When you export Audio and Video, what do the different "passes" mean?

I notice that when I render both audio and video, it goes through different stages which include a number of "passes" when rendering the video. What does this mean?

    For video multi-pass mode results in a better quality render.  You can also choose single pass for a faster but poorer quality encode.  This is universal for any Quicktime render.

    For audio rendering, the Normalize and Render as Loop options both require a preview pass to analyze the audio (find peak / compute the tail) before rendering. I don't know if there are video options that also require preview passes.
