Long Mode

In the x86-64 computer architecture, long mode is the mode where a 64-bit application (or operating system) can access 64-bit instructions and registers. 32-bit programs and 16-bit protected mode programs are executed in a compatibility sub-mode; real mode or virtual 8086 mode programs cannot run in this mode.

Famous quotes containing the words long and/or mode:

    “Your strength, that is so lofty and fierce and kind,
    It might call up a new age, calling to mind
    The queens that were imagined long ago,
    Is but half yours....”
    William Butler Yeats (1865–1939)

    Sight is the least sensual of all the senses. And we strain ourselves to see, see, see—everything, everything through the eye, in one mode of objective curiosity.
    —D.H. (David Herbert)
