computer history and latest technology

  1. 1. Presentation on generation of computer <br />Submitted by adarshjainclass : 9 - f<br />
  2. 2. Generation of computer means improvement in the field of computer .<br />What is generation of computer ?<br />
  3. 3. Types of generation of computers <br />There are 5 types of generation of computers :<br />First generation <br />Second generation<br />Third generation <br />Fourth generation<br />Fifth generation <br />
  4. 4. First generation {1940 – 1956}<br />First generation of computers used vaccum tubes for circuitry and magnetic drums for memory . It uses machine language .<br />Eg. Univac & enaic computers <br />
  5. 5. Disadvantage of 1 generation computers <br />They were very large and often takes 1 room .<br />They were very expensive .<br />They uses a large amount of electricity &generate a lot of heat .<br />
  6. 6. Second generation {1956 – 1963}<br />They were invented in 1947 but not see widespread in computers until 1950 . Transistors were used as the second generation computers .<br />In this type of generation computers uses binary machine language or assembly language .<br />
  7. 7. Advantage of 2 generation computers <br />The transistors were superior for vaccum tubes allowing computers to be more faster , cheaper , smaller , etc .<br />These computers for atomic energy industry .<br />
  8. 8. Third generation { 1964 -1971 }<br />The integrated circuits was the hallmark of 3 generation computers .<br />
  9. 9. Advantage of 3 generation computers <br />By the help of integrated circuits transistors were miniaturised & placed on silicon chips called semicondors which increases speed & efficiency of computers .<br />Instead of punch cards it uses keyboards ,monitors & interfaced with an operating system .<br />
  10. 10. fourth generation {1971 - present }<br />The microprocessor was the fourth generation computers .<br />The microprocessor is just like as thousands of integrated circuits (3 generation computer ) built onto a single microchip <br />
  11. 11. Advantage of 4 Generation computers<br />Because of 4 generation more & more every products begin to use microprocessors .<br />Because of 4 generation computer we used to saw development of GUI’s the mouse , & handheld devices .<br />
  12. 12. Fifth generation { Present & Beyond }<br />This generation of computer is the most advance & the best generation of computer till now .This generation is based on artificial intelligence<br />
  13. 13. Advantage of fifth generation of computers <br />Because of artificial intelligence the computer will solve all the equation in nanosecond .<br />The use of parallel processing & superconductors of this generation is helping to make artificial intelligence a reality .<br />
