Partitioning X86 Machines

There can be a maximum of four primary partitions or three primary partitions and one
extended partition (an extended partition can hold 15 (SCSI) or 63 (IDE) logical partitions).
Each partition is assigned a partition type, depending on the file system planned for the
partition.
Each partition holds its own file system.
Partitions are mounted into the file system tree at mount points. The content of the partition is
visible to users with sufficient access privileges below the mount point.
One of the partitions must hold the root (
the root file system by using the mount command).
The file holds partition and mount point information to allow automatic mounting
