The beginnings of the plan were announced on June 5, 1947, during a speech by Marshall at Harvard University, but it wasn’t until April 3, 1948, that it was signed into law.  The Marshall Plan provided an estimated $13 billion in aid to 17 countries over a four-year period. Ultimately, however, the Marshall Plan was replaced by the Mutual Security Plan at the end of 1951. Europe: Immediate Post-War Period The six years of World War II took a heavy toll on Europe, devastating both the landscape and the infrastructure.  Farms and towns were destroyed, industries bombed, and millions of civilians either killed or maimed.  The damage was severe and most countries didn’t have enough resources to help even their own people. The United States, on the other hand, was different.  Because of its location a continent away, the United States was the only country that did not suffer major devastation during the war and thus it was to the U.S. that Europe looked for help. From the end of the war in 1945 until the beginning of the Marshall Plan, the U.S. provided $14 million in loans. Then, when Britain announced that it could not continue to support the battle against communism in Greece and Turkey, the United States stepped in to provide military support to those two countries. This was one of the first actions of containment outlined in the Truman Doctrine. However, recovery in Europe was progressing much slower than initially expected by the world community.  European countries compose a significant segment of the world economy; therefore, it was feared that the slow recovery would have a ripple effect on the international community.   Additionally, U.S. President Harry Truman believed that the best way to contain the spread of communism and restore political stability within Europe was to first stabilize the economies of Western European countries who had not yet succumbed to communist takeover.   Truman tasked George Marshall with developing a plan to carry out this goal. Appointment of George Marshall Secretary of State George C. Marshall was appointed to office by President Truman in January 1947.  Prior to his appointment, Marshall had an illustrious career as the chief of staff of the United States Army during World War II. Because of his stellar reputation during the war, Marshall was viewed as a natural fit for the position of secretary of state during the challenging times that followed.   One of the first challenges Marshall faced in office was a series of discussions with the Soviet Union regarding the economic restoration of Germany.  Marshall could not reach a consensus with the Soviets regarding the best approach and negotiations stalled after six weeks.  As a result of these failed efforts, Marshall elected to proceed with a wider European reconstruction plan. The Creation of the Marshall Plan Marshall called upon two State Department officials, George Kennan and William Clayton, to assist with the construction of the plan.   Kennan was known for his idea of containment, a central component of the Truman Doctrine.  Clayton was a businessman and government official who focused on European economic issues; he helped lend specific economic insight into the plan’s development. The Marshall Plan was crafted to provide specific economic aid to European countries to revitalize their economies by focusing on the creation of modern post-war industries and the expansion of their international trade opportunities.   Additionally, countries used the funds to purchase manufacturing and revitalization supplies from American companies; therefore fueling the American post-war economy in the process.   The initial announcement of the Marshall Plan occurred on June 5, 1947, during a speech Marshall made at Harvard University; however, it did not become official until it was signed into law by Truman ten months later.   The legislation was titled the Economic Cooperation Act and the aid program was called the Economic Recovery Program. Participating Nations Although the Soviet Union was not excluded from participating in the Marshall Plan, the Soviets and their allies were unwilling to meet the terms established by the Plan.  Ultimately, 17 countries would benefit from the Marshall Plan.  They were: AustriaBelgiumDenmarkFranceGreeceIcelandIrelandItaly (including the Trieste region)Luxembourg (administered jointly with Belgium)NetherlandsNorwayPortugalSwedenSwitzerlandTurkeyUnited Kingdom It is estimated that over $13 billion dollars in aid was distributed under the Marshall Plan.  An exact figure is difficult to ascertain because there is some flexibility in what is defined as official aid administered under the plan.  (Some historians include the â€Å"unofficial† aid which began after Marshall’s initial announcement, while others only count aid administered after the legislation was signed in April 1948.) Legacy of the Marshall Plan By 1951, the world was changing. While the economies of Western European countries were becoming relatively stable, the Cold War was emerging as a new world problem. The rising issues related to the Cold War, particularly in the realm of Korea, led the U.S. to rethink the use of their funds.   At the end of 1951, the Marshall Plan was replaced by the Mutual Security Act.  This legislation created the short-lived Mutual Security Agency (MSA), which focused not only on economic recovery but also more concrete military support as well.  As military actions heated up in Asia, the State Department felt that this piece of legislation would better prepare the U.S. and its Allies for active engagement, despite the public mindset that Truman hoped to contain, not combat communism. Today, the Marshall Plan is widely viewed as a success.  The economy of Western Europe rebounded significantly during its administration, which also helped to foster economic stability within the United States. The Marshall Plan also helped the United States prevent the further spread of communism within Western Europe by restoring the economy in that area.   Concepts of the Marshall Plan also laid the foundation for future economic aid programs administered by the United States and some of the economic ideals that exist within the present European Union. George Marshall was awarded the 1953 Nobel Peace Prize for his role in creating the Marshall Plan.
