T1: An AT&T term for a digital carrier facility used to transmit signals at 1.544Mb/sec. The fiber links between many network nodes run at T1 speed; in some areas, you can get T1 service into your local home or office.
T-1 Circuit: A type of leased phone line. A T-1 circuit 1,544,000 bits per second which is equivilent to 24 56kbs leased lines.
T3: A term for a digital carrier facility used to transmit signals at 44.746Mb/ sec. The NETCOM backbone fiber runs at T3 speed.
T-3 Circuit: A type of leased phone line. A T-3 Circuit (45,000,000 bits per second) is the backbone speed of all major national Internet Service Providers in the US. and roughly equivilent to 30 T-1 lines
Talk: A protocol that allows two people on remote computers to communicate in a real-time fashion.See also Internet Relay Chat.
tape archive: Permanent storage of files on magnetic tape, usually used for backup of files, from a computer.; Return to Index

TCP: See Transmission Control Protocol.
TCP/IP Protocol Suite: A common shorthand that refers to the suite of transport and application protocols that runs over the Internet. TCP/IP (Transmission Control Protocol over Internet Protocol) is the set of rules which defines the communications standards for passing information back and forth across the Internet. TCP/IP is actually a collection of more than 100 transmission protocols. It is the common language that controls all communications hardware linked to the Internet,thereby helping to avoid communications conflicts and misunderstandings when data is shuttled among computers linked to the Internet. See also Internet Protocol, Transmission Control Protocol, File Transfer Protocol, Telnet, Simple Mail Transfer Protocol.
Telenet: A public packet-switched network using' the CCITT X.25 protocols. It should not be confused with Telnet. In the United States the network is called SprintNet. Telenet/SprintNet is one of the largest IP networking vendors and offers direct connections and high-speed links.
Telnet: A text based networking utility that allows your computer to emulate a terminal connected to a particular network. Unlike FTP, which only allows you to access files from a remote computer, Telnet actually allows you to log into a network and run programs and other services available on the network.Telnet is the Internet standard protocol for remote terminal connection service.
terminal emulator: A program that allows a computer to emulate a particular type of terminal in order to communicate with a remote host computer that is programmed to work with terminals of that type.
terminal server: A device that connects many terminals to a LAN through one network connection. A terminal server can also connect many network users to its asynchronous ports for dial-out capabilities and printer access. See also Local Area Network.
text file: A file that can be read by a human and one that can be transmitted between different programs and systems containing no graphics or formatting information, see ASCII character.
Thirty-ninety (3090): a Mainframe (IBM 3090).
TIFF: Tagged Interchange File Format, a graphics format mutually established by Adobe and Microsoft for use in importing graphics into different applications. TIFF is a common graphics standard among PC applications, but can't be used with some GIF/JPEG viewers.
time sharing: an old system where people were allotted chunks of time on a large computer
TN3270: A variant of the Telnet program that allows one to attach to IBM mainframes and use the mainframe as if you were using a 3270 (or similar) terminal. IBM 3270 terminals (and terminal emulators) are noted for having fullscreen displays, instead of line-oriented displays, and frequently have fixed fields or cells in the display where information can be entered and updated. Several popular library card catalog interfaces work best with TN3270 emulators.
Transfer Protocol: In a URL, this identifies the set of standard transfer procedures that will be used to access and exchange information on the Internet and the Web. Examples of transfer protocols are http and ftp. A transfer protocol is an example of a resource type.
Transmission Control Protocol (TCP): An Internet standard transport layer protocol that is connection-oriented and stream-oriented.
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, worm.
Trumpet Winsock: Widely used utility for TCP/IP stack implementation for windows.
twisted pair cable: ethernet cable that looks like a normal RJ11 telephone wire.
