Programs written in simple codes, then
converted to punch tapes and fed into the machine was originally used by Camp
Bridge Machine to speed the actions of scientific calculations.
3. In

II.
4. What
is the contribution of Allan Turing during the World War II?
Alan Turing, British Mathematician who is
involved in cracking German’s code during the World War II, designed the Pilot
Ace in 1946 and Lorenz, a machine that scrambled letter in a pattern way for
communication purposes.
5. What
is the name of the first commercial computer in US?
UNIVAC is made of vacuum tubes but too complex
as people are required to understand and master Advanced Math and logic just to
operate the machine.
6. Which
company finally made the first commercial computer in US?
Eckert-Mauchly sold the machine to US
Census Bureau to process population data, record keeping and accounting
purposes for $350,270 in September 1946.
7. When
did IBM enter the computer business and who was the main driver?
International Business Machine was
originally keen on keep using the punch cards on tabulating data until 1951 when
US Census Bureau, one of their customers, ordered UNIVAC machines. That’s why
Thomas Watson Jr. decided to change IBM from inside out as the market clearly
changed and enter the computer business and designed scientific computer rather
than a commercial computer.
8. In

Lyons decided to build their own computer with the help from a student in

9. What
are the social effects of using computers in factory and office automation?
UNIVAC was used to forecast the outcome of
election in 1952 which simplified a lot of things.
10. When
did Apple design the first personal computer?
11. When
the mouse was designed?
12. What
is ALTAIR 8800 and when did it appear in the market?
13. What
is the contribution of Xerox in the evolution of computer?
14. When

was the major problem in the first generation personal computers?
16. What
are the main features of Macintosh as compared with other personal computers in
1984?
17. What
are the technological advancements, both in hardware and software, from the
first generation electronic computers to the era of personal computers?
18. What
is program?
19. How
disable persons can be benefited from the computer technologies?
