A network is two or more computers, or other electronic devices, connected together so that they can exchange data.

For example a network allows computers to share files, users to message each other, a whole room of computers to share a single printer, etc.

Network connections between computers are typically created using cables (wires). However, connections can be created using radio signals (wireless / wi-fi), telephone lines (and modems) or even, for very long distances, via satellite links.
A computer that is not connected to a network is known as a standalone computer.
