  • 1. GenerationsofComputer
  • 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. 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. Second generation of computerThese computers used transistors in placeof Vacuum tubes.Period: 1957-1963Size: Smaller than first generation ofcomputersDevices Used: Transistors
  • 5. Third generation of computerIntegrated circuits are made by manyTransistors.Period: 1964-1971Size: Much Smaller than second generationof computersDevices Used: Integrated Circuits
  • 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. Fifth generation of computerThese computers are based on artificialintelligence. Parallel processing andsuperconductors are used.Period: Present and BeyondSize: Very SmallDevices Used: SuperconductorsExamples: Robots
