Title: Computer Technology History


1
Computer Technology History
  • The affects of technology
  • on our society.

2
After completing this lesson, you will know
  • The history of computers from the 1940s up to the
    present.
  • The future of computing.
  • The many ways in which computers are used in
    modern life.
  • How to make computers accessible to persons with
    disabilities.
  • How computers are used in business and education.

Atanasoff-Berry Computer 1939
  • In late 1939, John Atanasoff teamed up with
    Clifford Berry to build a prototype. They created
    the first computing machine to use electricity,
    vacuum tubes, binary numbers and capacitors. The
    capacitors were in a rotating drum that held the
    electrical charge for the memory. 

5
History of Computing
  • 1940s
  • First computers built for breaking enemy codes
    in WWII
  • ENIAC (Electronic Numerical Integrator And
    Computer) first all-electronic computer

6
MARK series - 1944
  • Howard Aiken and Grace Hopper designed the MARK
    series of computers at Harvard University. The
    MARK series of computers began with the Mark I in
    1944. Imagine a giant roomful of noisy, clicking
    metal parts, 55 feet long and 8 feet high. The
    5-ton device contained almost 760,000 separate
    pieces. Used by the US Navy for gunnery and
    ballistic calculations, the Mark I was in
    operation until 1959.

7
Vacuum Tube
  • The vacuum tube was used to amplify voice and
    music. However, the tubes consumed power,
    created heat, burned out quickly, and required
    high maintenance.

Debugging
  • In the 1940s, computers were housed in buildings
    with no air conditioning. In the evening the
    researchers would leave the windows open to cool
    down the building and computers.

10
Debugging
  • The moths were attacked to the heat and lights
    and would get into the computers. It was common
    practice to get the bugs out of the computers
    every evening. This is how the phrase
    debugging came into being in the computer
    world.

11
History of Computing
  • 1950s
  • Invention of the transistor, resistor and the
    Integrated Circuit
  • IBM 650 7000 series

12
Worlds Most Powerful Computer in 1954
  • Faith Lillibridge at the NORC console fifth
    floor, Columbia University Watson Lab, 612 West
    115th Street NYC,

13
Transistors
  • The transistors were the first device designed to
    act both as a
  • Transmitter converting sound waves to electronic
    waves
  • Resistor controlling electric current

14
Integrated Circuit 1958 1959
  • Integrated Circuit or Silicon Chip was invented
    by two separate inventors.
  • A single chip could contain the electronic
    circuitry of the entire computer.

15
1950s Key milestones in 1953
  • First released in 1953 with magnetic drum memory
    and priced at less than half a million dollars,
    the 650 was relatively cheap.

16
History of Computing
  • 1960s
  • DECs PDP-1
  • The IBM 1130
  • Hewlett-Packard entered the general purpose
    computer business

18
DECs PDP-1
  • The precursor to the minicomputer, DECs PDP-1
    sold 50 for 120,000. Its large scope intrigued
    early hackers at MIT, who wrote the first
    computerized video game, SpaceWar!
  • First mini-computers from DEC and IBM

19
The IBM 1130 (1965)
  • The first IBM computer to rent for less than
    1000 a month." Intended for use by scientists,
    engineers, and mathematicians.

20
History of Computing
  • 1970s
  • Xerox Alto first Graphical User Interface
  • (GUI) computer (1975)
  • MITS Altair first personal computer (1975)
  • Tandy/Radio Shack personal computer (1975)
  • Wozniak and Jobs design Apple I and II
  • 1977 was the first hacker break in into a
    Columbia computer from the outside, and it went
    to court
  • 1977-1978 First use of email at universities on a
    bulletin board system.

21
Xerox Palo - the first work station with a
built-in mouse 1973
  • Researchers at the Xerox Palo Alto Research
    Center designed the Alto the first work station
    with a built-in mouse for input. The Alto stored
    several files simultaneously in windows, offered
    menus and icons, and could link to a local area
    network. Although Xerox never sold the Alto
    commercially, it gave a number of them to
    universities. Engineers later incorporated its
    features into work stations and personal
    computers.

22
Commodore PET
  • The Commodore PET (Personal Electronic Transactor
    or maybe rumored to be named after the "pet rock"
    fad) was designed by Chuck Peddle. It was first
    presented at the January, 1977, Winter Consumer
    Electronics Show and later at the West

23
History of Computing
  • 1980s
  • IBM (1981) and DOS
  • MAC (1984)
  • Portable computers debut

IBM - 1980
  • In July of 1980, IBM representatives met for the
    first time with Microsoft's Bill Gates to talk
    about writing an operating for IBM's new
    hush-hush "personal" computer

26
1984 Macintosh 128k
  • Released with much fanfare in January of 1984,
    the Macintosh was the first affordable computer
    to include a Graphical User Interface.

27
History of Computing
  • 1990s
  • Personal computers improve dramatically
  • Microsoft Windows 3.0 (1990)
  • Internet and World Wide Web

28
History of Computing
  • 2000s
  • High-speed Internet access
  • Instant messaging
  • Tablet PC
  • E-commerce
  • Security viruses, worms, hacks, identity theft

29
Computers of today are not only more compact, but
efficient.
30
Computer Accessories
  • Printers today can print, copy, scan and fax, as
    well as print directly from your digital camera.

31
Accessible Technology
  • Accessibility features
  • An operating system and software with features
    that can be adjusted and customized to your own
    accessibility needs.
  • Assistive technology products
  • Designed to accommodate an individuals
    disability or multiple disabilities.
  • Compatibility
  • An operating system and software compatible with
    a specific type of assistive technology product.
