 Generation of Computer

Computer generation can be dividing in five generation.

First generation (1945-1955)

·         First generation computer uses Vacuum tubes.

·         Its size was too much large.

·         Slow speed & Lots of Heats.

·         Less storage Capacity.

·         Machine Language (Binary numbers) were used as programming language.

·         Example: - ENIAC, EDVAC, EDSAC, UNIVAC-I etc.

Second generation (1955-1965)

·         Second generation computer uses Transistors.

·         Smaller Size compare to 1^st Generation computers.

·         Less Power Consumption.

·         High storage Capacity compare to 1^st Generation computers.

·         Machine Language as well as Assembly Language were used as programming language.

·         Example: - IBM 1400, 7000 Series, Control Data 3600 etc.

 

 

Third generation (1965-1975)

·         Third generation computer uses Integrated Circuits (IC).

·         Computers smaller, faster, and more reliable.

·         Lower Power Consumption.

·         High Level Language used as programming language.

·         Example: - IBM 360, IBM 370/168, ICL 2900/2903 etc.

Fourth generation (1975-1989)

·         Microprocessor used in Fourth generation of Computer.

·         Computers smaller, faster, and more reliable.

·         LSI, VLSI Technologies Used.

·         High Level Language & 4GL used as programming language.

·         Example: - Pentium (80286, 80386, 80486) P1, P2, P3, P4, P5, dual core, quod core etc.

Fifth generation (1989 - Onward)

·         Microprocessor with ULSI Technologies Used.

·         Computers extremely powerful, very smaller, super faster, more reliable and Portable.

·         Voice Recognition, Parallel Processing Used.

·         Robots and Robotic Devices Used.
