HISTORY OF COMPUTERS

By luciiaa_fdeezz
  • Period: to

    1ST GENERATION COMPUTERS

    • They were large and expensive, and they needed a lot of energy.
    • They used vacuum tubes (a bulb with wire, used to carry data in form of electrical signals).
    • For example, ENIAC computer (Electronical Numerical Integrator and Calculator).
  • Period: to

    2ND GENERATION COMPUTERS

    • They were faster and cheaper than 1st generation computers.
    • They were smaller.
    • They used transistors.
  • Period: to

    3RD GENERATION COMPUTERS

    • They were faster, smaller and cheaper than 2nd generation computers.
    • They used IC (integrated circuits: they are as small as a transitor but they work as thousand as them).
    • They neede less energy, and they made fewer mistakes.
  • Period: to

    4TH GENERATION COMPUTERS

    • They are confortables and portables.
    • They are samller and cheaper.
    • They make less mistakes.
    • They need less energy.
    • They use microprocessors (a small silicon chip with thousand of circuits).
  • Period: to

    5TH GENERATION COMPUTERS

    • Sciencists are trying to develop them.
    • They are going to think by their own (artificial intelligence).
