SVGA (super video graphics array) A
video display standard that offers greater
resolution and color depth than VGA. The
resolution (clarity and sharpness) of an
image is determined by the number of
pixels that can be displayed per square
inch. Color depth is determined by the
number of colors (from 256 to 16 million)
that can be displayed simultaneously. The
number of both pixels and colors is limited
by the amount of video memory on the
SVGA system. See pixel.

resources needed by the operating system,
such as fonts, icons, and default dialog
boxes.

track Every time you write to a CD, you
create at least one track, that is preceded by
a gap. Any session may contain one or

data and audio tracks.

USB port (universal serial bus port) A
connector for plugging in multiple,
ultra-high-speed peripherals. USB ports
are gradually replacing serial ports and
parallel ports and eliminating the need for
so many connectors and cables. (Multiple
USB peripherals can be linked together in
a daisy chain to share the same port.)
Windows 98 included a built-in driver for
USB peripherals. Windows Millennium
supports a new USB standard that is 40
times faster than the previous standard. See
serial port and parallel port. See also
peripheral and driver.
Usenet (users’ network) A world-wide
network of computers set up to transmit
messages to newsgroups. See newsgroups.

utilities.
V
V.90 standard A standard adopted in
1998 to resolve two competing
technologies for 56Kbps modems. (If your
modem does not conform to the V.90
standard, you can visit the manufacturer’s
Web site and download a software update.)
