teletypewriter exchange service (TWX) n. Teletypewriter service in which suitably arranged teletypewriter stations are provided with lines to a central office for access to other such stations throughout the U.S. and Canada. Both baudot- and ASCII-coded machines are used. Business machines may also be used, with certain restrictions.
Telnet n. In the Internet suite of protocols, a protocol that provides remote terminal connection service. It allows users of one host to log on to a remote host and interact as directly attached terminal users of that host.
tent card n. A rectangular card, folded down the middle lengthwise, on which a name is written to identify a participant at a meeting.
terabit (Tb) 1. n. For processor storage, real and virtual storage, and channel volume, 240 or 1 099 511 627 776 bits. 2. n. For disk storage capacity and communications volume, 1 000 000 000 000 bits.
terabyte (TB) 1. n. For processor storage, real and virtual storage, and channel volume, 240 or 1 099 511 627 776 bytes. 2. n. For disk storage capacity and communications volume, 1 000 000 000 000 bytes.
terminal n. A device, usually equipped with a keyboard and a display device, that is capable of sending and receiving information.
terminal emulator n. A program that allows a device such as a microcomputer or personal computer to enter and receive data from a computer system as if it were a particular type of attached terminal.
Test ("test for df 2") test number2
thin client n. A client that has little or no installed software but has access to software that is managed and delivered by network servers that are attached to it. A thin client is an alternative to a full-function client such as a PC.
time stamp 1. v. To apply the current system time. 2. n. The value on an object that is an indication of the system time at some critical point in the history of the object. 3. n. In query, the identification of the day and time when a query report was created that query automatically provides on each report.
timeout 1. n. An event that occurs at the end of a predetermined period of time that began at the occurrence of another specified event. 2. n. A time interval allotted for certain operations to occur; for example, response to polling or addressing before system operation is interrupted and must be restarted.

token-ring network 1. n. A ring network that allows unidirectional data transmission between data stations, by a token passing procedure, such that the transmitted data return to the transmitting station. 2. n. A network that uses a ring topology, in which tokens are passed in a circuit from node to node. A node that is ready to send can capture the token and insert data for transmission.
toolbox n. In graphical user interfaces (GUIs), a container that provides a graphical way of grouping tasks.
