Computers we use today do not necessarily appear out of nowhere but through a long process in evolution. Happenings advent of computers may be viewed in a historical flashback from the use of Abacus – are found in Babylon (Iraq) about 5000 years ago – as the first manual calculation tools, both in the scope of the school and among traders, at the time. At a later period have found the means calculating the mechanical type of the Pascaline invented by Blaine Pascal in 1642, Arithometer by Charles Xavier Thomas de Colmar in 1820, Babbage’s Folly by Charles Babbage in 1822, and Hollerith by Herman Hollerith in of 1889. All of which still form the machine completely without electricity. The size and complexity of its structure based on the calculations performed the operation. It was only in 1940, a new era started since the invention of the computer electrically electrical computer system to apply Boolean algebra.
