  • First Mechanical Calculator

    First Mechanical Calculator
    Also known as the Calculating Clock, and created by Wilhelm Schickard. It could add and substract up to six-digit numbers.
  • Period: to

    Mechanical Era

    The beginnings of computers. They were able to do basic operations.

  • The Punched Card

    The Punched Card
    Joseph-Marie Jacquard created a loom which followed the instructions of a punched card, which is a perforated piece of cardboard in a specific order that can be interpreted by a machine. They could be changed by other cards without altering the loom.

  • Difference Engine

    Difference Engine
    Created by Charles Babbage. Considered the first computer, it could calculate functions automatically.

  • First Computer Algorithm

    First Computer Algorithm
    It was made by Ada Lovelace, one of the most important figures in computer's history. She explained how could machines be coded with a method of instruction repetition. Her work was not taken into account until less than a century ago.

  • Turing Machine

    Turing Machine
    Made by Alan Turing. It's an hypothethical machine which with a strip of tape with squares on it, and it could follow any possible algorithm. It could read and write on the squares following its programmation.
  • Period: to

    First Generation

    First electronic computers.

  • ENIAC

    ENIAC
    First computer for general use. It was really big and complex, and could do several types of calculations.
  • Period: to

    Second Generation

    Vacuum valves are replaced by transistors.

  • FORTRAN (First Computer Language)

    FORTRAN (First Computer Language)
    It was used for scientific and engineering calculations thanks to its ability to calculate numbers and to make scientific computations.
  • Period: to

    Third Generation

    The first integrated circuits were manufactured.

  • Intel-4004 (First Microprocessor)

    Intel-4004 (First Microprocessor)
    The Intel-4004 revolutioned the market. CPUs are nowadays the main brain of all our computers.
  • Period: to

    Fourth Generation

    First microprocessors were made, and PCs started to appear.
  • Period: to

    Fifth Generation

    Artificial Intelligence started to develop. In development nowadays.

  • WiFi

    WiFi
    This helped and keeps allowing computers and other devices to connect between each other without a wire.
