- Be sure to see the quiz review page.
Outline/important points of the video:
- Eckert, Mauchly, ENIAC. $3,000,000 cost.
- ``Only a few dozen computers will ever be needed and only by
scientists.'' Why is this ironic?
- Eckert and Mauchly see a market for computers in business.
- Criticisms of computers: too expensive, too unreliable, too difficult
- First customer: Census Bureau. Why did they want a computer?
- First commerical computer: UNIVAC.
- First large scale public exposure to a computer: the 1952
- Solving the programming crisis: high level programming languages.
FORTRAN for scientific, COBOL for business.
- Fear: automation --- loss of jobs. ``Good tools'' replace ``bad
jobs''? Creation of less tedious jobs.
- Transistor: major improvement over the vacuum tube. Transistor was
much smaller, generated little heat, consumed little power. Shockley.
- Wiring: the tyranny of numbers. Solution: the integrated circuit.
Kilby and Noyce.
- ICs were too expensive. Solution: great need by NASA (space program)
and the military (missles, jets) drove prices down (mass production).
- Silicon valley: the heart of the computing industry.
