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:
“The city is recruited from the country. In the year 1805, it is said, every legitimate monarch in Europe was imbecile. The city would have died out, rotted, and exploded, long ago, but that it was reinforced from the fields. It is only country which came to town day before yesterday, that is city and court today.”
—Ralph Waldo Emerson (1803–1882)
“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)
