Program instructions and data are spread across tracks and sectors on the hard disk drive
|
|
|
Programs and instructions are grouped together to occupy a continuous section of the harddisk drive
|
|
|
A hard disk drive that has been dropped and broken into lots of pieces

|
|
The hard disk drive is split into portions each representing a different logical drive.

Detailed explanation-1: -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-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: -Hence, a disk defragmenter is to Rearrange blocks of data to store files in contiguous sectors.
Detailed explanation-4: -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).
