I'm assuming we're talking about the National Basketball Association here. I could list the names of the NCAA conferences as well, but that would take a little longer than I want to spend. Also, the names of the Conferences is pretty easy: Eastern Conference and Western Conference. For the sake of completeness, I'm assuming that the question refers to the names of the Divisions within those Conferences.
