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.

Abbreviation for thin film transistor. A flat-
panel display for notebook computers
where each pixel is controlled by one to
four transistors.
Abbreviation for tracks per inch.
Abbreviation for terminate-and-stay-
resident. A TSR program runs "in the
background." Most TSR programs imple-
ment a predefined key combination
(sometimes referred to as a "hot key")
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.
Abbreviation for television.
Abbreviation for Underwriters
Laboratories.
Abbreviation for upper memory blocks.

Intel386 or higher microprocessor, a soft-
ware utility called a memory manager can
create UMBs in the upper memory area, in
which you can load device drivers and
memory-resident programs. See also
conventional memory, HMA, and memo-
ry manager.
Abbreviation for uninterruptible power
supply. A battery-powered unit that
automatically supplies power to your
computer in the event of an electrical
failure.
Abbreviation for Universal Service Order-
ing Code.

tended memory are utilities included in
MS-DOS.
