Early computing machines(Mechanical) about 3000 BC - The abacus is invented,probably in Babylonia

1941- Konrad Zuse builds the Z3 computer, the first calculating machine with automatic control of its operations

By 1947, the invention of the transistor greatly changed the computers developement.The transistor replaced the large,unpractical vacuum tube in computers. Computers came smaller,faster,more reliable and more energy- efficent

Integrated circuits semiconductor devices with several transistors built into one physical component.Texas Instrument and Fairchild both announce the integrated circuit 1959

Intel 4004 chip took the integrated circuit one step further by locating all the components of a computer on silicon chip.Whereas previously had manufactured to fit a special purpose, now one microprosessor could be manufactured and programmed to meet any number of demands.Other Intel prosessors 8008, 8086, 80286, 80386, 80486, pentium, pentium pro,pentium II,pentium III and pentium IV.
