FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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-2: -Disks become fragmented over a period of time after continuous usage. Disk defragmentation helps rearrange the files on the disk to contiguous spaces and thus improve disk performance.

Detailed explanation-3: -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-4: -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.
