water fall Model:when the customer requirements are clear and complete.

Prototype Model:when the customer requirements are not clear  ambigeous or our project team is following this model with sample first.

Spiral Model:when the requirements  of the customer are enhausing.(Improving and Extending)

There is no such difference between these models, its depends up on the product or application.

Different companies uses different models. its it!

Appriciate for your help

Waterfall model is a rigid model and can easily be manageble but spiral model is notwaterfall model works well on smaller projects whereas spiral model woks on larger projects alsowaterfall model is a iterative process whereas spiral model is a partitioned in four quadrants it is also called meta model.

Waterfall Model : The waterfall model is a Sequential Software Development process in which progress is seen as flowing steadily downwards through the phases of Conception, Initiation, Analysis, Design, Construction, Testing and
Maintenance

Prototype Model: In Prototype Model, a Prototype is built to understand the requirements. This Prototype is developed based on the currently known requirements. Development of the Prototype obviously undergoes design, Coding and testing. But each of these phases is not done very formally or thoroughly. By using this prototype, the client can get an "actual feel" of the system, since the interactions with prototype can enable the client to better understand the requirements of the desired system.

The Spiral Model is a software development process combining which elements of both design and prototyping-in-stages, in an effort to combine advantages of top-down and bottom-up concepts. Also known as the Spiral lifecycle Model. This Model of development combines the features of the prototyping Modal and the Water fall Modal. The Spiral Modal is intended for large, expensive and complicated projects.

In water fall model, the customer requirements are very clear, so verification is enough, validation is not req. The water fall model and V-model are suitable for small type of projects.

In the V-model the customer req. are not clear so, both verification and validation is needed.

May I suggest wikipedia! You need to do a lot of reading.

Waterfall model:- 1. It is a linear sequential life cycle model it is also called classical model. it is proposed by Royce so that it is called as Royce model

2. when the requirement of the customer is clear then we preferred to use waterfall model.

3. when the size of project is small it is preferably used.

4. in waterfall model we cant start the next phase unless and until the does not complete previous phase.

Prototype Model:- 1.when the requirement of customer is unclear and certainly changing at that time prototype model are used.

2. in this model generally evolved a customer interaction.

3. typically online system,web interface have a very high amount of interaction with end user are best suited for prototype model

Waterfall model is step by step process
Spiral Model is Iterative Process
Prototype Model is certainly changing Process
