A computer is an electronic machine that accepts information
(Data), processes it according to specific instructions, and
provides the results as new information.

4. Charles Babbage (1791-1871)
The Father of Computers
Charles Babbage is recognized today as the Father of
Computers because his impressive designs for the
Difference Engine and Analytical Engine
foreshadowed the invention of the modern electronic
digital computer

5. Charles Babbage
 English inventor
 1791-1871
 Taught math at
Cambridge University
 Invented a viable
mechanical computer
equivalent to modern
digital computers

6. Babbage’s first computer
built in early 1800’s
special purpose calculator
naval navigation charts

7. The first computer bug
Rear Admiral Dr Grace
Murray Hopper

8. Babbage’s second computer
 Analytical engine
 general-purpose
 used binary system
 punched cards as input
 branch on result of
previous instruction
 Ada Lovelace (first
programmer)
 machined parts not
accurate enough
 never quite completed

9. 2nd Generation 1955-1963
 Transistors
 Memory - magnetic core
 Assembly language
 Printers and memory
 Programming languages
 Careers

10. 1962 – First computer game
& word processor
 Steve Russell at MIT invents
Spacewar, the first
computer game running on
a DEC PDP-1.
 Because the PDP-1 had a
typewriter interface, editors
likeTECO (Text Editor and
Corrector) were written for
it.
 Steve Piner and L. Peter
Deutsch produced the first
“word processor” called
ExpensiveTypewriter (MIT's
PDP-1 cost $100,000).

12. 3rd Generation 1964 - 1971
 Quartz clock
 Integrated circuit
 Operating systems

14. 4th Generation 1971 - now
 LSI - Large Scale Integration
 VLSI- Very Large Scale Integration (ULSI)
 Chip
 General consumer usage
 Networks

16. 1975 - 1981

17. 5th Generation
 This is the future
 What will it be like?
 What changes will be big enough to create
this new generation?

21. Two Inventions that changed
the way computers are built!!
961
The IC revolutionized the
entire electronic technology.
Ex: The Pentium Processor
contains 3.1 Million Transistors
in 1.5 inch square!
