A vacuum tube consists of a glass bulb and wire. The wire is use to carry data in the form of electronic signals. -
The first-generation computers were very large, expensive, and requiered huge amounts of electicity. The ENIAC was a frist-generation computer.
-
ENIAC was the first general-purpose electronic computer. It was enormous, used vacuum tubes, consumed a lot of energy, and was programmed with wires. -
Transistors are electronic components that control the flow of electricity and enable computers to function. -
The second-generation computers used transistors instead of vacuum tubes.
-
Integrated circuits are chips that group many transistors into one, making computers smaller, faster and cheaper. -
Integrated circuitis 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
-
The microprocessor is a chip that acts as the ‘brain’ of the computer, executing instructions and controlling the entire operation of the system. -
The fourth-generation computers are smaller, portable and cheaper. They use less electricity and produce less heat. The fourth-generation computers use microprocessors. A microprocessors 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 trying to develop fifth-generation computers in a way that they can think on their own. This is called artificial inteligence (AI). Robots work on this technology. Supercomputers are the most complex computers. They are used by people who need to process complex and large amounts of data

The computers of the future will be faster, smarter, and capable of solving complex problems.
