termination
Some devices (such as the last device at each end of a SCSI cable) must be terminated to prevent reflections and spurious signals in the cable. When such devices are
connected in a series, you may need to enable or disable the termination on these devices by changing jumper or switch settings on the devices or by changing settings in
the configuration software for the devices.
text editor
An application program such as Windows Notepad that is used for editing text files. Most word processors use proprietary file formats containing binary characters, although
some can read and write text files.
text mode
A video mode that can be defined as x columns by y rows of characters.
TFT
Abbreviation for thin-film transistor. From one to four of these transistors control each pixel in an active-matrix display for portable computers.
time-out
A time-out is a system setup option that activates a power conservation feature after a specified period of inactivity.
tpi
Abbreviation for tracks per inch.
trackball
A pointing device built into a portable computer that controls the movement of the cursor on the screen. Trackball-aware software allows you to activate commands by rolling
the trackball and clicking its buttons while pointing at objects displayed on the screen.
touch pad
A pointing device that detects the position of your finger over a touch-sensitive area. It is PS/2 compatible and provides full mouse functionality.
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.
Because MS-DOS is not designed to support multiple programs running simultaneously, TSR programs can sometimes cause memory conflicts. When troubleshooting, rule
out the possibility of such a conflict by rebooting your computer without starting any TSR programs.
UL
Abbreviation for Underwriters Laboratories.
UMB
Abbreviation for upper memory block.
upper memory area
The 384 KB of RAM located between 640 KB and 1 MB. 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.
UPS
Abbreviation for uninterruptible power supply. A battery-powered unit that automatically supplies power to your computer in the event of an electrical failure.
USB
Abbreviation for Universal Serial Bus. A USB port provides a single connection point for multiple USB-compliant devices such as mice, keyboards, printers, and computer
speakers. USB devices can be connected and disconnected while the system is running.
UXGA
Abbreviation for ultra extended graphics array.
