This is explained at the very beginning of the "Files" node in the Emacs 
manual.  The Glossary also explains that under Saving and under Visiting.  
These are very basic notions in Emacs, so if the relations between a buffer 
visiting a file and what happens when you save that buffer aren't clear to you, 
I suggest a good reading of those parts in the manual.
