Ok I appreciate trying to lead me to the technical stuff -- but just because I
want to learn how to drive doesn't mean I want to learn how to take a car apart
and put it back together again.

In other words, I just want to know how to operate the Ubuntu Linux safely not
how to program it. I would be happy with going from Beginning to Intermediate
as I learn without even worry about the Advance part of it.

Again the Question is:

How do I know if I am a Root User or just a regular Administrator? I don't want
to be in the Root User but at the same time I do want to add programs from the
Software Center and Update the Software from the Updater program which I have
been doing. I don't understand the article they are very technical. I simply
want to avoid being in the Root User format that causes the security problems in
Ubuntu Linux. Now is the Root User something that is done in the terminal only?
