The summary emphasizes the technological evolution and diversity of computer systems throughout their development.
The Generation of Computers (B6.1.1.1.1)
- 2. B 6 . 1 . 1 . 1 . 1 GENERATION OF COMPUTERS Generation of computers refers to the various stages of development in technology and innovation. The Generations are: First-generation Second-generation Third-generation Fourth-generation Fifth-generation
- 3. B 6 . 1 . 1 . 1 . 1 FIRST GENERATION COMPUTERS (1940 – 1956) •They were based on vacuum tube technology. •These were the fastest computing devices of their times. •They were very expensive to operate. •They used a large amount of electricity. •These computers were very large, and required a lot of space for installation.
- 4. B 6 . 1 . 1 . 1 . 1 SECOND GENERATION COMPUTERS (1956-1963) •They were based on transistor technology. •They were smaller as compared to the first- generation computers. •They were quite portable. •They generated less heat •The frequency of maintenance was less compared to first generation
- 5. B 6 . 1 . 1 . 1 . 1 THIRD GENERATION COMPUTERS (1964 - 1970) •They were based on Integrated Circuit (IC) technology. •They were more portable and more reliable than the second generation. •They consumed less power and produced less heat. •It was smaller as compared to previous computers. •The maintenance cost was quite low.
- 6. B 6 . 1 . 1 . 1 . 1 FOURTH GENERATION COMPUTERS(1970 - 1980) •They are based on VLSI technology -microprocessor •These computers generate very small heat •They are the cheapest among all the other Gen. •They are portable and quite reliable. •These computers are very small. •Production cost is very low. •Power consumption is very low
- 7. B 6 . 1 . 1 . 1 . 1 FIFTH GENERATION COMPUTERS (1980 - DATE) •They are based on Artificial Intelligence (AI) •Computers that are more portable and powerful. •Computers are dependable and less expensive. •Advancement in Parallel Processing •More user-friendly interfaces with multimedia features
- 8. B 6 . 1 . 1 . 1 . 1 CLASSIFICATIONS OF COMPUTERS : SIZE •Another way of classifying computers aside their generation is by classifying them according to their SIZES & CAPACITY: •Supercomputer. •Mainframe computer. •Minicomputer. •Microcomputer
- 9. B 6 . 1 . 1 . 1 . 1 CLASSIFICATIONS OF COMPUTERS : SIZE Supercomputers are very fast: •It can calculate up to ten trillion individual calculations per second. •It is used in scientific research areas for analyzing data.
- 10. B 6 . 1 . 1 . 1 . 1 CLASSIFICATIONS OF COMPUTERS : SIZE Mainframe is also an expensive or costly computer. •It has high storage capacity and great performance. •It can process a huge amount of data (like data involved in the banking sector) very quickly.
- 11. B 6 . 1 . 1 . 1 . 1 CLASSIFICATIONS OF COMPUTERS : SIZE Minicomputer is a medium size multiprocessing computer. •Its weight is low. •Minicomputers are used in places like institutes or departments. •It is less expensive than a mainframe computer.
- 12. B 6 . 1 . 1 . 1 . 1 CLASSIFICATIONS OF COMPUTERS : SIZE Microcomputer is designed for personal use (PC). •It is the smallest in size. •It is easy to use. •It consists of a microprocessor as a Central Processing Unit(CPU) •Uses limited number of software
