History of Computing

Timeline created by mpa5058
  • First Generation Computers

    The day and month may not be right. Computers began to come about.
  • Vacuum tubes

    Vacuum tubes
    Was used on all the First Generation computeers.

  • Atanasoff-Berry Computer (ABC)

    Atanasoff-Berry Computer (ABC)
    Was the first to use vaccum tubes instead of mechanical switches for processing circitry. Considered the first electronic digital computer.

  • Z3

    Was designed to work with binary numbers. Built by Nazi Germany during WWII.

    Electronic device designed to decode messages encrypted be the German Enigma machine. Contained 1,800 vacuum tubes.

    Electronic Numerical Intergrator and Computer, was designed to calculate trajectory tables for the U.S. Army. It could perform 5,000 additions per second.

    Again the date might not be right, but is considered the first commercially successful digital computer. The first UNIVAC computer was constructed under the auspices of the Eckert-Mauchly Computer Corp.
  • Second Generation

    Not sure the date again, does not say in the book. They used transistors instead of vacuum tubes.
  • Transistors

    Regulate current or voltage flow and acts as a switch for electronic signals.

  • Companies

    IBM, Burroughs, Control Data, Honeywell, and Sperry Rand all manufactured computers with transistors.
  • IBM's Business computer

    Operating systems that provided stamdardized routines for input, output, memory management, storage, and other resource managment activities.
  • Third Generation Computers

    Used intergrated circutry
  • RCA Spectra 70

    One of the first two computers to incorperate intergrated circuits.
  • IBM 360

    IBM 360
    The second of the first two to recieve intergrated circuits.

  • DEC PDP-8

    The first successful minicomputer. They were built to be smaller and less powerful then the mainframe, but still be able to run multiple programs at once.
  • Fourth Generation Computers

    Ted Hoff developed the first general-purpose microprocessor.
  • 8-bit Microprocessor

    Motorola released the first 8 bit microprocessor.
  • Mark-8

    Was a personal computer developed by Jonathan A. Titus.

  • MITS Altair

    Was the first commercial microcomputer. Based on the Intel 8080 processor.
  • Z80 microprocessor

    Was an enhanced 8080 microprocessor that was used in many early computer systems.
  • Apple I

    A kit containing a system board with 4 KB of RAM.
  • Apple II

    Featured color graphics, expansion slots, a disk drive, a 1.07 MHz 6502 processor, and 16 KB of RAM.
  • IBM PC

    IBM PC
    Had 4.77 MHz Intell 8088 processor, 16KB of RAM, and single sided 160 KB floppy disks drives.

    Featured with RAM upgradable to 640 KB, and a 10 MB hard disk drive.
  • Apple Lisa

    the key feature was the graphical user interface.
  • Apple MAcintosh

    Apple MAcintosh
    Featured a graphical user interface that made programs easier to use than those on the commandd-line-base IBM PC.
