| passive Hub | simply forwards network messages |
| repeater(active hub) | regenerates and amplifies the data bits in order to maintain a strong signal that might otherwise deteriorate over a long distance. |
| bridge | controls the blow of information between LAN segments or networks, even if they are different types of networks using differnt communication protocols |
| brouter | a comm device that functions as both a bridge and a router |
| gateway | a protocol converter that supports comm between networks that use diff protocols |
| RJ-45 | connector with eight wires that is used to connect computers onto LANs that use twisted-pair cabling |
| Cat 5 | type of cabling that consists of four twisted-pairs of copper wire terminated by RJ-45 connectors. can be used for token ring, 1000baset, 100baset, and 10baset networking |
| BNC connector | the type of connector most commonly used to join coax cables in a network |
| fiber-optic cable | a cable that transfers pulses of light instead of electrical signals |
| network adapter | a printed circuit board that plugs into both the clients and servers and controls the exchange of data between them |
| half duplex | comm type in which comm can occur in two directions, but only in one direction at a time |
| full duplex | comm type in which comm can occur in two directions at the same time |
| tcp/ip(transmission control protocol/internet protocol) | the protocol suite used to connect hosts on the internet and other networks |
| IP address | a unique 4-byte number that indentifies a node on a TCP/IP network. commonly written in dotted decimal format, such as 128.0.0.1 |
| IPX(internetwork packet exchange) | a netware comm protocol used to route messages from one node to another |
| SPX(sequenced packet exchange) | the netware comm protocol u sed to control the transport of messages across a network |
| NetBEUI(netbios enhanced user interface) | the default networking protocol for the windows desktop OS |
| VPN(virtual private network) | a private network that is configured within a public network |
| DNS(domain name service) | this service will map a TCPIP # to a more easily remembered name |
