A hard drive. Physically it is a single unit (but may have more than one surface or platter to store data). The drive has a 'reference' track - which tells the computer how the drive is divided. You can split a hard-drive into multiple partitions to separate different types of data.
Primary Partitions are logical areas on Coputer storage devices that have direct reference in Master Boot Record. (Due to limitation imposed by MBR only four primary partitions can be created). While Extended partitions refer to logical areas created out of need for more than four Partitions.
primary partitions, extended partitions, and logical drives.
On MBR partitioned hard-drives only 4 primary partition can be created. (Use extended and logical partitions to create more partitions).
4 ----- Dhyan Tripathi You can have 4 primary partitions, or 3 primary partitions and one extended partition containing any number of logical partitions. While you can assign a drive letter to a partition, you can also map it as

Typically you can only have 4 primary partitions per hard drive if you are using the MBR partition layout scheme. If you need more partitions than the maximum allowed (4), then there is a way to get many more partitions with only one hard drive.By creating an extended partition you can have as many logical partitions as you need within that extended partition, thus you can have more than only four partitions. You can have 3 primary partitions and one extended partition (for a total of 4), and inside the extended partition you can have as many logical partitions as you need.The one thing to keep in mind is that any type of Windows Operating System needs to be installed in a primary partition, otherwise you cannot boot into it. Windows XP in particular, needs to be installed in the first primary partition. For everything else, you can create as many logical partitions as you want inside the extended partition.
A basic disk contains 3 logical partitions, but only one of them can be the primary partition. This is only if the system has enough free space.
Ther can only be one Extended Partition per hard drive
Partition information: detailing the size and type of each partition on the hard drive. File system type: specifying the format used to organize and store data on the partitions. Boot information: indicating which partition contains the boot loader and bootable operating system.
there are two types of partitions in the hard disk is primary and logical.
Basic
Hard drive partitions that are accessed directly by the operating system are typically referred to as "primary partitions." These partitions can contain a file system and are directly addressable by the OS, allowing it to read and write data. In contrast, logical partitions, which reside within an extended partition, are accessed through the primary partition.
