What is Generation of Computer
The History of Computer development is often referred to the different generation of computer device. Each computer generation is characterising by a better technology that change the way of computer operator, configuration, more powerful, efficient , and reliable.
First Generation (1948-1955) [Vacuum tube]
Invented by J.P.Eckert and J.W. Mauchy
The first generation computer used vacuum tubes, a fragile glass device, which used filaments as a source of electronics and could control and amplify electric signals
Features of First Generation
- At that time ,it was the fastest calculating device.
- It was also large in size and required large room for installation.
- Thousand of vacuum tubes are used that produce large amount of heat,So it was installed where in cool place .
- Power consumption ar very high
- These computer are require large amount of compoments
- Input are based on punched cards and paper tape ,and out put was displayed on printout.
Example of first Generation of Computer
ENIAC,EDVAC & UVIVAC
Second Generation (1955-1964)[Transistor ]
Invented by J.Bardeen ,W. Shockley & W.Brattain
In this generation were used transistor.Transisitor invented in 1947 & these became replace ment of vacuum tubes.
Feature of second generation
- They were much faster of the Second generation computer
- These were of a smaller size and thus require less space
- They were easier to programme and hence had a wider use in commercial places.
- These computer too required lot of component to be assembled manually hence it was difficult to have large production
Third Generation (1964-1975)[Integrated Circuit (I.C)]
Invented by Jack St. Clair Kilby & Robert Noyce
IC invented in 1958 and also other components .These computer is reliable and smallest. Integrated circuit developed in this generation of computer
Feature of third generation
- These are more powerful than second generation computer
- Cable performing about Million instruction per second
- It smaller than second generation of computer
- Require less space
- It was faster and larger primary and secondary storage device compare to upper version
- Suitable for both commercial and scientific use
- Batch operating was replaced by time sharing system
Example of third generation of computer
IBM 3608370,CDC6600, Etc
Fourth Generation (1975-1989)
[ Microprocesss ]
Invented by Macintosh
This generation of computer are better service another previous generation computer .in 1981,IBM introduced its fast computer for the home user. It did not require much air-conditioning and uses less electricity .It generate less heat.
Feature of Fourth Generation
- CRT screen, laser and inject printer, scanners, etc where developed.
- LAN and WANS were developed
- Semiconductor memory chips were used as a main memory
- Secondary memory was composed of hard disks
- Introduce graphics user interface
- Operations became much faster
- High performance ,lower cost and very compact in size
Fifth Generation (1989)
[Artificial intelligence ]
A vast ocean of information has become readily available to computer users through the World Wide Web.
Feature of fifth generation
- Portable laptops are much smaller and easy to handle than fourth generation computer.
- It is less power consumption
- They much faster & have large storage both primary and secondary
- With the usage of the ULSI (Ultra large scale integration)
- These computer can be made short periods of time
- Being cheaper ,more people are buying and using them.
Six generation of computer (2016)
[voice recognition]
In this generation improved the motherboard and silicon footprint decreases and the speed, power and memory power increases. Transistors opened the door to faster processing
7th Genation of computer (2017)
- Core Up to 4K UHD video streaming
- All Day 4K battery life (9.5hr)1
- 4 hours video battery life2
- 75X longer video battery life (7hr)2 View multiple video streams simultaneously, up to 4K
- Support for additional formats of 4K 360 content streams….more
