system board

As the main circuit board, the system board usually contains most of your computer's integral components, such as the following:

l

Microprocessor

l

RAM

l

Expansion-card connectors

l

Controllers for standard peripheral devices, such as the keyboard

l

Various ROM chips

Frequently used synonyms for system board are motherboard and logic board.

system diskette

A synonym for bootable diskette.

system memory

A synonym for RAM.

System Setup program

System Setup program options allow you to configure your computer's hardware. Some options in the System Setup program require that you
reboot the computer in order to make a hardware-configuration change. Because the System Setup program is stored in NVRAM, any options that
you set remain in effect until you change them again.

system.ini file

When you start Windows, it consults the system.ini file to determine a variety of options for the Windows operating environment. Among other
things, the system.ini file records which video, mouse, and keyboard drivers are installed for Windows.

Making changes through the Control Panel or 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.

T

terminator

Some devices, especially disk drives, contain 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—unless it is the last device in the series. However,

some devices have terminators that should never be removed or disabled.

text editor

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

TFT

Thin film transistor. A flat-panel display for notebook computers where each pixel is controlled by one to four transistors.

tpi

tracks per inch

TSR

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 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 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.
