How many Generations of Computer?

Computer Generation

There are five Generations of Computer

First Generation_____Vacuum Tube

Vaccuum Tube

J.P.Eckert and J.W.Mauchy invent the first successful electronic computer called ENIAC,ENIAC stands for Electronic Numeric Integrated and Calculator.
The first computers used Vacuum tubes for circuitry and magnetic drums for memory.
They were very expensive to operate and in addition to using a great deal of electricity,generated a lot of heat.
First generation computer relied on machine language,the lowest programming language understood by computers to perform calculations,and they could only solve one problem at a time.

Second Generation________Transistor

Transistor

John Bardeen(1908-1991),William B. Shockley(1910-1989) and Walter H invented the second generation of computer technology.
In this generation,transistors were used that cheaper,consumed less power,more impact in size,more reliable and faster than the first generation.
One transistor replaced the equivalent of 40 vacuum tubes.
Still generated a great deal of heat that can damage the computer.

Third Generation________Integrated Circuit

Integrated circuit

Robert Noyce of Fairchild semiconductor and Jack Kilby(American Electrical Engineer) invented the Third Generation of Computer.
The Third Generation of Computer are much faster,efficient,reliable,less maintenance and small size as compared to first and second generation of computers.
The development of the Integrated Circuit was the sign of third generation of computers.

Fourth Generation________Microprocessor

Microprocessor

The first microprocessor was first introduced in 1971 by Intel,invented by their employee Tedd Hoff.
The microprocessor brought the fourth generation of computers,as thousand of integrated circuits were built onto a single silicon chip.
As these small computers became more powerful, they could be linked together to form networks,which eventually led to the development of the internet.
Fourth generation of computers also saw the development of GUIs,the mouse and handheld devices.

Fifth generation_______Artificial Intelligence

Based on Artificial Intelligence(AI).
The fifth generation of computer system was begun by Japan's Ministry of international Trade and Industry.
Still in Development.
The goal is to develop devices that response to natural language input and are capable of learning and self organization.
There are some applications,such as voice recognization,that are being used today.
