2. what is Computer ?
• The word computer comes from the word “compute” which means to
calculate.
• People usually consider computer as
calculating device that can perform calculation
accurately at a very high speed.
• But this trend is on more been today's modern
era computer as it provide multiple function other
then calculation.
• Computer are used for data processing & problem solving related to
scientific as well as research activities.

3. Charles Babbage
Father OF Computer
• A British Mathematics professor.
• He was born in England in 1792 as the son
of a rich banker from Devon.
• He was inspired by Napier's logarithm
tables.
• He began to design a "difference engine"
in 1821 which was a very large and
complicated machine intended for doing
logarithmic calculations automatically

5. There are 5
Generations of
computers:-
1. First Generation(1946-1955)
2. Second Generation(1956-1965)
3. Third Generation(1966-1975)
4. Fourth Generation(1976-1985)
