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: -Disk fragmentation occurs when a file is broken up into pieces to fit on the disk. Because files are constantly being written, deleted and resized, fragmentation is a natural occurrence. When a file is spread out over several locations, it takes longer to read and write resulting in slow computer performance.
Detailed explanation-3: -Defragmentation is the process of locating the noncontiguous fragments of data into which a computer file may be divided as it is stored on a hard disk, and rearranging the fragments and restoring them into fewer fragments or into the whole file.
Detailed explanation-4: -Those fragmented, individual pieces of data are referred to generally as fragments. Defragmentation, then, is the process of un-fragmenting or piecing together, those fragmented files so they sit closer, physically, on the drive or other media, potentially speeding up the drive’s ability to access the file.
