  • PASCALINA

    Blaise Pascal "La Pascalina" It was created in 1642 by the French Blaise Pascal, with the name of arithmetic machine, this invention allowed adding and subtracting 2 numbers directly and doing multiplication and division by repetition,

  • First Generation Computers

    First generation of computers 1938-1958 At this time computers worked with bulbs, punched cards to enter data and programs that used magnetic cylinders to store information, cooling systems were also required that were very expensive, these computers were used in the field scientific and military.

  • Second generation of computers

    Second generation of computers This generation is characterized by the use of the transistor, which sets the standard for information processing, size and reliability, small magnetic rings were also used to store information, these computers continued to produce a large amount of hot and they were also slow.
    At this time, new programming languages such as "COBOL" and "Fortran" were also developed, which were used in airline systems and air traffic control.

  • Third generation of computers

    Third generation of computers In this generation, integrated circuits begin to be used, these consist of packing hundreds of transistors, in a thin silicon chip, which allows to lower costs, at the same time that the processing capacity is increased and reduced the size of the machines.

  • Fourth generation of computers

    Fourth generation of computers This generation is characterized by the use of the microprocessor, that is, a single integrated circuit in which the basic elements of the machine are brought together, more circuits are also placed within a single chip, each chip performs different functions, and replaces ring memory with silicon chip memory.

  • Fifth generation of computers

    Fifth generation of computers This generation allowed the user to communicate with the computer in a simpler way, through an everyday language and not through codes, computers were manufactured with the ability to work simultaneously with several processors and recognize voice and images.
    Another advance was the way information is stored.
