RJ-45 CONNECTOR
A connector for twisted-pair wiring.
SWITCHED PORTS
Ports that are on separate collision domains or LAN
segments.
TIA
Telecommunications Industry Association.
TRANSMISSION
CONTROL
PROTOCOL/INTERNE
T 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 the packet-switched
communications. It uses the IP as the underlying
transport mechanism to provide access to IP-like services.
UDP packets are delivered just like IP packets –
connection-less data grams 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.
VIRTUAL LAN
(VLAN)
A Virtual LAN is a collection of network nodes that share
the same collision domain in regardless of their physical
location or connection point in the network. A VLAN
serves as a logical workgroup with no physical barriers,
allowing users to share information and resources as
though located on the same LAN.
