Glossary 167
TFTP

FTP protocol that has no directory or password capability.
text mode
A video mode that can be defined as x columns by y rows of characters.
threshold values
Systems are normally equipped with various sensors that monitor temperature,
voltage, current, and fan speed. The sensor's threshold values specify the ranges
(min and max values) for determining whether the sensor is operating under
normal, noncritical, critical or fatal conditions. Server Administrator-supported
threshold values are
• UpperThresholdFatal
• UpperThresholdCritical
• UpperThresholdNon-critical
•Normal
• LowerThresholdNon-critical
• LowerThresholdCritical
• LowerThresholdFatal
time-out
A specified period of system inactivity that must occur before an energy
conservation feature is activated.
tpi
Abbreviation for tracks per inch.
TQFP
Abbreviation for thin quad flat pack.
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.
