Glossary of Terms
Baseband - A transmission method where the entire line is used as a single channel for transmission.
Bridges - An internetworking device that provides a communication pathway between two or more network
segments or sub networks.
CAT-5 – (Category 5) – Cable type standard used in 100Mbps transmission. See also Shielded Twisted Pair.
CSMA/CD - Carrier Sense Multiple Access with Collision Detection - The network access control method
used in Ethernet.
DHCP – Dynamic Host Configuration Protocol. Software service that dynamically provides IP addresses to
devices attached to an Ethernet network.
Ethernet - Networking system originally developed by DEC, Intel and Xerox. Ethernet has 10Mbps
throughput and uses a carrier-sensing access method in which workstations share a network cable, but only
one can use the cable at a time.
Exclusion – In a DHCP server, a range of addresses within a scope that will not be issued, typically because
they are to be used by devices using fixed IP addresses.
Fast Ethernet - IEEE standard for High speed 100Mbps Ethernet.
Hub - A generic term for the central point of connection for the wires from workstations and nodes. Data on
any port is duplicated on all ports Also, see Switch.
IEEE - Institute of Electrical and Electronic Engineers, the standards body that creates the Networking
specifications.
IP Address – Internet Protocol Address. A standardized naming convention used to uniquely identify
devices attached to a network.
LAN - A common abbreviation of Local Area Network.
Local Area Network - A system of hardware and software connected by a common media that allows for
sharing and or transferring data between computing devices.
Media - That which acts to connect the various hardware components that make up a LAN. Media largely
refers to the cable or wires in a typical wired LAN.
Network Interface Card - A specific type of adapter that allows for hardware connection to LAN media.
NFS - Network File System. A communication protocol used to transfer messages, or data, over the Ethernet
with a server.
NIC - A common abbreviation for Network Interface Card. A device that connects to the expansion slot of a
system and allows hardware connection to LAN media.
Node - Any computing device (i.e. PC server, or DigiCart/E recorder) connected to a LAN.
