1st GENERATION (1940-1956):
They used vacuum tubes and magnetic drums . They used a great deal of electricity and generated a lot of heat . They could solve only one problem at a time. ex- ENIAC AND UNIVAC
2nd GENERATION (1956-1963):
Transistors replaced vacuum tubes in the second generation of computers. Programming became easier with these computers . ex- IBM704
3rd GENERATION (1964-1971):
Integrated  circuits replaced transistors in this generation.Data storage was increased. ex-IBM360
4th GENERATION (1971- TILL NOW ):
These computers  use Microprocessors which is a small chip that has a number of integrated circuits in it. Many programs can be run on these computers at a time . ex- Personal Computer , WORKSTATIONS
5th GENERATION (FUTURISTIC):
These computers are still in development stage and are generally referred as SUPERCOMPUTERS.
