The Evolution and Future of Computer Technology

  • Invention of the loom

    Invention of the loom
    In France, Joseph Marie Jacquard invents a loom that uses punched wooden cards to automatically weave fabric designs. Early computers would use similar punch cards.
  • Failed invention of the computer

    Failed invention of the computer
    English mathematician Charles Babbage conceives of a steam-driven calculating machine that would be able to compute tables of numbers. The project, funded by the English government, is a failure. More than a century later, however, the world’s first computer was actually built.
  • Calculator

    Calculator
    Herman Hollerith designs a punch card system to calculate the 1880 census, accomplishing the task in just three years and saving the government $5 million. He establishes a company that would ultimately become IBM
  • invention of the Turning machine

    invention of the Turning machine
    Alan Turing presents the notion of a universal machine, later called the Turing machine, capable of computing anything that is computable. The central concept of the modern computer was based on his ideas.
  • Computer without gears, cams, belt or shafts

    Computer without gears, cams, belt or shafts
    J.V. Atanasoff, a professor of physics and mathematics at Iowa State University, attempts to build the first computer without gears, cams, belts or shafts.
  • First time computer is able to store information

    First time computer is able to store information
    Atanasoff and his graduate student, Clifford Berry, design a computer that can solve 29 equations simultaneously. This marks the first time a computer is able to store information on its main memory.
  • grandfather of digital computers

    grandfather of digital computers
    Two University of Pennsylvania professors, John Mauchly and J. Presper Eckert, build the Electronic Numerical Integrator and Calculator (ENIAC). Considered the grandfather of digital computers, it fills a 20-foot by 40-foot room and has 18,000 vacuum tubes.
  • first commercial computer for business and government applications

    first commercial computer for business and government applications
    Mauchly and Presper leave the University of Pennsylvania and receive funding from the Census Bureau to build the UNIVAC, the first commercial computer for business and government applications.
  • invention of the transistor

    invention of the transistor
    William Shockley, John Bardeen and Walter Brattain of Bell Laboratories invent the transistor. They discovered how to make an electric switch with solid materials and no need for a vacuum.
  • The invention of the UNIX

    The invention of the UNIX
    A group of developers at Bell Labs produce UNIX, an operating system that addressed compatibility issues. Written in the C programming language, UNIX was portable across multiple platforms and became the operating system of choice among mainframes at large companies and government entities. Due to the slow nature of the system, it never quite gained traction among home PC users.
  • First DRAM

    First DRAM
    The newly formed Intel unveils the Intel 1103, the first Dynamic Access Memory (DRAM) chip.
  • invention of the floppy disks

    invention of the floppy disks
    Alan Shugart leads a team of IBM engineers who invent the “floppy disk,” allowing data to be shared among computers.
  • First Ethernet cable

    First Ethernet cable
    Robert Metcalfe, a member of the research staff for Xerox, develops Ethernet for connecting multiple computers and other hardware.
  • New computers

    New computers
    A number of personal computers hit the market, including A number of personal computers hit the market, including Scelbi & Mark-8 Altair, IBM 5100, RadioShack’s TRS-80 —affectionately known as the “Trash 80” — and the Commodore PET.
  • Getting known

    Getting known
    Radio Shack's initial production run of the TRS-80 was just 3,000. It sold like crazy. For the first time, non-geeks could write programs and make a computer do what they wished.
