No, not at all. It can be either. Space can be wrapped up such that it is finite but with no boundary - in the way that the surface of the earth has no boundary but is finite.
To all who read this and get the idea that the universe is a sphere, don't. It very well may be, but that isn't what cavediver was eluding to(I think).
Keep in mind also that since the so-called 'edges' of the observable universe are 14pc away, this doesn't mean that the universe itself is only 14pc in radius. This can easily be thought of with a completely opaque balloon. If you take the balloon before it is inflated and fill it with a multitude of gases, these gases with start to react(possibly) and you could see a multitude of effects going on, if you were inside the balloon. Now if you fill the room you are in with the same gases the same reactions could happen, but you're inside the balloon, so you can't see them.
