Why can't the computer just be switched off?

Before the computer dies it prepares the information for its next life so it starts where it leaves, in order to do this the computer looks at itself and records it's present situation, that way next time it's switched on it doesn't have to learn about its environment.

What happens when the computer is switched on?

The start up process
Bios tells the processor where to load up the operating system
