Roughly 9000 years ago when some guy out for a walk tripped over one and said "Ouch, I just discovered the abacus! Too bad I don't know what an abacus is or if it even has a use. It doesn't even look pretty. The beads are just plain wood so no use taking it apart for them as my girl wouldn't like them." He then threw it over his shoulder, rubbed his sore toe until it felt better and resumed his walk.
Of course the above story is all nonsense as mechanisms like the abacus are invented or designed, not discovered. However the date of 9000 years ago for the first one being made is not unreasonable, as most early cultures that used the abacus developed it long before developing writing or even oral history. Therefor we have no record of its invention.
The abacus was developed by the Babylonians in 2000 BC. Though mechanical, it is considered to be one of the earliest computers.
China invented the abacus .
No single person discovered computers; computer technology in general evolved over time (since the abacus) to what it is today.
No, it is a simple mechanical device used for calculation and was invented about 4000 years before humans discovered electricity.
