Brief History Of Computers The history of computers starts out about 2000 years ago‚ at the birth of the abacus‚ a wooden rack holding two horizontal wires with beads strung on them. When these beads are moved around‚ according to programming rules memorized by the user‚ all regular arithmetic problems can be done. Another important invention around the same time was the Astrolabe‚ used for navigation. Blaise Pascal is usually credited for building the first digital computer in 1642. It added
