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.

“It is very important not to become hard. The artist must always have one skin too few in comparison to other people, so you feel the slightest wind.”

“We teach boys to be such men as we are. We do not teach them to aspire to be all they can. We do not give them a training as if we believed in their noble nature. We scarce educate their bodies. We do not train the eye and the hand. We exercise their understandings to the apprehension and comparison of some facts, to a skill in numbers, in words; we aim to make accountants, attorneys, engineers; but not to make able, earnest, great- hearted men.”
—Ralph Waldo Emerson (1803–1882)
“When I sleep I sleep and do not dream because it is as well
that I am what I seem when I am in my bed and
dream.”
—Gertrude Stein (1874–1946)
“Literature exists at the same time in the modes of error and truth; it both betrays and obeys its own mode of being.”
—Paul Deman (1919–1983)
