Final draft

The development of the modern day computer was the result of advances in technologies and man's need to quantify information. The word computer referred once to a person who used to do calculations and computations in his head. During the 20th century, that particular word was referred to a developed machine, which carried out all sorts of computations. It began from a "castle clock" invented by Al Jazari (http://www.muslimheritage.com/topics/default.cfm?ArticleID=899) to a "textile loom" invented by Joseph Marie Jacquard (http://www.ideafinder.com/history/inventions/jacquard.htm). Throughout time the idea was taken to a high sort of level. Wilhelm Schickard's 1623 device was the first of a number of mechanical calculators constructed by European engineers, but none fit the modern definition of a computer, because they could not be programmed (http://en.wikipedia.org/wiki/computer). Also the American scientist Vannevar Bush built a mechanically operated device, called a differential analyzer, in 1930; it was the first general-purpose analog computer http://www.infoplease.com/ce6/sci/A0857507.html. Until it reached to this improved device you see in most households and work places. Computers arose in the 1970s. They are the widest spread technology in the world. Computers have become indispensable in today’s world. Millions of people use computers all over the world.Computers have been a great help, especially in work places. For example, before employees used to handle a lot of paper work some papers get lost and some ruined, and even some get stolen. Computers have changed that, now all an employee has to do is type in data into a certain system where it can be saved. This way it cannot be tampered with and it would be very easy to find. It saves the employees and the computers so much time. Moreover, internet accomplished a lot of jobs where you browse through more information than you can do in libraries in which computers can store enormous amount of information. Although the internet has enabled a lot of people to study other people's culture and traditions in several ways; one major way is the chatting software which enables one to chat with an other person in a fast way; emails also help you to communicate with a person sitting thousands of miles away from your home and are used nowadays in paying bills and sending forums.
Computers have developed and changed a lot of things in business. For example, computer software is used in shops and supermarkets for calculating bills, loans and bills can be paid, trades also can be done online. It has been so very important that even companies pay a lot of money to make their workers take a course in ICDL, which is the study of how to use a computer, as do most of the universities. Even old people I know take that test, because they are curious. They want to know how it works and what it does, which I find very exhilarating! The computer has organized simple procedures. Computers have taken the human society into a higher league. It is used in each and every aspect of human life. Nowadays it is difficult to imagine a home without a computer or internet. Computers are cheap, easy, fast, and accurate. They have improved our lifestyle and until this day they are working on extending their features for a better future.
