System diskette

A diskette that contains the operating system.

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 display adapter. The VGA adapter built into the system board of your computer can display 16-color graphics at resolutions up to 1024 x 768 or 256-color graphics at resolutions up to 640 x 480.

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

To store data on a disk.

Write-protect

To protect the data on a diskette from being changed by placing a write-protect tab over the notch on the side of a 5¼-inch diskette or by setting the write-protect switch on a 3½-inch diskette. When a diskette is write-protected, you cannot erase, change, or record over its contents.
