| DNS | domain name service this service will map a TCP/IP number to a more easily remembered name |
| VPN | (Virtual Private Network) A private network that is configured within a public network. |
| hub | a crnteral connection point standard terminology for a device that connects multiple computers in a network |
| repeater | A communications device that amplifies (analog) or regenerates (digital) the data signal in order to extend the transmission distance. |
| bridge | A device that connects two LAN segments together, which may be of similar or dissimilar types, such as Ethernet and Token Ring. |
| brouter | a brouter is a communication device that functions as both a bridge and a router |
| gateway | a gateway is a protocol converter that supports communication between networks that use different protocols |
| RJ-45 | (Registered Jack-45) A telephone connector that holds up to eight wires |
| Cat 5 | The following categories are based on their transmission capacity. The majority of new wiring installations use Category 5 UTP wire in order to be able to run or upgrade to the faster network technologies that will require it. Categories 1 through 5 are based on the EIA/TIA-568 standard. Levels 6 and 7 are enhanced Category 5 cables and are not yet standardized |
| BNC connector | (Bayonet Neill-Concelman or British Naval Connector) A commonly used plug and socket for audio, video and networking applications |
| fiber optic cable | A thin glass strand designed for light transmission. A single hair-thin fiber is capable of transmitting trillions of bits per second. In addition to their huge transmission capacity, optical fibers offer many advantages over electricity and copper wire |
| network adapter | A printed circuit board that plugs into both the clients (personal computers or workstations) and servers and controls the exchange of data between them. |
| half duplex | The transmission of data in both directions, but only one direction at a time |
| full duplex | Transmitting and receiving simultaneously. In pure digital networks, this is achieved with two pairs of wires. |
| TCP/IP | transmission control protocol/internet protocol is the suite of communications protocols used to connect hosts on the internet and is now the global standard for communications |
| IP address | (Internet Protocol address) The address of a computer attached to a TCP/IP network. |
| IPX | (Internetwork Packet EXchange) A NetWare communications protocol used to route messages from one node to another. IPX packets include network addresses and can be routed from one network to another |
| SPX | (Sequenced Packet EXchange) The NetWare communications protocol used to control the transport of messages across a network. |
| netBEUI | (NetBIOS Extended User Interface) Pronounced "net-booey." The transport layer for NetBIOS. NetBIOS and NetBEUI were originally part of a single protocol suite that was later separated. NetBIOS sessions can be transported over NetBEUI, TCP/IP and SPX/IPX protocols. |
