Tracks
Addressable, concentric circles on a disk, resembling the
grooves on a record, which help to divide the disk into separate
accessible areas. There are 80 tracks on each side of a double-
sided 1.2MB, 1.44MB, or 720KB diskette and 40 tracks on each
side of a double-sided 360KB diskette. The number of tracks on
a
hard disk depends on its capacity.
VGA
Video Graphics Array. A type of high-resolution color display
adapter. The VGA adapter built into the system board of your
computer can display 16-color graphics at a resolution of up to
800 x 600 on a multi-frequency monitor or up to 640
x
480 on
a standard VGA monitor.
Video card
A display adapter card that can be installed in one of the
computer’s option slots to provide a monitor interface. Your
computer comes with a built-in
VGA
adapter, so you do not
need to install a video card in your system if you are going to use
this interface.

Write-protect

a write-protect tab over the notch on the side of a 5

change, or record over its contents.
