5. 1st Generation
Of Computer

6. 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

7. 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.

8. 2nd Generation
Of
Computer

9. 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.

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

11. 3rd Generation
Of
Computer

12. 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.

13. 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.

14. 4th Generation
Of
Computer

15. 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.

16. 5th Generation
Of
Computer

17. 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
