TCP (Transmission Control Protocol)
A method (protocol) used with the IP to send data in the form of message units
(datagrams) between network devices over a LAN or WAN. While IP handles the actual
delivery of the data (routing), TCP keeps track of the individual units of data (packets) that
a message is divided into for efficient delivery over the network. TCP requires the receiver
of a packet to return an acknowledgment of receipt to the sender of the packet.
TCP/IP (Transmission Control Protocol/Internet Protocol)
The basic communication language or set of protocols to communicate over a network
(developed specifically for the Internet). TCP/IP defines a suite or group of protocols.
TDMA (Time Division Multiple Access)
A method in which cable modems must time-share the upstream channel because there
are many cable modems and only one upstream channel frequency.
TFTP (Trivial File Transfer Protocol)
A file transfer protocol used to transfer automatically configuration or boot files.
TPC (Transmit Power Control)
Sometimes called Dynamic Power Control (DPC), TPC is a mechanism used in radio
communications to reduce the power of a radio transmitter to the minimum necessary to
maintain the link with a certain quality. It is used to avoid interference with other devices
and/or to extend battery life.
UDP (User Datagram Protocol)
A communications protocol that offers a limited amount of service when messages are
exchanged between computers in a network that uses the Internet Protocol.
UPNP (Universal Plug and Play)
A set of networking protocols that permits networked devices to seamlessly discover each
other's presence on the network to enable data sharing, communications, and
entertainment.
Upstream
A term to describe the direction of data from the customer to the network service provider.
URI (Uniform Resource Identifier)
A string of characters used to identify a name or a resource on the Internet.
URL (Uniform Resource Locator)
A uniform resource identifier (URI) that specifies where a known resource is available and
how to retrieve it.
WAN (Wide Area Network)
A long-distance link or computer network that spans a relatively large geographical area
that connects remotely located LANs. Typically, a WAN consists of two or more LANs.
