Page Table

A page table is the data structure used by a virtual memory system in a computer operating system to store the mapping between virtual addresses and physical addresses. Virtual addresses are those unique to the accessing process. Physical addresses are those unique to the hardware, i.e., RAM.

Famous quotes containing the words table and/or page:

    When the painted birds laugh in the shade,
    When our table with cherries and nuts is spread:
    Come live, and be merry, and join with me
    To sing the sweet chorus of ‘Ha, ha, he!’
    William Blake (1757–1827)

    A book is like a man—clever and dull, brave and cowardly, beautiful and ugly. For every flowering thought there will be a page like a wet and mangy mongrel, and for every looping flight a tap on the wing and a reminder that wax cannot hold the feathers firm too near the sun.
    John Steinbeck (1902–1968)
