TN3270:
A variant of the Telnet program that allows users to attach to IBM mainframes and use the mainframe as if
they had a 3270 or similar terminal.
Token Ring:
A token ring is a type of LAN with nodes wired into a ring. Each node constantly passes a control
message (token) on to the next; whichever node has the token can send a message. Often, "Token Ring" is used to
refer to the IEEE 802.5 token ring standard, which is the most common type of token ring.
Topology
: A network topology shows the computers and the links between them. A network layer must stay abreast
of the current network topology to be able to route packets to their final destination.
Transceiver:
Transmitter-receiver. This is the physical device that connects a host interface to a network, such as
Ethernet. Ethernet transceivers contain electronics that apply signals to the cable and sense collisions. Transceivers
are generally associated with a piece of network gear (e.g. repeater, bridge, workstation).
Transit Network:
A transit network passes traffic between networks in addition to carrying traffic for its own hosts. It
must have paths to at least two other networks.
Trojan Horse:
A computer program that carries within itself a means to allow the creator of the program access to the
system using it. See also: Virus and Worm.
TSO:
Telecommunications Services Outlet. This is a "wall jack" or faceplate in an office, lab, or other work area.
Tunneling:
Tunneling refers to encapsulation of protocol A within protocol B, such that A treats B as though it were a
data link layer. Tunneling is used to get data between administrative domains that use a protocol that is not supported
by the Internet that connects those domains.
Twisted Pair:
A wiring scheme that uses standard pairs of copper wires. Twisted pair might be used for normal
telephone connections or serial data.
Twisted Pair Ethernet:
Ethernet running over twisted pair wiring. Ethernet can also run over a variety of other media.
Twisted Pair Hub:
An Ethernet device, typically with 8 twisted pair ports and one transceiver cable port.
U
UDP:
User Datagram Protocol. An Internet Standard transport layer protocol defined in STD 6, RFC 768. It is a
connectionless protocol that adds a level of reliability and multiplexing to IP. See also: Connectionless and TCP.
UNIX:
Popular multi-user operating system for scientific workstations and file and database servers.
URL:
Universal Resource Locator, used in World-Wide Web (WWW).
Usenet:
A collection of thousands of topically named newsgroups, the computers that run the protocols, and the
people who read and submit Usenet news. Not all Internet hosts subscribe to Usenet and not all Usenet hosts are on
the Internet. See also: NNTP, UUCP.
UTC:
Universal Time Coordinated. This is Greenwich Mean Time.
UUCP:
UNIX-to-UNIX Copy. This was initially a program run under the UNIX operating system that allowed one UNIX
system to send files to another UNIX system via dial-up phone lines.
Today, the term is more commonly used to describe the large international network that uses the UUCP protocol to
pass news and electronic mail. See also: Electronic Mail, Usenet.
