MODAL BANDWIDTH
Bandwidth for multimode fiber is referred to as modal bandwidth because it
varies with the modal field (or core diameter) of the fiber. Modal bandwidth is
specified in units of MHz per km, which indicates the amount of bandwidth
supported by the fiber for a one km distance.
NETWORK DIAMETER
Wire distance between two end stations in the same collision domain.
RJ-45 CONNECTOR
A connector for twisted-pair wiring.
SWITCHED PORTS
Ports that are on separate collision domains or LAN segments.

TRANSMISSION CONTROL PROTOCOL/INTERNET PROTOCOL (TCP/IP)
Protocol suite that includes TCP as the primary transport protocol, and IP as the
network layer protocol.
USER DATAGRAM PROTOCOL (UDP)
UDP provides a datagram mode for packet-switched communications. It uses IP
as the underlying transport mechanism to provide access to IP-like services.
UDP packets are delivered just like IP packets – connection-less datagrams that
may be discarded before reaching their targets. UDP is useful when TCP would
be too complex, too slow, or just unnecessary.
UTP
Unshielded twisted-pair cable.
