Definition of Computer
Computer is a advance electronic device
that manipulate information/data. It has
the ability to retrieve and process data.
It can perform Arithmetic and Logical
calculation.

1st Generation
Of Computer
![Page 6: Generations Of Computer](https://reader031.fdocuments.net/reader031/viewer/2022032113/55a5e2fc1a28ab23368b4631/html5/thumbnails/6.jpg)
1st Generation Computer
The first generation computers were from 1940-156.
It was made up of Vacuum Tubes which were used for circuitry
and for memory.
It was expensive to operate.
It consumed lots of electricity.
It was bigger in size , it occupied a room space
Due to vacuum tubes it generate lot of heat.
UNIVAC and ENIAC computers are examples of first-generation computing
It was developed by two scientists Mauchly and Echert

Limitation Of 1st Generation Computer
It was large in size.
It consumed large amount of electricity.
Operating of computers were costly.
It’s maintenance was costly.
It was not portable.

2nd Generation
Of
Computer
![Page 9: Generations Of Computer](https://reader031.fdocuments.net/reader031/viewer/2022032113/55a5e2fc1a28ab23368b4631/html5/thumbnails/9.jpg)
2nd Gneration Of Computer
Due to technology of transistor in 1947 at Bell lab ,it lead
to development of 2nd Generation of computers.
It was continued from 1956-64.
It was made up of transistors.
It was better than 1st generation computers.
It was faster than previous computers.
It consumed less electricity due to use of transistor.

Limitation of 2nd Generation Computer
It was required cooling system.
It was only for specific purpose.
It was costly.
It was not portable.

3rd Generation
Of
Computer
![Page 12: Generations Of Computer](https://reader031.fdocuments.net/reader031/viewer/2022032113/55a5e2fc1a28ab23368b4631/html5/thumbnails/12.jpg)
3rd Generation Computer
Due To development of IC in 1958-59 By Noyce and
Kilbay lead to development of Third Generation
Computer.
It was continued from 1964-72.
It was faster than other generation computer
It’s speed was in nanosecond.
It was smaller in size.
It was portable.
It consumed very less electricity.

Limitation of 3rd Generation Computer
Due to use of IC highly sophisticated technology was
required.
Still required Cooling system.
It was cheaper but not for home use.

4th Generation
Of
Computer
![Page 15: Generations Of Computer](https://reader031.fdocuments.net/reader031/viewer/2022032113/55a5e2fc1a28ab23368b4631/html5/thumbnails/15.jpg)
4th Generation Of Computer
It was from 1972-84.
This generation of computer used Large Scale Integration(L.S.I.) and Very Large
Scale Integration(V.L.S.I.).
The storage capacity was very much increased.
This generation computers were very user user friendly.
Processing speed was 1 billion instruction per second.
Comparatively smaller in size and greater reliability.

5th Generation
Of
Computer
![Page 17: Generations Of Computer](https://reader031.fdocuments.net/reader031/viewer/2022032113/55a5e2fc1a28ab23368b4631/html5/thumbnails/17.jpg)
5th Generation Of Computer
The fifth generation computers will use super large scale integrated chips.
They will have artificial intelligence
They will be able to recognize image and graphs.
They will be able to use more than one CPU for faster processing
speed.
Fifth generation computers are intended to work with natural
language.
Fifth generation computer aims to be able to solve highly complex problem including decision making, logical reasoning
