surge protector

A device that protects a

computer from fluctuations in power. A
surge protector regulates the flow of
electricity to the computer and prevents
high-voltage surges from damaging
the equipment.

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 also pixel.

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 so many cables.
(Multiple USB peripherals can be linked
together in a 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
also serial port and parallel port.
See also peripheral.

A world-wide

network of computers set up to transmit

a software upgrade.)
