History of Computer

Did you know...

• The first idea for a computer was in the early 1800s• Charles Babbage is the man who is credited with this idea.

Important Parts of Computer History

• Early Computational Devices• Early Computers• Generations & Main Component• Inventors/Developers• Internet

Early Computational Devices

• Abacus• Punched Cards

Abacus

• Early aid for mathematical computations.

• Measures the speed of a computer

Punched Cards

• Early form of input devices.• Enabled computers to do tasks.

Early Computers

• ENIAC• Mark1• EDSAC• EDVAC• UNIVAC

ENIAC

• (Electronic Numerical Integrator And Computer)

• The first general use computer.

Mark1

• Electro-mechanical computer• Used for storage

EDSAC

• (Electronic Delay Storage Automatic Calculator)

• Second practical stored-program electronic computer.

EDVAC

• (Electronic Discrete Variable Automatic Computer)

• One of the earliest computers.

UNIVAC

• (Universal Automatic Computer)• First commercial computer produced

in US.

Generations of Computers

• First Generation• Second Generation• Third Generation• Fourth Generation• Fifth Generation• Generation Worksheet

First Generation

• Vacuum tubes were used for circuitry.

• Magnetic drums were used for memory.

• The size of the early computers took up an entire room

Second Generation

• Transistors replaced vacuum tubes.• Were now smaller, faster, and more

efficient.

Third Generation

• Semiconductors replaced transistors.• Computers now increased in speed

and efficiency.• Devices could run multiple apps at a time.

Fourth Generation

• Currently used• Integrated circuits were equipped

within a single chip.• Instead of an entire room, it can now fit in someone’s hand.

Fifth Generation

• Still in development• Will use parallel processing and

superconductors to create artificial intelligence.

• These new devices will be capable of learning.

Inventors/Developers

• Steven Jobs & Steven Wozniak• Bill Gates & Paul Allen• Charles Babbage• Herman Hollerith• Blaise Pascal• John Von Neumann• Presper Eckerty & John Mauchly

Steven Jobs & Steven Wozniak

• Creators of Apple Inc.• Released first Apple computer (Apple

I) on April 1, 1976

Bill Gates & Paul Allen

• Creators of Microsoft/Windows.• First Microsoft computer (Windows

1.0) is announced November 20, 1985.

Charles Babbage

• Father of Computing• Originated the concept of a

programmable computer.

Herman Hollerith

• The founder of IBM• Created and used punched cards.

Blaise Pascal

• Famous mathematician & physician• Created a machine that

automatically adds and subtracts.

John Von Neumann

• Famous American mathematician that contributed to the development of computers.

• Developed a software written in binary code.

Presper Eckert & John Mauchly

• Created the first all electronic computer, the ENIAC

• Formed EMCC to build new computer designs for commercial and military applications.

Internet

• Birth of the Net• Mosaic Browser• Worldwide Web• ARPANET

Birth of the Net

• Invented in 1969• Created a computer network that

would continue to function in the event

of a disaster.

Mosaic Browser

• World’s first web browser• Created by Marc Andreesen

=

Worldwide Web

• World’s first communicating system• Created by Tim Berners-Lee

=

ARPANET

• Later changed to the Internet• Created by the Department of

Defense.

All in All

• Without these people and the developments they contributed, we would not be any where near close

to the computers we have now.
