well, Partitioning is the process of dividing the hard disk's space into chunks, so they can be prepared for use, or even dedicated to different uses. Even if the entire disk is intended to be left in one piece, it must be partitioned so that the operating system knows that it is intended to be left in one piece.
Primary Partition - A partition that is used to start an operating system, although you can use primary partitions that don't contain the operating system. Look at the color coded key at the bottom of Fig. 01 and you'll see that Primary partitions are denoted by the dark blue color.
* There can be up to a maximum of four primary partitions on a single basic disk.
* The Primary partitions do not have to come before Extended partitions as shown on Disk 0.
* A drive is not required to have any Primary partitions as shown by Disk 1
* CD-ROM 1, while it does contain a blank CD, is not shown as containing a partition because there is no data contained on the CD.
Extended Partition - A partition that can be sub-divided into logical drives. Look at the color coded key at the bottom of Fig. 01 and you'll see that Extended partitions are denoted by the dark green color.
* An extended partition is not formatted or assigned a drive letter.
* It's essentially a container for logical drives that are formatted and assigned drive letters. Disk 0 and 1 contain extended partitions that have a green band surrounding the logical drives (discussed below) that have been created in the extended partition.
