History of Computing

  • Machanical calculator

    It implements algorithems autonomusly. It upgraded he manual calculators of the past.

  • Difference Engine

    It operated using steam power. It was intended to accurately and quickly calculate large tables of numbers used for astronomical and enginerring applications.

  • Analythical Engine

    It was never completed, but naby computer historians believed that it had many aspects of what many modern computers have today, like memory, a programable processor and an output device amoung others.

  • The Hollerith Tabulating Machine

    It worked as a card reader during 1896 and 1924 and was part of the company name created by Herman Hollerith. The name was eventually changed to IBM as it is known today.

  • First-generation computers

    These computers used vacuume tubes as their source of energy, but they came with some problems as well. This generation wasn't too well known or used in the time it was created so many companies attempted to make it better and bring it up to speed.

  • Vacuume Tube

    Vacuume Tube
    They were used power the electronic computers, but used up a large amount of energy and burned out fairly quickly. Site:

  • Computer prototypes

    There are many computer prototypes ranging from 1937 to 1942. One of these prototypes was called Atanasoff-Berry Computer or ABC for short. It was the first to use the vacuum tubes and is considered the first electronic digital computer.

  • Harvard Mark 1

    IBM sponsored the creator of this machine who combined 73 IBM Automatic Accounting Machines into one unified unit. It was originally named the IBM Automatic Sequence Calculator or ASCC for short. It has now been named the Harvard Mark 1 since it was moved to Harvard University after its completion.

  • The Z3

    The Z3
    Created by Konrad Zuse, it was enshrouded in secrecy and didn't surface until after the war ended. It had little effect on the development of computers due to the fact that it was hidden for so long. Site:

  • Second Generation of computers

    These computers used transistors instead of vacuum tubes and eventually replaced them by the late 1950's.

  • Transistors

    Transistors
    These devices replaced vacuum tubes after a certain amount of time because they were more reliable and used less energy than the tubes did.

  • UNIVAC

    It was cunstructed under the auspices of the Eckert-Mauchly Computer Corp. Due to finacial issues, one of IBM's chief rivals, Remington Corp. took over and sold about 46 to their customers between 1951 and 1958.

  • The third Generation of Computers

    This generation became possible during 1958. It started with the creation of a chip that was able to store energy much more efficiently than either transistors or vacuum tubes.

  • RCA Spectra 70

    This was a computer that was one of the first to incorporate integrated curcits.

  • IBM 360

    This was another more succeful computer that had incorporated integrated curcits.

  • DEC PDP-8

    DEC PDP-8
    It was the first successful minicomputer. Site:

  • Mark-8

    Created by Jonathan A. Titus who was featured in the July 1974 issue of Radio Electronics.

  • Fourth Generation of Computers

    Started when Ted Hoff created the first Microprocessor.

  • Intel 4004

    Intel 4004
    It was the first microprosessor and it was created by Ted Hoff. It started a generation of smaller, faster and cheeper computers something that the third generation couldn't accomplish. Site:

  • 6502 8-bit processor

    Created a few mouths after the creation of the 6800. It was primarilly used in Apple II and Commodore personal computer systems.

  • Z80 micorprocessor

    Created by Zilog. It was an enhanced 8080 microprocessor and it was used in many early computer systems. It was quickly challenged by Intel in the same year.

  • Intel 8085 microprocessor

    Created by Intel as a competitor and an enhancement on Zilog's version.

  • Apple 1

    Steve Jobs and Steve Wozinak founded Apple Computer Corporation and released it.

  • IBM AS/400

    It was renamed the iSeries 400. It was one of hte few remaining devices that could be classified as a minicomputer.

  • Moterolla 6800 8-bit processor

    Created by Moterolla and a competitor was created by ex-Moterolla employees called the 6502 8-bit processor.
