Comparison To Sleep Mode
Many systems also support a low-power sleep mode or stand by mode in which the processing functions of the machine are powered down, using a little power to preserve the contents of RAM and support waking up; wakeup is almost instantaneous.
The advantage of sleep mode is that resuming is much quicker than for hibernation. A hibernated system must start up, then read back data to RAM on resuming, which typically takes about ten seconds or more. A system in sleep mode only needs to power up the CPU and display, which is almost instantaneous. On the other hand, a system in sleep mode still consumes some power, while a hibernated system does not require any power at all. A sleeping computer is a case of a device consuming standby power, covered by regulations in many countries limiting such power under the One Watt Initiative to one watt from 2010. Since these facilities were introduced, most systems have come to offer both sleep mode and hibernation.

Famous quotes containing the words comparison, sleep and/or mode:
“In comparison to the French Revolution, the American Revolution has come to seem a parochial and rather dull event. This, despite the fact that the American Revolution was successful—realizing the purposes of the revolutionaries and establishing a durable political regime—while the French Revolution was a resounding failure, devouring its own children and leading to an imperial despotism, followed by an eventual restoration of the monarchy.”
—Irving Kristol (b. 1920)
“After I went to bed I had a curious fancy as to dreams. In sleep the doors of the mind are shut, and thoughts come jumping in at the windows. They tumble headlong, and therefore are so disorderly and strange. Sometimes they are stout and light on their feet, and then they are rational dreams.”
—James Boswell (1740–1795)
“The character of the logger’s admiration is betrayed by his very mode of expressing it.... He admires the log, the carcass or corpse, more than the tree.... What right have you to celebrate the virtues of the man you murdered?”
—Henry David Thoreau (1817–1862)
