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.
VIRTUAL LAN (VLAN)
A Virtual LAN is a collection of network nodes that share the same collision
domain 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.
