You probably don't want to go there, if you are newbie, but largely because you won't understand at least half of it. Its not too
dangerous if you regard it as read-only
(never, ever write to it or change anything there) but there isn't any point in going there for anything that you are likely to want to do.
You almost always will find some tool that gives you information that you can understand (you may be able to understand, after you have read and re-read the man page), so you should start from there.
'man fstab' is a good place to start.
