The Simple Computer POST Power on self-test (POST) is a test which the computer completes on start-up which will verify whether the hardware is all working correctly. If the hardware is working correctly the computer will continue to boot if not a beep code is generated. A BIOS may have a different beep code depending on what type of BIOS it is.

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]
