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 reaching and possibly 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 pixel.
system file
A resource file that contains resources needed by the operating
system, such as fonts, icons, and default dialog boxes.
T
taskbar
See Windows taskbar.
table of contents
Shows the number of tracks, their starting locations, and the total
length of the data area for a whole CD or any session within a CD.
The table of contents does not show the length of each track, only its
starting point.
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 more tracks, and
the tracks within a session may be of the same or of different types.
For example, a mixed-mode CD contains data and audio tracks.
