What is the difference between Hibernate, Stand-By and Turn off?

In general, we know that there are several shut down options exist, for instance, Hibernate, Restart, Hibernate and Stand-by. The question is do you know exactly the difference between each of them? Have you ever wonder what is the difference between Hibernate and Stand-by in your laptop?

In short, the Turn Off command removes power from the computer, whereas Hibernate saves all documents in the memory and then turns off the computer. As for Stand-By, it places the entire computer in a low-power state but does not turn it off. Another word, with Hibernate and Stand-by, the next time you resume work on the computer, the computer is restored to exactly like how you left it!

As for Restart command, it is a warm boot. Booting is a process of starting or restarting a computer. There are two types of booting- warm boot and cold boot. Cold boot is when you turn on a computer than has been powered off completely whereas warm boot is the process of restarting a computer that already is powered on.
