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.
