A disk is a data storage medium consisting of a flat, circular, magnetic surface on which information can be recorded. You will receive several disks with your computer. These already contain information and programs, and are ready to use.
Blank disks can be used to store your own information and programs, but these disks must be formatted before they can be used.
Disks which contain important information can be write-protected. This means you can read from but not write to the disk, making it impossible to write accidentally over information. Your disks can be write-protected - instructions are included in each box of disks.
