  1. 1. SUBMITTED BY ADARSH JAIN Presentation on generation of computer
  2. 2. GENERATION OF COMPUTER MEANS IMPROVEMENT IN THE FIELD OF COMPUTER . What is generation of computer ?
  3. 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. 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. 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. 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. 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. 8. Third generation { 1964 -1971 } The integrated circuits was the hallmark of 3 generation computers .
  9. 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. 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. 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. 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. 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 .
