Computer History
Ancient Computers:
The most ancient computer was Abacus. It was first automatic computer which was used for the purpose of calculating and counting.
Blaise Pascal invented the Pascaline. this device could perform simple addition, subtraction multiplication division.
Modern Computers
Charles Babbage:
On 19th century (1837) English mathematician Charles Babbage created a machine for calculation purpose. He named it as a Analytical Engine.
Charles Babbage considered as "The father of computer/the father of modern day computing"
Computer Generations:
First Generation Computer
(1940-1956)
Vaccum tubes (valves) were used
Second Generation Computers:
(1956-1963)
Transistors were used
More speed as compared to first generation.
Third Generation computer
(1964-1971)
Integrated circuits(IC) were used
Speed increased as compared to previous generations.
It never became warm.
Fourth Generation computers:
(1971-1990)
Microprocessors are used in forth generation computers.
Due to the use of microprocessors forth generation computers became very small sized computers.
Fifth Generation computers:
(1990 and till)
ex: Computer having "Artificial Intelligence", Robots.
