A computer is any programmable electronic device that can store, recover, and process data. Moslems developed the basic idea of computing in 1200's when they solved problems with a series of written procedures.
Mechanical calculators were manufactured for sale in the 1640's. There are some records for earlier machines, but Blaise Pascal invented the first commercial calculator. It is a hand powered adding machine. The first true multiplying calculator appeared in Germany shortly before the American Revolution. But, there were some tries to multiply mechanically made by Gottfried Liebnitz in the 1670s.
In 1935, Konrad Zuse, a German construction engineer, built a calculator that worked mechanically. He made it to handle the math involved in his profession. Shortly after completion, Zuse started on a programmable electronic device which he completed in 1938.
In Iowa State, in the basement of the Physics building, John Vincent Atanasoff began work on a digital computer in 1936. A graduate student, Clifford (John) Berry assisted him. The "ABC" was designed to solve linear equations commonly used in physics. It displayed some early features of later computers including electronic calculations. He showed it to the public in 1939(History of Computers).
Nowadays, the uses of computers are limitless. If you look around you, I am sure that you will find a lot of computers nearby. Computers are used in medicine. For example, software is used for performing surgery and is used to store patient data. Also, it is used in mathematical calculations and solving complicated equations that need days to solve. In addition, it is used in the military extensively; pilots are trained in a simulator before going to real flights. Moreover, some planes are piloted by a computer. One important use is the internet where you can access other documents, see your e-mail ….. etc (Dustin Wax). It is very hard to state all computer uses. Finally, this paper is done using a computer.
In conclusion, from what I have been mentioned above we can see there are a lot of people need to use computers because it make their life easeir. Also help and support thim in many feilds in their life.
