The development of V.L.S.I.(Very High Scale Integration) circuits,V.H.S.C.(Very High Speed Integrated) circuits and microprocessor enhanced the performance of fourth generation computers.The first micro processor was developed by American Intel Corporation in 1971.It was called 4004 Micro processor.A Microprocessor is a processor built on a single chip.Today such a microprocessor contain one million transistors.
Compared to previous generations,the fourth generation computer have improved speed, memory size and packing system, C.P.U. and several Input/Output devices are packed into a single chip.Micro computers were introduced during this time.Personal Computers also belonged to this generation.There had been a noticeable development in operating system and application software which made computer user friendly and easy to use.The concept of Supercomputer become a reality.
The examples of Fourth Generation Computers are as follows:
I.B.M. P.C., Apple/Macintosh micro computer, IBM-3080 ETC.
