Explain Some Basic Concepts on Disk Partitioning
With the rapid development of economy and technology, now computers become as our companions. With them, we come into contact with more and more vocabularies but not easy to comprehend some basic concepts. In fact, your can ease to understand some basic computer HD knowledge on this article as some computer freshman bothered by the same questions. So have a look at this article mainly focuses on disk partitioning and the related vocabularies, it sure helps you.
Partition is known as the operations of segmentation the storage space of hard drive into separate data areas, including create, delete, move, format and resize partition or modify these partitions.

A master boot record (MBR), or partition sector, is the 512-byte boot sector that is the first sector ( the LBA value is 0) of a HD partitioned data storage device. The MBR do nor spread over a partition but the Main Boot Record area in front of the first partition, generally users is prevent to this area because this area belongs to firmware.

An extended partition is a new partition constitute with a lengthening partition from the primitive partition and the original partition. A hard disk may only contain one extended partition which can late be sub-divided into logical drives all assigned additional drive letters.
Take an example in DOS & Windows, the drive letters: C: typically assigns for the primary partition and one extended partition; D: and E: for the two latter logical drives.
To make a conclusion, you should understand of disk partitioning, MBR, primary partition and extended partition. Thanks your attention this article and hope it helpful to you.
