Basically, you shut the computer down. Procedure for that depends on the specific operating system. Operating system is what makes a computer do things. Even the thing the loads the main operating system for a given computer is a small operating system in itself. For example, the thing that loads Windows or Linux up is called BIOS, and that stands for Basic Integrated Operating System. Once you exit all the operating system(s) you may as well shut down the machine (if it does not shut down by itself.)
The fsck command can be used to repair improperly shut down or potentially corrupt partitions on Linux systems. It checks the file system integrity and attempts to repair any inconsistencies it finds.
Well, I believe there's some sort of pump included in the nervous system. If that pump shut down, you'd die instantly, so you'd die instantly if the systems shut down. It's also highly unlikely that the digestive system would "shut down", as it begins in the mouth.
If you want to shut down the computer, usually "poweroff" or "shutdown -h now" would do. If you want to exit from the graphical interface, you typically just need to shut down the X server (the graphical session generally runs through a display manager session or your startx command)
Usually you don't shut them down at all. Actually if you want to shut it down - you have to tell it why your shutting it down - not sure if this applies to Linux servers. But if you ever try shutting down and starting up a server with just an active directory and exchange installed... you will soon realise the meaning of the word 'patience'.
Virtually all Linux distributions will accept the "halt" command. Some also have a shutdown command, though this has additional parameters and is meant mainly to shut down the system at a certain time.
if the pancreas dies the digestive system in general should be shut down.
