    Adding machine

    Adding machine
    It was a mechanical adding machine invented between the years 1452-1519.

  • The Pascaline

    The Pascaline
    It was the first calculator to work on wheels and gears, invented in 1642 by the French philosopher and mathematician Blaise Pascal (1623-1662). The first name he gave to his invention was 'arithmetic machine'. Then he called it "pascaline wheel", and finally "pascaline". This invention is the remote ancestor of today's computer.

  • Mark 1

    Mark 1
    The IBM Automatic Sequence Controlled Calculator (ASCC), better known as the Harvard Mark I or Mark I, was the first electromechanical computer, built at IBM and shipped to Harvard in 1944. It had 760,000 wheels and 800 kilometers of cable and was based on the machine. analytics by Charles Babbage.

  • ENIAC

    ENIAC
    ENIAC, an acronym for Electronic Numerical Integrator And Computer, was one of the first general-purpose computers. Engineers John Presper Eckert and John William Mauchly took the credit for the construction, but it was six women who programmed it: Betty Snyder Holberton, Jean Jennings Bartik, Kathleen McNulty Mauchly Antonelli, Marlyn Wescoff Meltzer, Ruth Lichterman Teitelbaum and Frances Bilas Spence.

  • Atlas 1962

    Atlas 1962
    it was a supercomputer model jointly designed by the University of Manchester and the Ferranti and Plessey companies. When the first Atlas was put into operation at the University of Manchester in 1962, it was one of the first supercomputers, and the fastest until the CDC 6600 hit the market.

  • IBM S/360

    IBM S/360
    It was a mainframe family computer system, which IBM announced on April 7, 1964. It is characterized by the revolutionary appearance of integrated circuits (chips) made from silicon.

  • IBM PC

    IBM PC
    Commonly known as the IBM PC, it is the original version and the progenitor of the IBM PC compatible hardware platform. It is the IBM model 5150, and it was introduced on August 12, 1981 as part of the fifth generation of computers. It was created by a team of engineers and designers under the direction of Don Estridge and William C. Lowe of the IBM Entry Systems Division in Boca Raton, Florida.

  • Fifth generation (1985-present)

    and this is technically what we have today
