  • The electricity

    The electricity
    The electricity was invented in 1879

  • First generation

    First generation
    The first generation were created between 1942-1955 and used vacuum tubers, for example: ENIAC.

  • ENIAC

    ENIAC
    It weighed 27 tons. It occupied a voom of 167m2 and worked with 17.500 vacuum tubers which could raise the room temperature up to 50ºC.

  • Second generation

    Second generation
    The second generation of computers were created between 1956-1964. They used transistors and they were smaller and cheaper.

  • Third generation

    Third generation
    The third generation computers were created between 1965-1975 and used integrated circuits which works like a hundred of transitors , but are faster and uses less electricity.

  • Fourth generation

    Fourth generation
    The fourth generation of computers were created between 1975 and the present. Uses microproccesors to procces the information faster. They are smaller and pproduce less heat.

  • Fifth generation

    Fifth generation
    The fifth generation will be created in the future and instead of humans, they will use AI (Artificial Inteligence)
