2. Generation of computer means improvement in the field of computer . What is generation of computer ?

3. Types of generation of computers There are 5 types of generation of computers : First generation Second generation Third generation Fourth generation Fifth generation

4. First generation {1940 – 1956} First generation of computers used vaccum tubes for circuitry and magnetic drums for memory . It uses machine language . Eg. Univac & enaic computers

5. Disadvantage of 1 generation computers They were very large and often takes 1 room . They were very expensive . They uses a large amount of electricity &generate a lot of heat .

6. Second generation {1956 – 1963} They were invented in 1947 but not see widespread in computers until 1950 . Transistors were used as the second generation computers . In this type of generation computers uses binary machine language or assembly language .

7. Advantage of 2 generation computers The transistors were superior for vaccum tubes allowing computers to be more faster , cheaper , smaller , etc . These computers for atomic energy industry .

8. Third generation { 1964 -1971 } The integrated circuits was the hallmark of 3 generation computers .

9. Advantage of 3 generation computers By the help of integrated circuits transistors were miniaturised & placed on silicon chips called semicondors which increases speed & efficiency of computers . Instead of punch cards it uses keyboards ,monitors & interfaced with an operating system .

10. fourth generation {1971 - present } The microprocessor was the fourth generation computers . The microprocessor is just like as thousands of integrated circuits (3 generation computer ) built onto a single microchip

11. Advantage of 4 Generation computers Because of 4 generation more & more every products begin to use microprocessors . Because of 4 generation computer we used to saw development of GUI’s the mouse , & handheld devices .

12. Fifth generation { Present & Beyond } This generation of computer is the most advance & the best generation of computer till now .This generation is based on artificial intelligence

13. Advantage of fifth generation of computers Because of artificial intelligence the computer will solve all the equation in nanosecond . The use of parallel processing & superconductors of this generation is helping to make artificial intelligence a reality .
