Partition
Partition type
Main partition: When the first partition of the hard disk is usually designated as the primary partition. For example, in Windows, a hard drive only allows up to 1 primary partition. But you can create 4 primary partitions in Linux. Extended partition: You can create multiple logical partitions on the extension partition. In theory, there is no number of logical partitions. When the extension partition is created, it takes up a position of a primary partition. The extension partition is not used to store data directly, and its main function is to create a logical partition. Logical partitions: It must be attached to the extension partition and are restricted by the expansion partition size. Usually logical partitions are places where files and data are stored.

For example, when the first hard disk (/ DEV / HDA) divided by IDE1, one primary partition is created, and an extension partition is divided and 3 logical partitions are created. At this time, the name of each partition of this hard drive is shown below.
