Disk Partitioning
Disk partitioning is the creation of one or more regions on a hard disk or other secondary storage, so that an operating system can manage information in each region separately.[1] Partitioning is typically the first step of preparing a newly manufactured disk, before any files or directories have been created. The disk stores the information about the partitions locations and sizes in an area known as the partition table that the operating system reads before any other part of the disk.
