A partition table is a table, maintained on a disk by the operating system, which outlines the partitions present on that disk. The terms "partition table" and "partition map" are often used in reference to the Master Boot Record's MBR (Master Boot Record) partition table. It also encompasses other formats that divide a disk into partitions, such as GPT (GUID Partition Table), APM (Apple Partition Map), and BSD disklabel. - _From_ Wikipedia

With a partition table, the computer can recognize the existing hard drive, and users can create, resize, or delete partitions on the disk. This table is typically created when installing an operating system on Windows and Mac computers.
