Charles Babbage is considered the father of computers, as he invented the first mechanical computer called the Difference Engine in the early 1800s. The computer was a special purpose calculator used for navigation. Computers have since evolved through 5 generations from vacuum tubes to transistors to integrated circuits to microprocessors and now artificial intelligence. Early computers were mainly used for calculations, but later designs incorporated programs allowing computers to perform ordered tasks. IBM was a major computer manufacturer starting in the 1980s, producing notable computers through significant programming efforts for calculations and other purposes.

4. THE GENERATIONS OF A COMPUTER
There are 5 generations of a
computer :
 First Generation (1940-1956) Vacuum Tubes
 Second Generation (1956-1963) Transistors
 Third Generation (1964-1971) Integrated Circuits
 Fourth Generation (1971-Present year)
Microprocessors
 Fifth Generation (Present and Beyond) Artificial
Intelligence

6. HISTORY OF COMPUTERS
Generally in those days computers
are used for mainly calculations.
Later on they started to make new
designs and programs that the
computer do which we order.
A microcomputer is a complete
computer which is small in size.

7. IBM COMPUTERS
IBM was one of the largest
companies which made computers.
The computers which IBM made were
the most notable computers.
They started in 1981.
They programmed it with a lot of effort
and used it for calculation and other
purposes.
