After 1971 the fourth generation computers were built. The fourth generation computers were the
extension of third generation technology. The fourth generation computers emerged with developm-
ent of the VLSI (Very Large Scale Integration).With the help of VLSI technology microprocessor
came into existence. The computers were designed by using microprocessor, as thousands of integr-
ated circuits were built onto a single silicon chip. What in the first generation filled an enti-
re room could now fit in the palm of the hand. The fourth generation computers became more powerful,
compact, reliable and affordable. As a result, they give rise to personal computer (PC) revolution.
For the first time in 1981 IBM introduced its computer for the home user and in 1984 Apple introduc-
ed the Macintosh Microprocessor.

CHARACTERISTICS
1) The fourth generation computers have microprocessor-based systems.
2) They are the cheapest among all the computer generation.
3) The speed, accuracy and reliability of the computers were improved in fourth generation computers.
4) Many high-level languages were developed in the fourth generation such as COBOL, FORTRAN, BASIC,
   PASCAL and C language.
5) A Further refinement of input/output devices was developed.
6) Networking between the systems was developed.

IBM 4341, DEC 10, STAR 1000, PUP 11 and APPLE II are the examples of fourth generation computers.
