Disk partition

 Disk partition:

                                             The process of  partitioning a hard drive is used to divide the physical capacity of a hard drive into separate logical area known as partitions or volume. The  partitions work  as independent hard drive and also known as logical drive. each partition is labeled and treated separately such as C drive and D drive although they are physically one drive.

                 One or more partitions are created  when a hard drive is first formatted. For example, many personal computers come with two partitions. the C drive partition is used for programs and data and D drive  partitions set up as recovery partition. A recovery partition  contains the data to  restore a hard drive back to its initial state in case the system  crash . 

                     In the past , operating system could only  use hard drive up to512 MB. The hard drive larger than 512 MB were divided into multiple  partitions. However, the partitioning  of a large hard drive increase efficiency . This is because operating system typically use a large cluster size with z large hard drive, it uses one  entire cluster of storage space to store even a small file. The disk space is often wasted when a large cluster size is used . The partitioning  allows each  logical drive to use a smaller cluster size that  save disk space.

             The partitioning must be done very carefully as deleting a partition erases all the data on that partition. Multiple partition can be used to install two different operating system on the same hard drive such as windows and Linux Storing data files on a separate partition makes it easier to search them.

                Types of Partition

                                      Different types of partition is as follows:

                 Primary partition;

                   

                                              The primary partition is a types of partition that can be used as system partition . The system partition contains the hardware-specific flies required to load Windows.

                 Extended partition:

                                                  The Expended partition is a types of partition that can be divided into sub partition. The sub partition are known as logical partitions. It is done for using multiple  operating system. A hard disk can have only one extended partition.
