Hub (Network Hub) continued...

Hub (sometimes referred to as a concentrator or repeater Hub) refers to a networking component which acts as a convergence point of a Network allowing the transfer of data packets.

In its simplest form a hub works by duplicating the data packets received via one Port and making it available to all ports, therefore allowing data sharing between all devices connected to the hub.

A passive hub simply allows the data packets to flow through it, a manageable hub allows the data transfer to be monitored and the ports to be configured individually.

There are also switching hubs available, see Switch.
