What is the difference between iterative model and prototype

Iterative Model: In this u can come back to previous
phases, and make the changes accordingly. In this we
revived a final output product at the end of the SDLC.

Prototype Model: Here, we received Prototypes of the
product, before the final release. We release 4-5 Prototypes
with some differences b/w them, and take client opinion, and
modifies the final Product, as per client suggestions.
