The components in Debian (main, contrib, non-free) serve to divide up
software according to licensing terms, separating "Debian" from "not Debian,
but distributed by Debian".  The components in Ubuntu sort packages
according to quality standards as well as licensing terms (and the licensing
guidelines are different), so the Debian names don't apply.  To use them
anyway would be much more confusing.

"Universe" is the universe of free software.  "Multiverse" further
encompasses the related, but distinct, universe of proprietary software.

"Restricted" means that your rights to the software are restricted, in
contrast to the core (main) component of Ubuntu.

This is a bit confusing because two types of groupings are used in a single
set.  A more accurate representation would be to add a dimension:

main/free (main)
main/restricted (restricted)
universe/free (universe)
universe/restricted (multiverse)

However, this would be quite a lot of trouble and it's not clear that the
benefit would justify the effort (which could be better spent improving
the distribution itself).
