Network Hubs

Definition : Computerized network devices designed exclusively to establish paths between computers and/or computer peripherals, providing communication channels between them. These devices typically consist of simple electronic units with circuits that permit the use of multiple computers in a common local area network (LAN); most network hubs support the Ethernet standard but other types exist (e.g., USB [Universal Serial Bus] hubs used mainly with computer-associated peripheral devices such as printers and scanners). Network hubs include multiple ports (typically from 4 to 16); hubs may be connected each other and also to routers and/or switches to accommodate more devices. By delivering each message only to the device for which it is intended, a network hub facilitates the use of multiple computers and peripherals together in the same LAN.
