The first generation computers were very large, expensive, and required huge acounts of electricity.
-
A vacum tube consist of a glass bulb and wire. The wire is use to carry data in the form of electronic signals. The ENIAC is the first computer in the first generation. -
The ENIAC is the first computer in the first generation. -
The second generation computers used transistors instead of vacum tubes.
-
Transistors are electronic conponents that control the flow of electricity and enable computers to funcion. -
Integrated circuits made computers faster, cheaper and smaller than the second generation computers.
An integrated circuit (IC) is as small as a transistor but it can work as fast as thousands of them. -
A miniature electronic circuit that combines numerous interconnected electronic components like transistors, resistors, and capacitors onto a single semiconductor chip, often silicon. -
The fourth generation computers are smaller, portable and cheaper. They use less electricy and produce less heat.
The fourt generation computers use microprocessors. -
A microprocessor consists of a small silicon chip on which thousands of circuits are placed. -
The fifth generation computers are the most advanced computers.
Scientists are now triying to develop fifth generation computers in a way that they can twink on their own. This is called artificial inteligence (AI). Robots work on this tecnology. -
Supercomputers are the most complex computers. They are used by people who need to process complex and large amounts of data.
