Computer is one of the top inventions in the world

The computer can not be top without 2 other key inventions. Alternating Current generators and solid-state electronics. Mechanical computers have been around since the abacus and a mechanical tax tabulator created by Pascale. Those and Vacuum tubes created the first Uni-Vac systems, but they still need the raw power of AC. The components got smaller with the invention of solid-state electronics. All the "1"s and "0"s used in computer is based on the concept of polaroty changes from on to off electronically.
