Fourth Generation (1971-1980)
Most computers in use today fall
under this generation of computers, they contain more sophisticated micro
electronic devices and interaction menu. This generation witnessed the
introduction of personal computer, which lead to the demand and the use of computer
system. They users friendly and also rapid growth in the computer Network and
internet.
