Computer Evolution

Posted on Posted in Introduction to Computer

For a long time, scientists, mathematicians, and businessmen have searched for high performance and efficient computing machines.

One of the first tools used. to express numbers was the “Abacus”, developed in “Babylonia” about 5000 years ago. It was built out of wood and beads. The Abacus marked the first step on the road to the computer.

In the early 1600, John Napier, a mathematician from Scotland, invented calculating rods, called Napier’s Bone. This device allowed quick and accurate multiplication of large numbers.

One of the first mechanical calculators was developed about 1642 by Blaise Pascal, “Pascaline”. This machine could process addition and subtraction of numbers and had the ability to carry” digits.

The man who conceived of the computer Was the British inventor “Charles Babbage”. He is considered to be the “Father of modern digital computer”. He developed a calculator called “Difference Engine”. in 1823, Babbage planned to complete another calculating machine “Analytical Engine” but he failed, because technology of that time was not so high but he succeeded in establishing the basic principles on which the modern computers are constructed.
