A group of connected computers located in a single geographic areausually a building or office that share data and services.

A type of printer that uses electrophotography as the means of printing images on paper.

The delay induced by a piece of equipment or device used to transfer data.

Media connector used with fiber-optic cabling.

Protocol used to access and query compliant directory services systems such as Microsoft Active Directory or Novell Directory services.

A bridge that builds its own bridging address table rather than requiring someone to enter information manually. Most modern bridges are learning bridges. Also called a smart bridge.

An older computer system or technology.

A device used to stabilize the flow of power to the connected component. Also known as a power conditioner or voltage regulator.

An LED on a networking device such as a hub, switch, or NIC. The illumination of the link light indicates that, at a hardware level, the connection is complete and functioning.

A dynamic routing method in which routers tell neighboring routers of their existence through packets called link-state advertisements (LSAs). By interpreting the information in these packets, routers can create maps of the entire network. Compare with distance-vector routing.

A UNIX-like operating system kernel created by Linus Torvalds. Linux is distributed under an open-source license agreement, as are many of the applications and services that run on it.

A sublayer of the data-link layer of the OSI model. The LLC layer provides an interface for the network-layer protocols and the MAC sublayer.

The addressing method used in providing manually assigned node addressing.

The appearance of the network to the devices that use it, even if in physical terms the layout of the network is different.

A continuous circle that a packet takes through a series of nodes in a network until it eventually times out.

A device used for loopback testing.

A troubleshooting method in which the output and input wires are crossed or shorted in a manner that allows all outgoing data to be routed back into the card.

Service on a system (normally UNIX or Linux) that acts as a print server. Print jobs are submitted to the LPD application using a protocol such as LPR.

Network service that allows printing jobs to be sent to a remote print service such as LPD.

An open standard that allows both high storage capacity and fast data access in tape backup systems.
