What is a hub

A hub is used in a wired network to connect Ethernet cables from a number of devices together. The hub allows each device to talk to the others. Hubs aren't used in networks with only wireless connections, since network devices such as routers and adapters communicate directly with one another.

Hubs are such simple devices — they require no configuration, and have no manuals — that their function is now included in other devices such as routers and modems. If you require a stand-alone appliance, use a switch instead. Switches provide better performance and features than hubs.
