No problem. /proc is sort of a psuedo file system that enables
some routines such as top to look at certain pieces of information.
Probably /net and /host are also psuedo file systems, but I have
never seen them before. If they are legit, they are for something
I do not run.

A mount point is just a directory where the system attaches pointers
to some type of data structure. You create a mountpoint using
the mkdir command just like with a directory. It only becomes a
mountpoint when something is attached to it - a file system or some
other system structure. Of course, actual file systems such as
for / or /usr or /home are the most common seen, others, including
memory file systems can be created and attached to a directory.
When a filesystem is mounted over a directory, if there is something
else in the directory - other files and directories - they are covered
up until the attached item is unmounted.
That all probably isn't very clear, but it should at least let you
not worry too much.
