Generation Of Computer

Computer Generation

The advancement in hardware technology with the span of time is termed as Computer Generation.

 

First Generation (1951-1959)

Electronic circuitry	Vacuum Tubes
Input	Punched Card
Output	Paper
Storage	Magnetic tape
Example	UNIVACC- I, IBM-650, EDVAC, Mark-II, etc.

 

Second Generation (1959- 1965)

Electronic circuitry	Transistors
Input	Punched Card
Output	Paper
Storage	Magnetic Core Storage
Example	IBM-1400, IBM-7000, SS-80, CDC-160A, etc

.

Third Generation (1965-1971)

Electronic circuitry	Integrated Circuits(IC), LSI
Input	Punched card, Keyboard
Output	Paper, Monitor
Storage	Magnetic Disks, Magnetic tapes
Example	IBM System/360, UNVAC 1108, etc.

 

Fourth Generation (1971- Present)

Electronic circuitry	VLSI
Input	Keyboard, Mouse, Scanner, Digitizers
Output	Paper, Monitor, Plotter, Printer
Storage	Magnetic disk, Optical disk, DVD etc.
Example	IBM System/30, HP-3000, Pentium, etc.
