The Abacus, which emerged about 5000 years ago in asia mirror and us still in use today, and may be considered as the frist computer. This device allows users to make computations using a system of sliding beads arrangsd on a rack.
First mechanical adding machine was invented by Blaise pascal in 1642 Pascal's device used a base of ten to perform calculation. The drawback to the Pascaline, of course, was its limitation to addition
In 1694 a german mathematician and philosopher, Gottfried Wilhem von Leibniz, improved
the Pascaline by creating a machine that could also multiply. Like its predecessor, Leibniz's mechanical multiplier work by a system of gears and dials.
The real beginnings of computers as we know them today, however, lay with an English mathematics professor, Charles Babbage. Charles Babbage is known as father of computers. Babbage developed machine to perfome different equations called Different Engine. It was powered by steam and large as a locomotive, could perform calculations and print the results automatically.
After working on the Different Engine for10 years, Babbage was suddenly inspired to begine work on the frist general purpose computer, which he called the Analytical Engine.
In 1889, an American inventor, Herman Hollerith, also applied the Jacquard loom concept tp computing. Holleriths method used cards to store data or infornation, which he fed into a machine that coropiled the results mechanically.
