First Generation Of Computer
The computer of this generation use electronic devices know as Vacuum tubes and Punched cards to record data .

Period : 1940-195
Size : Very Huge (Size of 3 room )
Devices Used : Vacuum Tubes
Examples : Mark1 , UNIVAC-1 ,EDVAC , EDSAC

Second Computer Of Generation

These computers used Transistors in place of Vacuum Tubes .

Period: 1957-1963
Size: Smaller than first generation of computer
Device Used : Transistors

Third Generation Of Computer

Integrated circuits are made by many Transistors.

Period : 1964 - 1971
Size : Much smaller than second generation of computer
Device Use : Integrated Circuits

Forth Generation Of Computer

A large number of integrated circuits were put toghether in a material called Silicon chips . Silicon chips were reliable and cheap .

Period : After 1972 to present
Size : Very small size
Devices Used : Silicon Chips

Fifth generation of computer

These computers are based on artifical intelligence . Parallel processing and superconductors are used .

Period : Present and Beyond
Size : Verry small
Devices Used : Superconducters
Examples : Robots
