Computer Generation - Generation is computer terminology is a change in technology a computer was being used . The generation term used to distinguish between varying hardware technology. But now a days generation include both hardware and software, which together make up an entire computer system.
There are five types of generation-
1- First generation [1946-1959]- the first generation of computer started with using vacuum tubes as the basic components for memory . But these tube like your electric bulb produced much heat . They were very expensive and small organisation could not afforded easily.
In this generation I/o devices such as punched cards, paper tapes, magnetic tape are used.
The main feature of this generation are -
- Vacuum tube technology
- large size
- costly
- unreliable
- generate much heat.
- non portable.
2- Second Generation [1959- 1965]- In this generation transistors were used. They were cheaper, consumed less power also more reliable then first generation. In this generation primary storage is magnetic tapes and magnetic disk as a secondary storage
The main feature of this generation-
- transistor used.
- faster, generate less heat, not so much larger size, consumed less electricity then the first generation.
- More reliable then the first generation
- supported assembly and machine language.
3- Third generation [1965- 1971]- In this 3rd generation integrated circuit are used. Transistor are replace with the IC(integrated circuit). In single integrated circuit has many transistor, resistor and capacitor. In this generation multiprogramming, real time and time sharing operating system are used.
The main features are-
- Integrated circuit are used
- More reliable then the first two generation.
- less maintenance
- consumed less electricity, faster, generate less heat the the first two generation.
- but still very costly.
4- Fourth generation- [1971-1980] - In this generation VLSI circuit was used. VLSI or very large scale integration circuit having about 5000 transistors and other circuit elements on a single chip. It is possible to made it to have a microcomputer of fourth generation.
The main feature of this generation are-
- use of VLSI technology.
- Reliable, very small size, portable then the other first three generation.
- in this generation internet concept were used or great development in the field of network.
- very cheap then the other three generation.
5- Fifth Generation - [1980 to Till date] - In this generation ultra large scale integration [ULSI] technology used. In this microprocessor chip having ten million electronics components.
The main feature of this generation are-
- ULSI technology used.
- all higher level language used in this.
- development in area of Artificial intelligence which include Robotics, Game playing, Neural N/w.
- user friendly.
