Partition Table

The term partition table is most commonly associated with the MBR partition table of a Master Boot Record (MBR) in IBM PC compatibles, but it may be used generically to refer to other "formats" that divide a disk drive into partitions, such as: GUID Partition Table (GPT), Apple partition map (APM), or BSD disklabel.

An alternative term to generically refer to partition table is partition map.

Famous quotes containing the word table:

    The salt person and blasted place
    I furnish with the meat of a fable;
    If the dead starve, their stomachs turn to tumble
    An upright man in the antipodes
    Or spray-based and rock-chested sea:
    Over the past table I repeat this present grace.
    Dylan Thomas (1914–1953)
