A computer is a machine that is able to take information (input)‚ do some work on or make changes to the information‚ to make new information (output). Computers have existed for much of human history. Examples of early computers are the astrolabe and the abacus. Modern computers are very different from early computers. They are now very powerful machines that are able to do billions of calculations every second. Most people have used a personal computer in their home or at work. Computers are

Date | Event | c. 2400 BC | The abacus - the first known calculator‚ was probably invented by the Babylonians as an aid to simple arithmetic around this time period. This laid the foundations for positional notation and later computing developments. | 1300 | Ramon Llull invented the Lullian Circle: a notional machine for calculating answers to philosophical questions (in this case‚ to do with Christianity) via logical combinatorics. This idea was taken up by Leibniz centuries later‚ and is thus

HISTORY OF COMPUTERS Ancient era Suanpan (the number represented on this abacus is 6‚302‚715‚408) Devices have been used to aid computation for thousands of years‚ mostly using one-to-one correspondence with fingers. The earliest counting device was probably a form of tally stick. Later record keeping aids throughout the Fertile Crescent included calculi (clay spheres‚ cones‚ etc.) which represented counts of items‚ probably livestock or grains‚ sealed in hollow unbaked clay containers.[1][2]
