Packet
A group of bits in a defined format, containing a data
message that is sent over a network.
Protocol
A set of rules that machines must follow to exchange
information on a network.
Primary Domain Controller
A device that manages the common security policy and
user account databases for a group of NetBIOS servers.
The election protocols are such that the primary domain
controller has a tendency to become the master browser.
Remote Collision
A collision that occurs on the other side of a repeater.
Since a 10BASE-T Hub is a multi-port repeater with a
"segment" dedicated to each station, 10BASE-T
collisions are remote collisions.
Repeater
A repeater is a layer-1 device that regenerates and
retimes frames.
RJ-45 Connector
A modular connector used for UTP wiring. The RJ-45
connector has eight conductors to accommodate four
pairs of wires, and it has become the dominant connector
used in Ethernet and Token Ring UTP installations.
Router
A router is a network-layer device that connects
networks using like network-layer protocols. Routers can
span different network topologies. For example, a router
can interconnect Token Ring and Ethernet Novell
NetWare networks. For a router to pass traffic, unlike a
bridge, it must be configured for the desired protocol.
Routers are more difficult to configure but offer greater
security.
Runts
Typically defined as a Ethernet frame which is less than
64 bytes. Depending on what device is counting the
runts, the frame check sequence may be good or bad.
SAP (Service Advertising Protocol)
A NetWare protocol used to request and broadcast
information about file servers, print servers, and other
services on a network.
