Today modern PC comprises total capacity of nearly 40GB for storage of program and data Due to this huge capacity in place of having just one operating system in our PC partitions are used to offer many separate areas within one disk each one treated as a separate storage device. Which means a disk partition is a sub-division of the disk in one or more areas. Every partition can be used to hold a different OS.

Low level formatting is placing track and sector information in addition of bad block tables and other timing information on disks. Sector interleave can be specified too at this time.
