There were basically three times the computer was mentioned. One as a mechanical computing device, in about 500 BC The other as a concept in 1833, and the third as the modern day computer in 1946. The first mechanical calculator was called the abacus. The abacus is a is a string of moving beads.

The first concept of the modern computer was first outlined in 1833 by the British mathematician Charles Babbage. His outline contained all of todays features in a compute

Early as the 1940's the German Inventor, Konrad Zuse, produced the first operational computer. It was used in aircraft and missile designs, but the German government would not let him improve the machine so it never reached its maximum capability. Two engineers called John W. Mauchly and J. Presper Eckert Jr. from the University of Pennsylvania constructed a calculator. Its construction was an enormous feat of engineering. The 30-ton machine was 18 feet high and 80 feet long, and contained 17,468 vacuum tubes linked by 500 miles of wiring. This calculator performed 100,000 operations per second, and its first operational test included calculations that helped determine the feasibility of the hydrogen bomb.
