Grace hopper - Essay Example Because of her personality and a moving effect towards the work that she has done, she was referred to as â€Å"Amazing Grace†. In light of her works, the US Navy destroyer USS Hopper has been named after her. Also the Cray XE6 â€Å"Hopper† supercomputer present at NERSC was named in her memory. Grace Hopper received a PhD in mathematics from the Yale University. She began teaching mathematics at Vassar in the year 1931 and the got promoted to the role of an associate professor 10 years later, in 1941. It was in 1949 that Grace Hopper became an employee of Eckert Mauchly Computer Corporation in the role of a senior mathematician where she came in close collaboration with a team that had the task to develop the UNIVAC I. During the early periods of 1950s, this company was bought out by the Remington Rand Corporation (Richard 1981). This was the time when she was still employed with Eckert Mauchly Computer Corporation that she came up with her original compiler work whic h was a novelty in those times. This compiler was later on named as the A compiler and its initial version was called as A-0. A conference by the name of CODASYL was held in 1959 which brought together computer experts and geniuses from the related industries and the government. Grace Hopper was appointed as the technical consultant of this committee which essentially laid the basis of COBOL. The new language took some of its ideas from the IBM equivalent by the name of COMTRAN. COBOL aimed to write programmes in a language which was more close to the English dictum than the machine oriented basis. This was the reason why COBOL was seen as the single most ubiquitous business language and is still considered so to this day. As a captain in the Navy, Grace Hopper developed a number of validation software for the new programming language (COBOL) as well as its compiler which was a part of the standardization program that went ahead and helped the entire Navy. During her time at the Har vard University in the year 1947, Grace Hopper along with her associates discovered a moth stuck within a relay. After they had done a small operation, Grace Hopper was able to remark this moth as â€Å"debugging† the system. She brought the term of a computer bug to popularity even though she cannot be credited with coining the same. Also, Grace Hopper is famous for her nanoseconds visual aid (Dickason 1992). Since generals and admirals used to quite frequently enquire her about the long extent of time it took for the satellite communications to revert back, she began handing out certain pieces of wire which used to be nearly 1 foot long. This was due to the measurement done on light that it traveled within one nanosecond. She exclaimed that this length of time in nanoseconds was essentially the maximum speed of signals that might travel within vacuum. She also suggested that signals would travel slowly within the wires that were set up on her part as a visual aid. Grace Hop per’s legacy turned out to be quite a popular one for the women. Since Grace Hopper introduced mathematics as a ‘cool’ and trendy subject, it started to come out just like she envisioned within women in different parts of the world. This is the reason why her name is considered as an inspiring factor within the formation of the Grace Hopper Celebration of Women in Computing. This conference is held on an annual basis which brings designers to the fore

International Trade Essay Example | Topics and Well Written Essays - 750 words

International Trade - Essay Example Most of the countries participate in such trades. The US exports high tech goods such as aircrafts, chemicals and ammunitions and at the same time it imports consumer goods, which are traded internationally at much lower prices. Usually, Gross Domestic Product (GDP) and employment has a direct correlation; that is to say, employment or new jobs in the country rises in tandem with the growth in GDP. Gross Domestic Product, in the economic parlance, is the measure of goods and services that are produced in the country. GDP is the sum of the incomes of all the residents within the country. It is also measured by adding all kinds of spending such as government spending, investment spending and consumer spending. All exports generate incomes at home and they are part of GDP. Imports do not form a part of the GDP as they generate incomes abroad. For many years in US, imports exceed exports. That means domestic markets suffer in the goods that are imported. For example, steel import disrupt s domestic steel industry resulting into a closure of many units and the loss of jobs. The government often imposes tariffs on certain products to make imports costlier safeguarding domestic industries. At times, the government resorts to quota system and restricts imports within predetermined quota for a given country. This is usually found in textiles and garments business where quotas are allotted to the countries beyond, which they cannot send material into US. Tariffs restrict international trade as they are one kind of tax on imported good and make imports costlier. The university students in US are not benefitted as consumers of other industrial goods because education industry in US is a big exporter. A huge number of students from other countries enroll in US universities for study and research by paying huge tuition fees in US dollars and spend in US for their essential needs during their learning. Since 1930s, many countries have supported free trade among nations by redu cing tariffs. That is how the process of globalization has progressed at the rapid pace and world trade touched to the tune of almost $12,400 billion by 2009 (International Trade Statistics, 2010 p.12). World Trade Organization (WTO) works toward reduction of tariffs and smooth flow of goods and services among the nations. The WTO also works to discourage retaliatory taxes among nations. When two countries trade their currencies form a relationship for transaction to place. It is true that exchange rates between two currencies are governed by the demand-supply dynamics of the currencies that arise due to trade between two countries. When US imports more Chinese goods and exports less to China, a trade gap also called balance of payments is created causing more demand for Yuan against dollar. When this continues for a long, dollar tends to depreciate against Yuan. In 2011, the US exported goods worth $103.93 billion to China while imported goods worth 399.36 billion creating trade ga p of $295.5 billion. The trade gap was $273 billion and $226.8 billion in the year 2010 and 2009 respectively. The figures reveal that the trade gap is constantly on the rise and the reason for this is that the China produces hosts of goods at much lower the cost compared to the producers in US. The US consumers have benefitted a lot due to these
