What is the difference in baking with microwave oven and a typical oven?

Well, I am totally confused about baking stuff in ovens. The ones I usually see on TV and read on recipes about baking is that it should be put in the"OVEN"for about blahblahblah minutes.I don't know if it would be okay to use our microwave oven since we don't have the big oven at home. If it is possible, please give me the difference if I bake stuff in the microwave than just using the big oven. Thanks. ------
