Generation of computers – Computer Knowledge

Ist Generation: (1940-1956)

  • Vacuum tubes got use in circuits.
  • These computers are very large in size.
  • It requires a large amount of electricity.
  • They produce more heat.
  • They are less revival.
  • Ex.: ENIAC, UNIVAC.

IInd Generation: (1957-1962)

  • Vacuum tubes got the replacement by transistors in circuits.
  • Small size as compared to Ist Generation computers.
  • Less amount of heat Generation.
  • Less electricity consumption.
  • Ex.: IBM 350

IIIrd Generation: (1963-1972)

  • Transistors got the replacement by I.C. in circuits. (I.C.- Integrated circuits)
  • Small size as compared to IInd Generation computer.
  • Less amount of heat as compared to IInd Generation computer.
  • Less electricity consumption.
  • Faster and more accurate than the IInd Generation computer.
  • Ex.: IBM 360/370

IVth Generation: (1973-Present)

  • LSI and LSVI technologies are used.
  • LSI- Large-scale integration.
  • LSVI-Very large scale integration.
  • Apple-II, STAR 1000

Vth Generation: (Present & Beyond)

  • It is based on the technique of Artificial Intelligence (AI).
  • The computer can understand spoken words.
  • Scientists are constantly working to increase the processing power of computers.
  • They are trying to create a computer with real IQ with the help of advanced programming and technologies.
  • Ex.: IBM Watson.
