First Generation Computers – ( 1946-54)
The first generation of computer is marked by the use of vaccum tubes.
Example : – ENIAC, EDSAC, EDVAC.
Second Generation Computers – ( 1954-64)
The second generation of computers is marked by the use of transistors in the place of vaccum tubes.
Example : – IBM 700, ATLAS and ICL 1901
Third Generation of Computers – (1964-80)
The third generation of computers is marked by the use of Integration Circuits ( IC ) in the place of transistors.
Example : – IBM360 Series, Honeywell-6000 Series, IBM-370
Forth Generation Computers – (1980-up to present)
The fourth generation of computer is marked by the use of Very Large Scale Intergrated (VLSI) circuits in the place of integration circuits (IC).
Fifth Generation Computers
The fifth generation computers are under development. Japan and USA have undertaken to design and develop such computers. It appears that the fifth generation computers will have at least three important characteristics: –
Mega Chip Memory
The ability to extensive use of parallel processing, and
Artificial intelligence.
