Computer Science
and Society

Before 1920s
human clerks that performed computations
1880, US Census
Population grown so large that it took years to tabulate it.
30.2% increase
Census Bureau contracted
Herman Hollerith
He build a tabulating machine that performed that task in years
Social Networking?
World War II
1941 Bombe
To decrypt Nazi military communications.
Many Bombe were built.
Together they dramatically improved the intelligence and processing capabilities of Allied forces.
Project Whirlwind
U.S. Navy approached MIT to build a flight simulator to train bomber crews.
Built in 1951, US Navy no more interested.
Bell Labs Contribution
1943: A machine for assisting anti-aircraft guns was completed by Bell Labs, for U.S. Army.

1944: Ballistic Computer for calculating ballistic trajectories.

1945: Second Ballistic Computer
1944 Colossus
Designed by Britishers to break
the complex Lorenz ciphers used
by Nazis.
Personal Computing
Modern Era
Long distance communication
World Trade and Commerce
Personal Entertainment
Software Industry
Computers enter the world of trade and commerce.
Companies were using computers to increase efficiency, e.g. management, process scheduling, employees could use computers to do necessary calculations, documentation, etc.
As time passes, advancement in computers make it possible for people to have one at home.
