Generation of Computer

Following generations of computers

First Generation 1942–1955

The first generation computer used a vacuum tube. The vacuum tube was large in size, so the computers of this generation were very large. The speed of working of computers of this generation was also very slow

In the first generation computers, magnetic drums were used for memory and worked on machine language (0,1).

UNIVAC 1, ENIAC, and Mark 1 are examples of first generation computers



Second Generation 1955–1964

Solid state transistors were used in place of vacuum tubes in second generation computers. In this generation high-level programming languages ​​were developed, such as BASIC, COBOL, FORTRAN etc.

IBM-70 Series, IBM-1400 Series, IBM-1600 Series, HONEYWELL-400 to 800

Series, CDC-3600 etc. were some of the major computers of this generation.

Third Generation 1965-1974

Integrated circuits were replaced by transistors in computers of this generation. IC (IC) is also called. The invention of IC s. Done by kilby

In this generation of computers, high level language was used for programming. In this, magnetic disks were used as memory.

Important computers of this generation were IBM-360, ICL-1900, IBM-370, VAX-750 etc.

Fourth Generation Since 1975

Ultra-Scale Integrated Circuits – ULSI were used in computers of this generation. In this high-level language is used for programming.

Fifth Generation

These computers are still in development stage. The technology of Artificial Intelligence is being used in these computers.
