Glossary
TCP/IP
— Transmission Control Protocol/Internet Protocol.
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.
TOE
— TCP/IP offload engine.
U-DIMM
— An unregistered (unbuffered) DDR3 memory module.
uplink port
— A port on a network hub or switch used to connect to other hubs or
switches without requiring a crossover cable.
UPS
— Uninterruptible power supply. A battery-powered unit that automatically
supplies power to your system in the event of an electrical failure.
USB
— Universal Serial Bus. A USB connector provides a single connection point for
multiple USB-compliant devices, such as mice and keyboards. USB devices can be
connected and disconnected while the system is running.
USB memory key
— See
memory key
.
utility
— A program used to manage system resources—memory, disk drives,
or printers, for example.
V
— Volt(s).
VAC
— Volt(s) alternating current.
VDC
— Volt(s) direct current.
VGA
— Video graphics array. VGA and SVGA are video standards for video adapters
with greater resolution and color display capabilities than previous standards.
video adapter
— The logical circuitry that provides (in combination with the monitor)
your system’s video capabilities. A video adapter may be integrated into the system
board or may be an expansion card that plugs into an expansion slot.
video memory
— Most VGA and SVGA video adapters include memory chips in
addition to your system’s RAM. The amount of video memory installed primarily
influences the number of colors that a program can display (with the appropriate video
drivers and monitor capabilities).
video resolution
— Video resolution (800 x 600, for example) is expressed as the
number of pixels across by the number of pixels up and down. To display a program
at a specific graphics resolution, you must install the appropriate video drivers and
your monitor must support the resolution.
