WH[W±HGLWRU
An application program for editing text
files consisting exclusively of ASCII
characters. MS-DOS Editor and Notepad
(in Windows) are text editors, for exam-
ple. Most word processors use
proprietary file formats containing binary
characters, although some can read and
write text files.
WH[W±PRGH

7)7
Abbreviation for thin film transistor. A flat-
panel display for notebook computers
where each pixel is controlled by one to
four transistors.
WSL
Abbreviation for tracks per inch.
765
Abbreviation for terminate-and-stay-
resident. A TSR program runs ²in the
background.³ Most TSR programs imple-
ment a predefined key combination
(sometimes referred to as a ²hot key³)
that allows you to activate the TSR pro-
gram±s interface while running another
MS-DOS program. When you finish using
the TSR program, you can return to the
other application program and leave the
TSR program resident in memory for later
use.
Because MS-DOS is not designed to
support multiple programs running simul-
taneously, TSR programs can sometimes
cause memory conflicts. When trouble-
shooting, rule out the possibility of such a
conflict by rebooting your computer with-
out starting any TSR programs.
79
Abbreviation for television.
8/
Abbreviation for Underwriters
Laboratories.
80%
Abbreviation for upper memory blocks.
