Parts of the file are scatters in different places on the hard disk

|
Parts of the file are stored sequentially on the hard disk

Detailed explanation-1: -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-2: -Disk fragmentation occurs when files or pieces of files get scattered throughout your disks. Not only do hard disks get fragmented, but removable storage can also become fragmented. This can cause poor disk performance and overall system degradation.
Detailed explanation-3: -In the maintenance of file systems, defragmentation is a process that reduces the degree of fragmentation. It does this by physically organizing the contents of the mass storage device used to store files into the smallest number of contiguous regions (fragments, extents).
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.
Detailed explanation-5: -Having a large number of highly fragmented files sitting on your hard drive not only reduces read and write performance, but it can also affect longevity of the hard drive itself.
