and keyboard drivers are installed for
Windows.
Revising the Control Panel settings or run-
ning the Windows Setup program may
change options in the system.ini file. On
other occasions, you may need to change or
add options to the system.ini file manually
with a text editor, such as Notepad.
Abbreviation for Transmission Control
Protocol/Internet Protocol.
Some devices, especially disk drives, con-
tain a terminator to absorb and dissipate
excess current. When more than one
such device is connected in a series, you
may need to remove the terminator—or
change a jumper setting to disable it—un-
less it is the last device in the series.
However, some devices have terminators
that should never be removed or disabled.
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.
See video mode.
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.
See also conventional memory, HMA,
memory manager, and upper memory
area.
The 384 KB of RAM located between
640 KB and 1 MB. If the computer has an
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
memory 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.
A program used to manage system re-
sources—memory, disk drives, or
printers, for example. The diskcopy com-
mand for duplicating diskettes and the
himem.sys device driver for managing
