Final answer:
The sleep command does not shut down the computer; it saves open documents and maintains the session in a low-power state to save electricity and allow quick resumption of work.
Step-by-step explanation:
The statement is False. The 'sleep' command is a computer command that allows the computer to enter a low-power state while preserving the current session and open files. It is not the same as shutting down the computer, as the computer can be quickly awakened from sleep mode without losing any unsaved work. When the computer is shut down, it completely powers off and any unsaved work will be lost.
