What is computer :- Computer is an electric device that is designed to work with information. The term computer is derived from the Latin term “computer”, this means to calculate or programmable machine. Computer can not do anything without a programme. Charles Baffage is called the “grand father” of the computer. The first mechanical computer designed by Charles Baffage was called Analytical Engine. It uses read-only memory in the form of punch card.
Computer is an advanced electronic device that take raw data as input from the uses and processes these data under the control of set instructions (output) and save output for future use. It can process both numerical and non-numerical (arithmetic and logical) calculations.
Generations :-
First Generation :-
The period of first generation: 1946-1959 vacuum tube based.
Second Generation :-
The period of second generation : 1959-1965. Transistor based.
Third Generation :-
The period of third generation :1965-1971. Integrated Circuit based.
Forth Generation :-
The period of fourth generation: 1971-1980.VLSI microprocessor based.
Fifth Generation :-
The period of fifth generation: 1980 on words ULSI microprocessor based.
