Electricity led
The invention of electricity led to the rapid development of computers in the 20th century. -
Vacuum tubes
A vacuum tubes consist of a glass bulb and wire. The wire is used to carry data in the form of electronic signals. -
Period: to
First-generation computers
The computers that were developedfrom 1942 to 1955 were called the first generation computers.
The first generation computers were very large, expensive and required huge amounts of electricity. -
ENIAC
The eniac was the first electronic general-purpose computer. -
Period: to
2nd GENERATION COMPUTERS
The second-generation computers used transistors instead of vacuum tubes.

3rd GENERATION COMPUTERS
In this generation included an integrated circuit (IC) is a small as a transistor but it can work as fast asnthousands of them. Integrated circuits made computers faster, cheaper and smaller than the second generation computers.

4th GENERATION COMPUTERS
the fourth-generation computers use a microprocessors. A microprcessor consist of a small silicon chip on which thousans of circuits are placed. The computers are smaller, portable, cheaper, they use less electricity and produce less heat.

5th GENERATION COMPUTERS
Scientist are now trying to developed fifth-generation computers in a way that we can think on their own. This is called Artificial inteligent (AI). Robots work on this technology.
