Computer Generations

The five generations of computers

Even more so the generation who have grown from infancy within the global desktop and laptop revolution since the 1980s.

The history of the computer goes back several decades however and there are five
definable generations of computers.

 Each generation is defined by a significant      technological development that changes    fundamentally how computers operate –  leading to more compact, less expensive, but  more powerful, efficient and robust machines.

1. First Generation
2. Second Generation
3. Third Generation
4. Fourth Generation
5. Fifth Generation

Following are the main five generations of computers 

S.N.	Generation & Description
1	First Generation The period of first generation: 1946-1959. Vacuum tube based.
2	Second Generation The period of second generation: 1959-1965. Transistor based.
3	Third Generation The period of third generation: 1965-1971. Integrated Circuit based.
4	Fourth Generation The period of fourth generation: 1971-1980. VLSI microprocessor based.
5	Fifth Generation The period of fifth generation: 1980-onwards. ULSI microprocessor based
