One power state will close applications and files, and log off users like a full shutdown wood, then save the kernel State and system to a hibernation file before shutdown. Then, when the computer is restarted, it will automatically and quickly restore that file, saving some of the time involved in a normal boot. Which of the following states is being described?
A) hibernate
B) sleep
C) selective suspend
D) fast startup
Fast startup
Fast startup is similar to hibernate and how it works, but instead of saving all your applications and data as you had them so that you’re instantly back at work, it saves this system state. As described in the question, fast startup will close running apps and log off any users, then save the contents of RAM to a hibernation file. When the computer starts back up, it reads the hibernation file and loads drivers, system state, and the colonel much more quickly than it would if the system had to read all of that individually back into RAM as it normally would in a cold boot. Sleep stores everything that is open and RAM and enters a low power state. The display and drivers aren’t using power but power is needed to continually refresh memory so that it can retain the information. Sleep uses very little power but wakes up very quickly with everything open as it was. The hibernate option stores open programs and data to the hard drive and, once the computer is hibernated, would use no power, but it will not resume its state as quickly as sleep would
