history of the computers

  • first computer

    first computer
    The first computers used vacuum tubes for circuitry, magnetic drums and magnetic cores for memory, and were often enormous, taking up entire rooms.
  • second computer invented

    second computer invented
    The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors.
  • third computer invented

    third computer invented
    The third generation is characterized by the development of the integrated circuit - a complete electrical circuit whose components are fabricated onto a small "chip" made of silicon otherwise known as an integrated circuit chip IC chips drastically increased the speed and efficiency of computers
  • fourth computer invented

    fourth computer invented
    The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer—from the central processing unit and memory to input/output controls—on a single chip

    first laptop ivented
    The laptop was invented by Adam Osborne in 1981. It was called 'Osborne 1' and cost $1,795. It came bundled with $1,500 worth of programmes. It had a tiny computer screen built into it. It was invented by Osborne Computers. The first portable computer was a success, with sales reaching 10,000 units a month. IBM launched the IBM 5155 Portable Personal Computer in 1984. In 1988, Compaq Computer launched the first laptop PC with VGA graphics, Compaq SLT/286. In 1989, NEC released UltraLite, which

    fifth generation computer ivented
    Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language

    first ipad ivented
    the ipad is a line of tablet computers designed and marketed by Apple Inc., which runs Apple's iOS operating system. The first iPad was released on April 3, 2010; the most recent iPad models, the fourth-generation iPad and iPad Mini, were released on November 2, 2012. The user interface is built around the device's multi-touch screen, including a virtual keyboard. The iPad has built-in Wi-Fi and, on some models, cellular connectivity
