History of computers

  • Charles Babbage announces the analysis machine

    Charles Babbage announces the analysis machine
    Its general purpose was a machine that could be programmed by the user, capable of executing the desired instructions and commands.
  • Period: to

    First generation

    First generation computers used vacuum tubes. A vacuum tube is a device that controls electric current flow in a high vacuum betwee electrodes to which an electric potential difference has been aplied.
  • They started building ENIAC

    They started building ENIAC
    Germans started to build the ENIAC.
  • ENIAC was finished

    ENIAC was finished
    The first computer in the world was finished.
  • Period: to

    Second generation

    The second generation of computers consists of two types of devices, transistors, and magnetic core. The transistors helped to develop a better computer than the first generation computers consisting of vacuum tubes. They were smaller and cheaper to create.
  • Period: to

    Third generation

    The computers of the third generation used integrated circuits (IC) instead of transistors. They were more reliable, even smaller in size and the consumed less electricity. They were invented by Jack Kilby.
  • Period: to

    Fourth generation

    These computers used microprocessors instead of IC. These computers were very compact and thereby required a very small amount of electricity. This generation of computers had the first ''supercomputers''.
  • Fifth generation (AI)

    Fifth generation (AI)
    Its objective was the development of a new class of computers that would use artificial intelligence techniques and technologies
