  • 500 BCE

    Abacus

    Abacus
    Reduction of size, consumption and heat production. Greater storage capacity and faster speed. Tailored programs By Charles Babbage British mathematician and engineer, basic arithmetic operations were combined with decision processes • The machine had an input and an output unit, using the idea of ​​punch cards
  • 1500

    Clock Calculator

    Clock Calculator
    First mechanical calculator may have been conceived by Leonardo da Vinci around 1502.

  • Pascalina

    Pascalina
    The pascalina was the first calculator that worked on wheels and gears, invented in 1642 by the French philosopher and mathematician Blaise Pascal. The first name he gave his invention was "arithmetic machine." Then he called it "Pascalina wheel", and finally "Pascalina"

  • First Analytical Machinw

    First Analytical Machinw
    The analytical machine is the design of a modern general-purpose computer by the British professor of mathematics Charles Babbage, which represented an important step in the history of computer science. It was first described in 1837, but Babbage continued to refine the design until his death in 1871.

  • First electronic digital computer

    First electronic digital computer
    The instructions were entered by means of perforated tape and the output was obtained in two printers / lists or directly to perforated tape. Half 15 meters. long x 2.4 meters. High

  • First programmable digital computer

    First programmable digital computer
    German engineer Konrad Zuse They were built by means of vacuum tubes. They were programed in machine language The sixth generation could be called the era of smart computers based on artificial neural networks or "artificial brains"

  • First electro-mechanical computer

    First electro-mechanical computer
    Being difficult to determine its exact origin, but at least 3000 years old. The abacus is considered the oldest device used to perform arithmetic operations. "Calculator and electronic numerical integrator" was the first fully electronic digital computer. The Microprocessor appears, the decrease in size, Steves Jobs and A. Wozniak, create the first mass-used microcomputer (1977). Apple is founded.The microcomputers called PC (PersonalComputer) appear

  • ENIAC

    ENIAC
    First mechanical calculating machine, created by "the father of the computer" the mathematical philosopher BlaisePascal It is no longer fundamentally a calculation tool to become primarily a means of communication

  • UNIVAC 1

    UNIVAC 1
    Built on the basis of integrated circuits (LSI) in substitution of the transistor. Decrease in size, reduction of energy consumption, operating systems appear, the concept of Database emerges.

  • 2 Generation Of Computers

    2 Generation Of Computers
    The second generation of computers replaced the vacuum valves with the transistors. That is why the computers of the second generation are smaller and consume less electricity than those of the previous one.

  • 3 generation of Computers

    3 generation of Computers
    In the late 1950s, the invention of the integrated circuit or chip was produced by Jack S. Kilby and Robert Noyce. He then led Ted Hoff to the invention of the microprocessor, at Intel

  • 4 generation of Computers

    4 generation of Computers
    The so-called Fourth Generation is the product of the microprocessor of electronic circuits. The small size of the chip microprocessor made the creation of personal computers possible.

  • 5 generation Of Computers

    5 generation Of Computers
    It arises from the technological advances that were found. ... The fifth generation of computers , also known by its acronym in English, FGCS (from Fifth Generation Computer Systems) was an ambitious project made by Japan in the late 1980s.
