Putting a device into a low-power mode where only RAM is powered to conserve power at the expense of time to resume operation

Sleep is a mode where only the RAM is powered. Related topics include the waking, and hibernation where the contents of RAM are saved to storage and power is suspended from RAM as well. Apple combines sleep with hibernation under the marketing term "safe-sleep" where Macs will prepare for hibernation and then optionally enter it after a period of sleep to further preserve battery life.
