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]

➢ What is a computer? Why it is also known as a data processor? A device that computes‚ especially a programmable electronic machine that performs high-speed mathematical or logical operations or that assembles‚ stores‚ correlates‚ or otherwise processes information is known to be a computer. A computer is an electronic device which manipulates or transforms data. It accepts data‚ stores data‚ process data according to a set of instructions‚ and also retrieve the data when required. Hence it is
