What are the main differences between the power schemes standy and hibernate?
- A.
Hibernate boots back up faster than standby
- B.
You have to reboot to get out of hibernate and standby boots back up straight away.
- C.
Standby boots up faster than hibernate as in hibernate the applications are saved to a temporary file on the hard drive.
- D.
In hibernate the screen stays on, standby the screen goes off to save power.
Correct Answer
C. Standby boots up faster than hibernate as in hibernate the applications are saved to a temporary file on the hard drive.Explanation
When a computer is put into standby mode, it enters a low-power state where the screen turns off to save power. When the computer is woken up from standby, it can quickly resume where it left off, as the system state is saved in memory. On the other hand, hibernate mode saves the entire system state, including open applications and documents, to a temporary file on the hard drive. This allows the computer to completely shut down, consuming no power. When the computer is turned back on from hibernate, it takes longer to boot up as it needs to read the saved system state from the hard drive. Therefore, standby boots up faster than hibernate.Rate this question:
