How is the computer able to save things before it crashes?
Problem
I was under the impression that when a computer has crashed, something went wrong and it can't perform anymore. I was wondering how is the computer able to save things before it crashes? Is the computer really capable of knowing when it's going to crash (and thus inform all processes: "Save ASAP because I'm about to crash") ? If not, how is it possible that programs like and can offer "restoring" services after the computer has crashed?

Chrome and Microsoft Word periodically save your current state as you're working. If the application or computer crashes, when the applications relaunch, they look for a saved state on disk, and restore it for you. They don't need to predict the crash; they are constantly saving your state in case something goes wrong.
