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 to a "textile loom" invented by Joseph Marie Jacquard. Throughout time the idea was taken to a high sort of level. 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 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 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. 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. 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. Firstly communicating with people outside the region of your country. Furthermore, it is cheap, easy, fast, and more accurate. Lastly, it has improved our lifestyle and until this day they are working on extending its features for a better future.
