GLOSSARY

terminal		Device equipped with a keyboard and connected to a computer
		or a network.
testing		1. Process of running a program for the express purpose of
		discovering any errors it may contain. 2. For computer-oriented
		systems, the process of verifying a system©s ability to meet
		performance objectives in a simulated environment or validating
		its actual performance in a live environment.
	text	In communications, the content portion of a transmitted
		message.
text	string	Consecutive series of characters to be printed exactly as
		specified in a command.
throughput		In data processing systems, the amount of data that can be
		processed, transmitted, printed, and so on, per a specified unit
		of time.
	toggle	To switch (alternate) from one tray to another. The system will
		switch from an active feeder or stacker tray to an inactive one to
		allow continuous printing when the proper commands are
		invoked.
	token	Coded character representing a word used in programs, for
		example, STOP is a word and the one-byte token for it in a
		BASIC dialect is 250.
	track	Unit of storage space on a data storage medium, such as a disk.
		All information stored in a track can be retrieved or recorded in
		one positioning of a read/write head.
	trailer	In data communications, the last portion of a message that
		signals the end.
transaction processing		Method of data processing in which files are updated and results
		are generated immediately after data entry.
translation		1. In data communications, the conversion of one code to
		another on a character-by-character basis. 2. In programming,
		the function of a language processor which converts a source
		program from one programming language to another.
transmission	speed	In data communications, the rate at which data is passed through
		communication lines, usually measured in bits per inch (bpi).
transmit		To send data from one place to another.
truncated		Cut off before completion, as when data transfer from a host to
		a printer is cut off before all data has been transmitted.
