Glossary 207
time-out
A specified period of system inactivity that must occur before an energy
conservation feature is activated.
tpi
Abbreviation for tracks per inch.
TSR
Abbreviation for terminate-and-stay-resident. A TSR program runs "in the
background." Most TSR programs implement a predefined key combination
(sometimes referred to as a hot key) that allows you to activate the TSR program's
interface while running another 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. TSR programs can sometimes cause
memory conflicts. When troubleshooting, rule out the possibility of such a
conflict by rebooting your system without starting any TSR programs.
TSOP
Abbreviation for thin small outline package. A very thin, plastic, rectangular
surface mount chip package with gull-wing pins on its two short sides.
UDP
Abbreviation for user datagram protocol.
UMB
Abbreviation for upper memory blocks.
unicode
A fixed width, 16-bit world wide character encoding, developed and maintained
by the Unicode Consortium.
upper memory area
The 384 KB of RAM located between 640 KB and 1MB. If the system has an
Intel386 or higher microprocessor, a utility called a memory manager can create
UMBs in the upper memory area, in which you can load device drivers and
memory-resident programs.
URL
Abbreviation for Uniform Resource Locator (formerly Universal Resource
Locator).
