33. What Is A Computer?

34. History of Computing
•Early computing devices
Abacus: positions of beads represent
numbers
Gear-based machines (1600s-1800s)
•Positions of gears represent numbers
•Blaise Pascal, Wilhelm Leibniz, Charles Babbage

35. Chinese Wooden Abacus
35/54

36. Early Data Storage
•Punched cards
First used in Jacquard Loom (1801) to store
patterns for weaving cloth
Storage of programs in Babbage’s Analytical
Engine
Popular through the 1970’s
•Gear positions

37. Early Computers
•Based on mechanical relays
1940: Stibitz at Bell Laboratories
1944: Mark I: Howard Aiken and IBM at Harvard
•Based on vacuum tubes
1937-1941: Atanasoff-Berry at Iowa State
1940s: Colossus: secret German code-breaker
1940s: ENIAC: Mauchly & Eckert at U. of Penn.

38. The ENIAC computer
38/54

39. History Note
•First programmable computer
Designed by Charles Babbage
Began work in 1822
Not completed in Babbage’s life time

•First programmer
Ada Augusta, Countess of Lovelace
•Colleague of Babbage
•Created the first algorithm intended to be carried
out by Babbage’s machine.
•The first to recognize the full potential of a
"computing machine“.

40. •Bit: Binary Digit (0 or 1)
•Bit Patterns are used to represent information
Numbers
Text characters
Images
Sound
And others
