Evolution of the computers

  • Eniac- The first computer

    Eniac- The first computer
    In 1946, John Mauchly and John Presper Eckert developed the ENIAC I (Electrical Numerical Integrator And Calculator).
  • UNIVAC 1- Business computer

    UNIVAC 1- Business computer
    Unlike the ENIAC, the UNIVAC processed each digit serially. But its much higher design speed permitted it to add two ten-digit numbers at a rate of almost 100,000 additions per second. Internally, the UNIVAC operated at a clock frequency of 2.25 MHz, which was no mean feat for vacuum tube circuits.
  • Transistorized computer

    Transistorized computer
    Tom Watson, Jr., led IBM to introduce the model 604 computer, its first with transistors, that became the basis of the model 608 of 1957, the first solid-state computer for the commercial market. Transistors were expensive at first, cost $8 vs. $.75 for a vacuum tube. —Steven E. Schoenherr
  • TRADIC—a fully transistorized computer

    TRADIC—a fully transistorized computer
    It was built by Bell Labs for the U.S. Air Force, which was interested in the lightweight nature of such a computer for airborne use. The machine consisted of 700 point-contact transistors and 10,000 germanium diodes. During two years of continuous operation only 17 of these devices failed, a vastly lower failure rate than Vacuum tube machines of the time.
  • Integrated circuit

    Integrated circuit
    It was a relatively simple device that Jack Kilby showed to a handful of co-workers gathered in TI's semiconductor lab more than 40 years ago -- only a transistor and other components on a slice of germanium. Little did this group of onlookers know, but Kilby's invention, 7/16-by-1/16-inches in size and called an integrated circuit, was about to revolutionize the electronics industry. —Texas Instruments
  • Modem

    Modem
    The first development efforts on digital modems appear to have stemmed from the need to transmit data for North American air defense during the 1950s.
  • IBM

    IBM
    IBM ships the first 1401 Data Processing System using Solid-state devices including transistors and the new generation of IBM Hard Discs.
  • Mouses

    Mouses
    Computer Mouse Prototype invented by Douglas Engelbart and Bill English, It was more than 20 years later that the public first gained any idea of how it could and would be used when it appeared in the Apple Macintosh in 1984.
  • ARPANET

    ARPANET
    Creation of ARPANET, the predecessor of the Internet
  • Microsoft

    Microsoft
    The name "Micro-soft" (for microcomputer software) and Microsoft becomes a registered trademark
  • Apple

    Apple
    Apple Computer Company is formed by Steve Jobs and Steve Wozniak.
  • Intel and Xerox
