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:
“It is no small mischief to a boy, that many of the best years of his life should be devoted to the learning of what can never be of any real use to any human being. His mind is necessarily rendered frivolous and superficial by the long habit of attaching importance to words instead of things; to sound instead of sense.”
—William Cobbett (1762–1835)
“The mode of founding a college is, commonly, to get up a subscription of dollars and cents, and then, following blindly the principles of a division of labor to its extreme,—a principle which should never be followed but with circumspection,—to call in a contractor who makes this a subject of speculation,... and for these oversights successive generations have to pay.”
—Henry David Thoreau (1817–1862)
