FIRST-GENERATION COMPUTERS
The computers that were developed from 1942 to 1955 were called the first-generation computers. These computers used vacuum tube which consists of a glass bulb and wire.The computers were very large, expensive and required huge amounts of electricity. There were called the ENIAC. Link text -

SECOND-GENERATION COMPUTERS
The computers used transistors instead of vacuum tubes.

INVENTION OF ELECTRICITY LED
In the 20th century was the invention of electricity led to the rapid development of computers. -
Period: to
THIRD-GENERATION COMPUTERS
Intergrated circuit were introduced during the development of the third-generation computers. An intergrated circuit is as small as a transistor but it can work as fast as thousands of them. Integrated circuits made computers faster, cheaper, and smaller than the second-generation computers.Link text -
Period: to
FORTH-GENERATION COMPUTERS
The fourth-generation computers use microprocessors. A microprocessor consists of a small silicon chip on which thousands of circuits are placed. The computers are smaller, portable, and cheaper. They use less electricity and produce less heat.Link tex -
Period: to
FIFTH-GENERATION COMPUTERS
Fifth-generatios computers are the future, they are the most advanced computers.Scientists are now trying to develop fifth-generation computers in a way that they can think on their own. This is called Artificial Intelligence. Robots work on this technology.Link text
