hub

hub In general, a unit that operates in some sense as the center of a star configuration. In the case of a network, a hub acts as a local concentrator that allows a number of devices, connected to the hub in a star configuration, to connect to a network with an arbitrary configuration. In the special case of an Ethernet network, a hub may refer to a device that provides connection for a number of end-user devices, each using a dedicated twisted-pair (CAT-3 or CAT-5 cables) local connection, to an Ethernet segment running on either a coaxial cable (thick or thin Ethernet) or an optical fiber.

Citation styles

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
