your computer cannot come out of hibernation

On the other hand, a system in sleep mode still consumes power to keep the data in the RAM.

A system in sleep mode only needs to power up the CPU and display, which is almost instantaneous. A hibernated system must start up and read data from permanent storage and then transfer that back to RAM, which takes longer and depends on the speed of the permanent storage device, often much slower than RAM memory. Instantaneous resumption is one of the advantages of sleep mode over hibernation. Many systems support a low-power sleep mode in which the processing functions of the machine are lowered, using a trickle of power to preserve the contents of RAM and support waking up. Apple hardware using macOS calls hibernation Safe Sleep. Google and Apple mobile hardware ( Android, Chromebooks, iOS) do not support hibernation. Most desktops also support hibernation, mainly as a general energy saving measure and allows for replacement of a removable battery quickly. It can be set to happen automatically on a low battery alarm. Hibernation is mostly used in laptops, which have limited battery power available. The system can have a total loss of power for an indefinite length of time and then resume to the original state. After hibernating, the hardware is powered down like a regular shutdown.
