208 Glossary
USB
Abbreviation for Universal Serial Bus. A USB connector provides a single
connection point for multiple USB-compliant devices, such as mice, keyboards,
printers, and computer speakers. USB devices can also be connected and
disconnected while the system is running.
utility
A program used to manage system resources —memory, disk drives, or printers.
utility partition
A bootable partition on the hard drive that provides utilities and diagnostics for
your hardware and software. When activated, the partition boots and provides an
executable environment for the partition's utilities.
varbind
An algorithm used to assign an object identifier (OID). The varbind gives rules
for arriving at the decimal prefix that uniquely identifies an enterprise, as well as
the formula for specifying a unique identifier for the objects defined in that
enterprise's MIB.
variable
A component of a managed object. A temperature probe, for example, has a
variable to describe its capabilities, its health or status, and certain indexes that
you can use to help you in locating the right temperature probe.
VGA
Abbreviation for video graphics array. VGA and SVGA are video standards for
video adapters with greater resolution and color display capabilities than previous
standards. To display a program at a specific resolution, you must install the
appropriate video drivers and your monitor must support the resolution. Similarly,
the number of colors that a program can display depends on the capabilities of
the monitor, the video driver, and the amount of video memory installed for the
video adapter.
VGA feature connector
On some systems with a built-in VGA video adapter, a VGA feature connector
allows you to add an enhancement adapter, such as a video accelerator, to your
system. A VGA feature connector can also be called a VGA pass-through
connector.
