152 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.
