Switch

SWICH /swɪtʃ/
nounB2
technicalgeneral

A networking device that connects devices on a computer network by using packet switching to receive, process, and forward data to the destination device.

More intelligent than a hub, a switch directs data only to the intended recipient within a local network, improving efficiency.

The story behind the word. The word 'Switch' comes from the Old English 'swic,' meaning 'a sudden movement' or 'a trick.' Over time, it evolved to describe a mechanical device that changes the path of an electrical circuit. In networking, a switch performs a similar function: it intelligently 'switches' or directs data packets from one port to another, ensuring they reach the correct destination device within a local network. It's all about making the right connection.
