Generations of computers
- 3. We will Discuss Introduction First Generation Computers Second Generation Computers Third Generation Computers Fourth Generation Computers Fifth Generation Computers
- 4. Definition of Computer Computer is an advance electronic device that manipulate information/data. It has the ability to retrieve and process data. It can perform Arithmetic and Logical calculation.
- 8. It starts from 1942-1956. They used Vacuum Tubes as for circuitry and for memory. They were very expensive. They consumed alot of electricity. They were bigger in size, as they occupied a room space UNIVAC and ENIAC computers are examples of first- generation computing 1st Generation Computer
- 10. Limitation Of 1stGeneration Computer They were large in size. They consumed large amount of electricity. Operating of computers were costly. It’s maintenance was costly. It was not portable. They generate a lot of heat.
- 12. 2ndGneration Of Computer The 2nd Generation of computers starts with the development of transistor, It was continued from 1956- 64. They were smaller, faster and cheaper than 1st generation computers. They consumed less electricity due to use of transistor. They generate less heat.
- 13. Limitation of 2nd Generation Computer They were also required cooling system. They were used for specific purpose. They were also very large in size.
- 15. 3rd Generation Computer The third Generations starts with development of IC in 1964 and continued till 1972. They were faster than 1st and 2nd generation computer. They were smaller, cheaper and reliable than 1st and 2nd generation computers. They consumed less electricity.
- 17. Limitation of 3rdGeneration Computer Due to use of IC highly sophisticated technology was required. Still required Cooling system. It was cheaper but not for home use.
- 19. 4th Generation Of Computer This generation starts from1972 to onward. 4th Generation of computer relied on microprocessor which contains thousands of circuits in it. They are smaller, portable, reliable and cheaper. The storage capacity was very much increased. This generation computers were very user user friendly.
- 20. The development of microprocessor revolutionized electronic gadgetry. Smart devices use micro-controllers and are called dedicated computers.
- 24. 5th Generation Of Computer The fifth generation computers are still undergoing development. They will have artificial intelligence They will be able to recognize image, objects and weather forecasting
- 25. They will be able to accept instructions in voice messages, normal conversational languages for processing. Fifth generation computer aims to be able to solve highly complex problem including decision making, logical reasoning
- 27. Activity: Tell the name of following devices.
