task 1. Any major job performed by a computer. 2. One of several programs being executed by a system.

terminal Device equipped with a keyboard and connected to a computer or network.

testing 1. Process of running a program for the express purpose of discovering errors. 2. For computer±oriented systems, the process of verifying the ability of a system to meet performance objectives in a simulated environment, or validating its actual performance in a real±time environment.

text Portion of a message, program, or input that contains the information you want to convey.

text string Consecutive series of characters that are output exactly as specified in the command or program.

translation Function of a language processor that converts certain source programs, such as Basic, into a machine±readable language.

transmit To send data from one place to another.

truncate Cut off before completion, as when data transferred from a host

to a printer is cut off before all data is transmitted.

TSO Time Sharing Option. Host software that allows multiple terminals to communicate efficiently with a host. TSO command processors can edit data sets, submit jobs for batch execution, and perform data set manipulation.

typeface 1. Type of a single design. 2. Set of character with design features that make them similar to one another.
