About Partition Table
Generally, a partition is a fixed-size subset of a disk
drive which is considered as a section by the Windows operating system. A Partition
Table is a table maintained on disk by the operating system to describe the
partitions on that disk. The partition table is most associated with the Master Boot
Record (MBR). But it may refer to other partition styles, like GPT (GUID Partition
Table), and APM (Apple Partition Map), etc.
