History of Computers

The idea of ​​computer and history as calculators and computers began to appear the first time in 1822, when the English mathematician Charles Babbage invented the calculating machine called a difference engine. The machine was used to calculate mathematical tables.

Then in 1833, Charles Babbage's difference engine developed again with the concept of a more profound and general. The new machine is called the analytical engine. This machine can perform any calculations, so the engine for the first time this is what is known as a general purpose digital computer.

Charles Babbage's contribution is very large for the computer world today because of the working principle of the two machines is a basic computer work now, including input devices, computer memory, stoed programs and others. Because of this enormous contribution, Charles Babbage considered the father of modern computers.

Then in 1937, Prof.. Howard Aikem, a mathematician from Harvard University and began designing the manufacture of a computer capable of performing arithmetic and logical operations automatically. The first mechanical computer electronics. Then with the help of IBM company, in 1944, the computer is completed electronically. The new computer named "Harvard Mark I Automatic Sequence-Controlled Calculator (ASCC). The computer is this which is a realization of what was envisioned by Charles Babbage. Harvard Mark I computer, when compared with the computer now certainly has a very striking difference, especially in terms of speed.
