Which of the following are the advantages of Standby mode over Hibernate mode?
Each correct answer represents a complete solution. Choose two.
A.
Shorter wake-up period
B.
Lower power consumption
C.
Longer wake-up period
D.
No consumption of hard disk space
Explanation:
Standby mode has a shorter wake-up period than Hibernate mode. Unlike Hibernate mode, in
Standby mode, the contents of the computer’s main memory are not saved to the hard disk, and the
operating system need not read contents from the hard disk each time the computer is restarted.
Therefore, Standby mode takes lesser amount of time to wake-up as compared to Hibernate mode.
Moreover, a computer in Standby mode does not consume any hard disk space.
FactWhat is hibernate mode? Hide
Hibernate mode is a power saving feature for computers. In hibernate mode, the current state of a
computer is saved to the hard disk, and the computer shuts down. A user will have to power on the
computer to restore the previous settings. When a computer resumes from hibernate mode, it reads
the saved settings from the disk and restores the system state as it was before it entered hibernate
mode. By default, hibernate mode is disabled. If a computer is not ACPI-enabled or APM-enabled,
users will have to enter hibernate mode manually. Users cannot set the computer to automatically
hibernate after a certain time. With ACPI-enabled and APM-enabled computers, users are able to set
hibernate mode automatically.
Answer option B is incorrect. Since Standby mode maintains the current state of the computer in the
computer’s RAM, it consumes a small amount of power, whereas Hibernate mode writes contents to
the hard disk and shuts down the computer completely. As a result, a computer in Hibernate mode
requires no power to maintain the current state.Reference: TechNet, Contents: “Chapter 20 – Power Management”
