THE fourth generation computer (1971 -1990)

These computer were developed during 1971-1990 A. D. The microprocessor brought the fourth generation of computer ,as thousand of integrated circuits were built on to a single silicon chip . What in the first generation generation filled an entire room could now fit in the palm of the hand . the intel 4004chip developed in1971 located all the component of the computer - form the central processing unit and memory input /output control on a single chip . THE MAIN FEATURE OF THE fourth generation computer are: 1. VLSI technology used 2. very cheap 3.portable and reliable 4. use of pc 5. very small in size 6.pipeline processing 7. No A.C needed 8.great development in the field of the network 9.computer became easily available some the computer of this generation are: 1. DEC 10 2. STAR 1000 3. PDP 11 4. CRAY-1-X-MP
