System shutdown is the process of halting system activity in an orderly
manner and stopping the computer operating system. A system shut
does not involve turning off power to the computer hardware.
If done properly, a shutdown preserves all system and user files and
copying any spool files that await printing to tape. Before the shutdown occurs, backlogged reports can be printed, or they can be saved to tape and replaced when the system is running again.
