Pasteurization is a method of heating milk for example to a high heat (185 or more) in order to quickly kill *all* micro-organisms in it.
Fermentation for food (again for milk, but there are other kinds of fermentation) is a method for allowing certain "good" bacteria to grow so that they can begin eating the natural milk sugar (lactose) in milk and turn it into lactic acid (to make yogurt, etc).
