FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Disk fragmentation causes files on your computer to be scattered on different parts of the disk. This usually happens when you install some application or delete a large number of files. When the files are stored in a contiguous space on the hard disk, the system must do extra work to retrieve files from the disk.

Detailed explanation-2: -Fragmentation makes your hard disk do extra work that can slow down your computer. Removable storage devices such as USB flash drives can also become fragmented. Disk Defragmenter in Windows rearranges fragmented data so your disks and drives can work more efficiently.

Detailed explanation-3: -Does defragging delete files? Defragging does not delete files. Some software programs, especially those made and sold by third-party companies, may include defragging as part of an overall maintenance program, and this program may include deleting temporary files or duplicate files.

Detailed explanation-4: -Defragmentation reverses the process your computer uses to break up data when it saves files to your hard drive. Defragging reformats your drive, reconstituting the files that were fragmented when they were written (saved) to your disk.
