What is the difference between waterfall model iterative waterfall model successive model prototyping model and spiral model?

I will try to answer this quickly as I don't have much time.

As the name suggests, the waterfall model follows the path of an waterfall. It starts in the first stage of orientation, and ends at the release. It can only go one way (to the end goal) and the stages are very strict (you cant go back to a earlier stage).

The Spiral model understands that reality doesn't always follow theory, and that an project should be designed to follow that reality. There are multiple prototypes released, and phases can be repeated until the desired result is reached (hence the spiral).

The iterative model combines those two, making (IMHO) the waterfall model more ready for the real world.

You should try googling yourself, I found lots of info about the differences in this article about the advantages of the waterfall model: http://www.waterfall-model.com/the-waterfall-model-avantages-and-disadvantages
