  • First generation computer: Vacuum tube are used, from 1940 to 1956.
  • Second generation computer: Transistors are used, from 1956 to 1963.
  • Third generation computer: IC (Integrated Circuits) are used, from 1964 to 1971.
  • Fourth generation computer: Microprocessors are used, from 1971 to Now.
  • Fifth generation computer: Artificial Intelligence CPU, From Now to beyond.
