3. We will Discuss
Introduction
First Generation Computers
Second Generation Computers
Third Generation Computers
Fourth Generation Computers
Fifth Generation Computers
4. Definition of Computer
Computer is an advance electronic device
that manipulate information/data. It has the
ability to retrieve and process data.
It can perform Arithmetic and Logical
calculation.
8. It starts from 1942-1956.
They used Vacuum Tubes as for circuitry and
for memory.
They were very expensive.
They consumed alot of electricity.
They were bigger in size, as they occupied a room
space
UNIVAC and ENIAC computers are examples of first-
generation computing
1st Generation Computer
9.
10. Limitation Of 1stGeneration Computer
They were large in size.
They consumed large amount of electricity.
Operating of computers were costly.
It’s maintenance was costly.
It was not portable.
They generate a lot of heat.
12. 2ndGneration Of Computer
The 2nd Generation of computers
starts with the development of
transistor, It was continued from 1956-
64.
They were smaller, faster and cheaper
than 1st generation computers.
They consumed less electricity due to
use of transistor.
They generate less heat.
13. Limitation of 2nd Generation Computer
They were also required cooling system.
They were used for specific purpose.
They were also very large in size.
15. 3rd Generation Computer
The third Generations starts with
development of IC in 1964 and continued
till 1972.
They were faster than 1st and 2nd
generation computer.
They were smaller, cheaper and reliable
than 1st and 2nd generation computers.
They consumed less electricity.
16.
17. Limitation of 3rdGeneration Computer
Due to use of IC highly sophisticated
technology was required.
Still required Cooling system.
It was cheaper but not for home use.
19. 4th Generation Of Computer
This generation starts from1972 to
onward.
4th Generation of computer relied on
microprocessor which contains thousands
of circuits in it.
They are smaller, portable, reliable and
cheaper.
The storage capacity was very much
increased.
This generation computers were very user
user friendly.
20. The development of microprocessor
revolutionized electronic gadgetry.
Smart devices use micro-controllers
and are called dedicated computers.
24. 5th Generation Of Computer
The fifth generation computers
are still undergoing development.
They will have artificial
intelligence
They will be able to recognize
image, objects and weather
forecasting
25. They will be able to accept
instructions in voice messages,
normal conversational languages
for processing.
Fifth generation computer aims
to be able to solve highly
complex problem including
decision making, logical
reasoning
