I'm just going on basic understanding myself, but I'll take a shot at
these.
1. Just a way at quick glance to organize your files. Imagine you just
downloaded a few 'rpm' packages, you open a terminal window and do 'ls'
to see what you've got; if they're all the same, it would be a little
more of a strain to find the files you're looking for. I don't think
there's any tricky formula behind it; in my directory, text files are
green, executable files are bright green, rpm's and tar.gz files (both
are archives - just different types) are red, and graphics files are
purple. The '@' symbol designates a symlink (shortcut) and the '*' is
another way to indicate an executable.
2. I don't really know the 'exact' differences between the security
levels; maybe experiment? You've basically answered that one already
though. I would generally say though, that not all distros use the same
terms for the same environment; i.e.; what would seem to be 'medium'
security in Mandrake may very well be 'high' security in SuSE. I
believe that's just a matter of personal preference, and you've already
seen the results. I've loaded both SuSE and Mandrake / Red Hat distros
and have seen that when trying to use the minicom program (similar to
hyperterm in windows), I have to change permissions on the Mandrake /
Red Hat version but on the SuSE version, the $user is able to use it
right out of the box.
Hope that helps, Mike
