network.

T
TCP/IP (Transmission Control Protocol/Internet Protocol) - Set of protocols designed to link dissimilar computers that use various networks and LANs.
Topology - Geometric physical or electrical configuration that describes a local communication network. The most common distribution system topologies are the bus, ring, and star.
U
UDP (User Datagram Protocol) - A protocol within the TCP/IP protocol suite. When reliable delivery is unnecessary, communications may use UDP instead of TCP.
UBR (Unspecified Bit Rate) - Best effort service that does not require tightly constrained delay and delay variation. UBR provides no specific quality of service or guaranteed throughput.
USB (Universal Serial Bus) - External bus standard that supports data transfer rates of 12 Mbps.
V
VCI (Virtual Channel Identifier) - Address of a virtual circuit. An integer that ranges from 0 to 65,535. The integer identifies a virtual channel that cells may traverse.
VPI (Virtual Path Identifier) - Address of a virtual path to a connection on an ATM network. An integer that ranges from 0 to 4,095.
W-X-Y-Z
WAN (Wide Area Network) - Network base that covers a large geographic area.
