STANDBY MODE HAS A SHORTER WAKE-UP PERIOD THAN HIBERNATION MODE

4.

Correct Answers: A and E

A. Correct:

Standby mode has a shorter wake-up period than hibernation mode.

Waking from hibernation requires reading the contents of the system’s memory

from the hard disk.

B. Incorrect:

A mobile computer running Windows XP Professional might wake up

from standby mode to execute a scheduled task or switch to hibernation mode.

This possibility restricts this mode from being used during the takeoff or landing

of a commercial airplane.

C. Incorrect:

Standby mode minimizes battery usage by shutting down as many

components as possible. However, it maintains the state of the computer in the

system’s RAM, which requires small amounts of power. Hibernation writes the

contents of the system’s RAM to the hard disk and shuts the system down com-

pletely. Therefore, hibernation has a lower power consumption than standby

mode.

D. Incorrect:

Standby mode maintains the state of the computer in the system’s

RAM, which requires small amounts of power. If power is lost suddenly, for exam-

ple if the battery is removed, data is lost. Hibernation does not have this limitation

because no power is required to maintain that state.

E. Correct:

Standby mode maintains the state of the computer in system’s RAM—

only hibernation mode writes the system’s memory to the hard drive. As a result,

you must have enough free disk space to store the contents of the system’s mem-

ory to use hibernation mode.
