That's actually a pretty good question. Very simply, the root user is the
user who can do *anything* on a Linux computer, sort of like the
administrative user on a Windows computer. It can be quite dangerous to log
in as a root user unless you know what you're doing, because with the root
user it's possible to destroy an entire operating system with a single
command (and I've done it -- and by some miracle I managed to keep that job
anyway). Any actions that could change the system's configuration are done
by the root user, including mounting new filesystems, installing most
software, and so on.
For normal, every day use, you will almost never need to log in as root. The
way Kubuntu does things, with the sudo model, is more than adequate.
If you're still learning how Linux works, I suggest that you stick with your
current user account and not worry about the root user account for now.
Chances are you won't need it (I've been using Linux as my OS at home for six
years now, and I hardly ever need to log in as root; my regular user account
is adequate for 95% of what I do).
