Two wires are twisted together to form a pair; the pair form a balanced circuit. The
twisting prevents interference problems, STP provides protection against external
crosstalk.
A cable that wires a pin to its equivalent pin. This cable connects two dissimilar
Straight-through
devices, for example, a data terminal equipment (DTE) device and a data
Ethernet cable
communications equipment (DCE) device. A straight through Ethernet cable is the most
commonly used Ethernet cable.
SUA Single User Account. Your system's SUA feature allows multiple user Internet access
for the cost of a single ISP account. See also NAT.
Subnet Mask The subnet mask specifies the network number portion of an IP address. Your device
will compute the subnet mask automatically based on the IP Address that you entered.
You do not need to change the computer subnet mask unless you are instructed to do
so.
T
TCP Transmission Control Protocol is a connection-oriented transport service that ensures
the reliability of message delivery. It verifies that messages and data were received.
Terminal A device that allows you to send commands to a computer somewhere else. At a
minimum, this usually means a keyboard, display screen and some simple circuitry.
Software that pretends to be (emulates) a physical terminal and allows you to type
Terminal
Software commands to a computer somewhere else.
TFTP Trivial File Transfer Protocol is an Internet file transfer protocol similar to FTP (File
Transfer Protocol), but it is scaled back in functionality so that it requires fewer
resources to run. TFTP uses the UDP (User Datagram Protocol) rather than TCP
(Transmission Control Protocol).
Twisted Pair Two insulated wires, usually copper, twisted together and often bound into a common
sheath to form multi-pair cables. In ISDN, the cables are the basic path between a
subscriber's terminal or telephone and the PBX or the central office.
U
User Datagram Protocol. DP is a connectionless transport service that dispenses with
UDP
the reliability services provided by TCP. UDP gives applications a direct interface with
the Internet Protocol (IP) and the ability to address a particular application process
running on a host via a port number without setting up a connection session.
UNIX A widely-used operating system in large networks. Usually used on workstations and
