Generations of computer

  1. 1. GenerationsofComputer
  2. 2. 5 Generations of Computer• First generation of computer• Second generation of computer• Third generation of computer• Fourth generation of computer• Fifth generation of computer
  3. 3. First generation of computerThe computer of this generation usedelectronic devices known as Vacuum tubesand punched cards to record data.Period : 1940 - 1956Size: Very Huge (Size of 3 rooms)Devices Used: Vacuum TubesExamples: Mark1, UNIVAC-1, EDVAC, EDSAC
  4. 4. Second generation of computerThese computers used transistors in placeof Vacuum tubes.Period: 1957-1963Size: Smaller than first generation ofcomputersDevices Used: Transistors
  5. 5. Third generation of computerIntegrated circuits are made by manyTransistors.Period: 1964-1971Size: Much Smaller than second generationof computersDevices Used: Integrated Circuits
  6. 6. Fourth generation of computerA large number of integrated circuits wereput together in a material called siliconchips. Silicon chips were reliable and cheap.Period: After 1972 to presentSize: Very Small in SizeDevices Used: Silicon Chips
  7. 7. Fifth generation of computerThese computers are based on artificialintelligence. Parallel processing andsuperconductors are used.Period: Present and BeyondSize: Very SmallDevices Used: SuperconductorsExamples: Robots
