Question

The disk clean-up program and disk defragmenter must be run once a __________.​

Answer 1

Answer:

Explanation:

Windows XP Professional saves files and folders in the first available space on a hard disk and not necessarily in an area of contiguous space. The parts of the files and folders are scattered over the hard disk rather than being in a contiguous area. This scattering of files and folders across a hard disk is known as fragmentation. When your hard disk contains numerous fragmented files and folders, your computer takes longer to access them because it requires several additional reads to collect the various pieces. Creating new files and folders also takes longer because the available free space on the hard disk is scattered. Your computer must save a new file or folder in various locations on the hard disk.

Temporary files, Internet cache files, and unnecessary programs also take up space on your computer's hard drive. Sometimes there are file system errors and sometimes sectors on your hard disk go bad, which can cause you to lose data you have stored on your hard disk. This lesson introduces three Windows XP Professional tools-Disk Defragmenter, Check Disk, and Disk Cleanup-that help you organize your hard disks, recover readable information from damaged areas on your hard disk, and clean up any temporary files and unnecessary programs taking up space on your hard drive.
