And come to us a modern computer.It has Very lower  power cost and Very small size more effective use full.The Intel 4004 chip made in 1971.This time big advantage of computer that data shearing another Coputer that means networking.Two type of networking has famous. number one LAN (Local area network) and number Two WAN (Wide area network)In 1981, IBM introduced personal computers for home and office use.
