History of computer

  • IBM

    Herman Hollerith, an American inventor, built a machine to count a census. It used punched cards and gears like the previous ones, but it worked with electricity. His company grew to become the first computer manufacturer in the world: IBM.

    The first computer called ENIAC is introduced to the public. It was built at the University of Pennsylvania (USA) and operated with more than 17,000 vacuum tubes. It could make 5,000 additions and 300 multiplications per second.

    The second generation of computers starts, which used transistors to process information instead of vacuum tubes. New programming languages such as COBOL and FORTRAN were developed.
  • Integrated circuits

    Integrated circuits
    Integrated circuits begin to be used in the computers, which increased the processing capacity and reduced the size of the machines.
  • Microprocessor

    The microprocessor appears: a single integrated circuit in which the basic elements of the computer meet. The first personal computers begin to develop.
  • Apple

    Steve Jobs and Steve Wozniak make the Apple I. This computer allowed users to see what they were doing on a screen, unlike other models. Then an improved version called Apple II came, which sold millions of units.
  • IBM PC

    IBM PC
    The IBM PC is on sale as a home computer and revolutionizes computing. It increases the development of software and operating systems with which computers run.
  • WWW or WEB

    WWW or WEB
    It appears the WWW or Web, one of the main internet services, which makes the use of computers more useful in different areas.
