    Charles Xavier Thomas de Colmar invented a calculator that could carry out the four basic mathematical operations (add, subtract, divide and multiply)

  • Jacquard loom machine

    Jacquard loom machine
    Card-controlled artifact in which the gaps were strategically drilled.

  • Babbage Differential Machine

    Babbage Differential Machine
    Designed to work with steam, it was a large machine the size of a locomotive. Function was solving differential equations. During the course of time Babbage began working on the first general purpose computer or analytical machine.

  • First use of programming

    First use of programming
    Lady Ada Lovelace created routine instructions to control the computer, suggested that punch cards could be prepared to repeat certain instructions.

  • Hollerith tabulating machine

  • First Generation (1945-1956)

    First Generation (1945-1956)
    The computer was used for military purposes during World War II.
    IBM created the first electronic calculator in 1944.
    The ENIAC (Electronic Numerical Integrator and Computer), EDVAC (Electronic Discrete Variable Automatic Computer) computer was developed in 1945 and the UNIVAC (Universal Automatic Computer) in 1951.
    The most significant of this generation was the use of vacuum tubes.

  • Second Generation (1956-1963)

    Second Generation (1956-1963)
    The vacuum tubes were replaced by the transistors.
    Machine language was replaced by assembly language.
    High-level languages ​​such as COBOL (Common Business-Oriented Language) and FORTRAN (Formula Translator) were created.
    Smaller, faster and more efficient computers were designed.

  • Third Generation (1964-1971)

    Third Generation (1964-1971)
    Use of silicone chips.
    Operating systems.

  • Fourth Generation (1971-present)

    Fourth Generation (1971-present)
    New chips with greater storage capacity were developed.
    Personal computers and Macintosh began to be used.
    Network design was developed.
    Internet

  • Apple

    Apple
    The Apple I and II computers and Macintosh machines were created in 1984. Personal computers began to be used in offices and homes.
