A track is mostly the same as a bus. Only one (big) difference: A track also 
records to and plays from the harddisk. This recording/playback point is right 
at the top (speaking in the mixer-channel), that is you audio is recorded as 
plain as possible and all effects / routing are applied afterwards.
A bus doesn't have this recording possibility, its more like a mixer-channel 
in the real world.

Connecting the output of a track to the input of a bus and that output to the 
input of the track again gives you a nice little feedback. And its a digital 
feedback, so no nice sinus-wave...

A bus is a multi-purpose thingie, you can use to to split your track into an 
unmodified and a modified version and by that mix (and automate) the original 
and for example the phasered version. You can also use it to act like a bus on 
mixing consoles and connect several tracks to one bus and then have one fader 
(and effect chain) for them all to go to the main-mix. But you can do all sorts 
of things with this.

Have fun,
