Title: History of the Computer
1History of the Computer
2The Abacus
- The first abacus was invented around 2600 B.C.
- It is a hand-held wooden device with rows of
beads, to add, subtract, divide and multiply
3Digital Calculator
- In 1642, Blaise Pascal, a French
- Mathematician and philosopher,
- invents the first mechanical digital
- calculator using gears, called the
- Pascaline.
4The Analytical Engine
- In 1833, Charles Babbage, a computer pioneer,
designed the first automatic computing engines
5Tabulating Machine
- Dr. Herman Hollerith introduced the first
electromechanical, punched-card data-processing
machine which was used to compile information for
the 1890 U.S. census.
In 1924, Hollerith founded International Business
Machines (IBM).
6Electronic Digital Computer
- In 1939, Dr. John V. Atanasoff and his assistant
Clifford Berry build the first electronic digital
computer. Their machine, the Atanasoff-Berry-Compu
ter (ABC) provided the foundation for the
advances in electronic digital computers
7Programmable Computer
- 1941 - Konrad Zuse introduced the first
programmable, fully automatic computer. It was
designed to solve complex engineering equations.
This machine was called the Z3
8Automatic Computing Engine (ACE)
- In 1945, Alan Turing joined the National Physical
Library in London to design an early electronic
stored-program computer - His report was the first relatively complete
specification of an electronic stored-program
general-purpose digital computer - very detailed - His proposal supplied detailed circuit designs
and specification of hardware units, specimen
programs in machine code, and even an estimate of
the cost of building the machine - His design called for a high-speed memory of
roughly the same capacity as an early Macintosh
computer (enormous by the standards of his day)
9UNIVAC 1
In 1951, the UNIVAC 1 (Universal Automatic
Computer) was designed by J. Presper Eckert and
John Mauchly The first UNIVAC came on line for
the U.S. Government's Census Bureau. The first
commercial customer to purchase a UNIVAC was the
Prudential Insurance Company.
8 UNIVACs were installed and in

10The Chip
- In 1959, Jack St. Clair Kilby and Robert Noyce of
Texas Instruments manufactured the first
integrated circuit, or chip (microchip) and were
the founders of INTEL - The microchip enabled the development of personal
computers, mobile phones and many other electric
household goods,
11- The invention of the chip led to the development
of even smaller chips that produced faster and
better results - Up to this point computers were large - mainframe
computers, including IBMs System 360 designed by
Gene Amdahl in 1960
12The Minicomputer
- In 1963, Ken Olsen introduces the first
minicomputer developed by the Digital Equipment
Corporation, founded by Olsen - This was a huge developmental breakthrough in the
world of technology
13The Internet
- The internet was brought online in 1969
14The Altair
- "Ed" Roberts American engineer, entrepreneur and
medical doctor designed the first commercially
successful personal computer in 1975. - The new computer used the new Intel 8080
microprocessor.
15Osborne I
- In 1981, Adam Osborne completed the first
portable computer, the Osborne I, which weighed
24 pounds and cost 1,795. The price made the
machine especially attractive, as it included
software worth about 1,500. The machine featured
a 5-inch display, 64 kilobytes of memory, a
modem, and two 5 1/4-inch floppy disk drives
16Commodore 64
- In 1982, Commodore introduces the Commodore 64.
The C64, as it was better known, sold for 595,
came with 64KB of RAM and featured impressive
graphics. Thousands of software titles were
released over the lifespan of the C64. By the
time the C64 was discontinued in 1993, it had
sold more than 22 million units and is recognized
by the 2006 Guinness Book of World Records as the
greatest selling single computer model of all
time.
17Apple Computer
- Steve Jobs and Stephen Wozniak began Apple
Computer in 1976 - A year later, the Apple II was created and
included color graphics and which housed its
electronics inside a plastic case. Programmers
began creating applications for the Apple II at
Jobs' urging soon there were more than 15,000
applications available for the machine. This, the
first mass marketed personal computer, took Apple
to a new realm of success.
18Macintosh
- Apple Computer launched the Macintosh, the first
successful mouse-driven computer with a graphic
user interface, with a single 1.5 million
commercial during the 1984 Super Bowl. Based on
the Motorola 68000 microprocessor, the Macintosh
included many of the Lisas features at a much
more affordable price 2,500.
19Microsoft
- In 1975, Bill Gates and Paul Allen create
Microsoft - In 1980, Gates discovered MS-DOS a computer
software that would run on any PC computer -
- By 1983, Microsoft was going global with offices
in Great Britain and Japan, and with 30 percent
of the world's computers running on its software.
- In November 1985, Bill Gates and Microsoft
launched Windows
- Bill Gates stepped down from the day-to-day
operations of Microsoft in 2000, turning over the
job of CEO to college friend Steve Ballmer who
had been with Microsoft since 1980. He still
remains chairman of the board. - His last full day at Microsoft was June 27, 2008
20World Wide Web
- In 1990, the World Wide Web was born when Tim
Berners-Lee, developed HyperText Markup Language.
HTML, as it is commonly known, allowed the
Internet to expand into the World Wide Web, using
specifications he developed such as URL (Uniform
Resource Locator) and HTTP (HyperText Transfer
Protocol). A browser, such as Netscape or
Microsoft Internet Explorer, follows links and
sends a query to a server, allowing a user to
view a site.
