1. To study about various generations of
computer from 1946 to present.
Generations of
Computer
PPT By: Vijaya Vardhan Raj
2. Generations of Computer
First Generation (1946 – 1959)
Second Generation (1959 – 1965)
Third Generation (1965 – 1971)
Fourth Generation (1971 – 1980)
Fifth Generation (1980 – present)
3. First Generation of Computer
(1946 – 1959)
Vaccum Tube Technology was used
Computation time was in milli seconds
Computers are large in size are required lot of
space for installation.
Magnetic Tap (dreams) were used for memory
4. First Generation of Computer
(1946 – 1959)
They locked in versality & speed.
They are not portable.
They are very expensive to operate.
5. Second Generation of Computer
(1959 – 1965)
Transistor Technology are used
They are smaller as compared to first generation
Computation time was a micro second
They still required air conditioning.
6. Second Generation of Computer
(1959 – 1965)
They were more portable and produced less
amount of heat.
7. Third Generation of Computer
(1965 – 1971)
Integration Circuit Technology are used
They are smaller as compared two previous
generations
Computation time was in nano second
They were smaller in size and easily portable.
8. Third Generation of Computer
(1965 – 1971)
They were more reliable than previous
generations
9. Fourth Generation of Computer
(1971 – 1980)
Microprocessor Technology was used
They are very small in size.
They are portable and more reliable.
They can cheaper since production cost is low.
10. Fourth Generation of Computer
(1971 – 1980)
They generate less amount of heat.
They do not required air conditioning.
Only cooling fans are sufficient.
11. Fifth Generation of Computer
(1980 onwards & present)
Fifth Generation of computing device are based on
AI (Artificial Intelligence).
These are still in development.
They used various applications like voice
recognition, etc.
12. Fifth Generation of Computer
(1980 onwards & present)
Fifth Generation of computing device are based on
AI (Artificial Intelligence).
These are still in development.
There are some applications such as voice
recognition that are used today.
