Dumb question alert !

I can't figure out the difference between multiclassing and dual classing. I read the descriptions in various places but I just don't get it.

Seems to me that either one will let you work with the skills of more than one class, except that dual classing has a bunch of restrictions.

At the risk of sounding like an utter newbie, what is there difference here, and what are the advantages of one over the other?

As a beginner, would it be simpler to just start with a fighter and go for it? In some places a fighter/thief is recommended, but don't you find a thief along the way? I've not played a game where NPC's are added later, instead of making up your own party entirely.
