What is the Generation of Computer 

Generation of computer terminology came, due to frequent changes in the technology of computers.

Each generation of computer is the result of development in technology. Initially, the term generation was used to differentiate between different hardware technologies. but nowadays, generation includes both hardware and software which are very important to building a computer system.

Till date, Total five generations of computers are known and each generation has evolved, due to the gradual advancement in technology and changes in features such as speed, storage capacity, cost, reliability, power consumption, portability, etc.

All these changes in computer technology, have resulted in the development of increasingly more powerful, smaller, cheaper, and more efficient and reliable computer devices.

Let’s learn about the generation of computers –

  • First Generation Computers (1946–1959)
  • Second Generation Computers (1959–1965)
  • Third Generation Computers (1965–1971)
  • Fourth Generation Computer (1971–1980)
  • Fifth Generation Computer (1980 – till now)

First Generation of Computer

Computers from 1946 to 1959 are called first generation computers. Vacuum tubes were used as processors in first generation computers.

The vacuum tube was a drain of glass. First-generation computers produced a lot of heat due to the use of vacuum tubes.

Also, they very large in size, due to this, it was very difficult to maintain them. many people required to operate the first generation computer.

First generation computers used magnetic drums as storage. In this generation of computers, punch cards were used for input and machine language was used as a programming language.

Examples of first generation computers are –

  • IBM-701
  • IBM-650

Second Generation of Computer

Computers from 1959 to 1965 are called second generation computers. In the second generation computers, transistors were used instead of vacuum tubes as processors, which caused the second generation computers to be slightly smaller than the first generation computers. But they were still much larger than today’s computers.

Magnetic cores were used as storage in second generation computers. In this generation of computers, assembly language was used as a programming language because assembly language came in this generation.

Examples of second generation computers are –

  • Honeywell 400
  • IBM 7094
  • CDC 1604
  • CDC 3600
  • UNIVAC 1108

Third Generation of Computer

computers from 1965 to 1971 are called third generation computers. In third generation computers, integrated circuits were used instead of transistors as processors.

The integrated circuit was built by J. S. Kilbi. IC (integrated circuit) is also called LSI (Large Scale Integration).

Fortran, Cobol, BASIC, C, etc. programming languages ​​were invented during the third generation Computer, so Fortran, Cobol, BASIC, C was used as a programming language in third generation computers.

Examples of third generation computers are –

  • IBM 360
  • IBM 370
  • PDP-8
  • PDP-11
  • ICL 2900

Fourth Generation of Computer

Computers from 1971 to 1980 are called fourth generation computers. Microprocessor / VLSI (Very Larg Scale Integration) was used as a processor in fourth generation computers instead of integrated circuits.

Examples of fourth generation computers are –

  • DEC 10
  • PUP 11
  • IBM 4341
  • STAR 1000

Fifth Generation of Computer

Computers from 1980 to now are called fifth generation computers. ULSI (Ultra large scale integration) has been used as a processor in fifth generation computers instead of VLSI (Very large scale integration).

Artificial intelligence came in the fifth generation of computers. The time to come is artificial intelligence. You must have heard the name of Google Assistance. They are also an artificial intelligence like this. Sofia is also an artificial intelligence that is being developed more and more over time.

Examples of fifth generation computers are –

  • Desktop
  • Laptop
  • Notebook
  • Chromebook
  • UltraBook
