Does an slr camera make way more high quality pics than a regular camera?

like, do they make more hd pics than a regular camera or what? because im into photography and i want to be able to get crisp clear hd looking pictures like you see in photography books or magazines. ok, maybe not that amazing looking because im pretty sure you need to lug around a bunch of lenses and lighting for that kind of stuff, but i want to get pictures that look way more nicer, crisp, and more clear than a regular digital point and shoot. so what exactly are the advantages of an slr vs point and shoot?
