A vacuum tube consists of a glass bulb and wire. The wire is use to carry data in the form of elctronic signals. -
The firts-generation computers were very large, expensive, and required huge amounts of electricity. A vacuum tube consists of a glass bulb and wire. The wire is use to carry data in the form of elctronic signals. The ENIAC was a first generation computer.
-
The ENIAC (1946) was the first general-purpose electronic computer, marking the start of modern computing. -
The second-generation computers used transistor instead of vacum tubes.
-
The transistor is a device that replaced vacuum tubes and enabled the creation of smaller and faster computers. -
Integrated circuits combine many electronic components into a single chip, making devices smaller, faster, and more reliable. -
Integrated circuitis made computers faster, cheaper, and samller than the second-generation computers. An integrated circuit (IC) is as samll as a transistor but it can work as fast as thousands of them
-
The microprocessor integrates the CPU into a single chip, making computers smaller and faster. -
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 aduanced 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.

Computers of the future will be faster and smarter, using artificial intelligence, quantum computing, and nanotechnology.
