Disk partitioning
Disk partitioning is the creation of separate divisions of a hard disk drive using partition editors. Once a disk is divided into several partitions, directories and files of different categories may be stored in different partitions. More partitions provide more control but too many may become cumbersome. The way space management, access permissions and directory searching are implemented depends upon the type of file system installed on a partition. Careful consideration of the size of the partition is necessary as the ability to change the size depends on the file system installed on the partition. Purposes for partitioning: This section describes partitions as used in MS-DOS, Microsoft Windows and Linux on PC compatible computer systems; for examples of partitioning schemes used in other operating systems, see Slice (disk) and BSD disklabel. A PC hard disk can contain up to four partitions. Each of them can be a primary partition and at most one can be an extended one.
