Major difference between waterfall and iterative model is that waterfall model has a linear process in which full product is available after the last phase, while incremental model full product is available after several such phases.
In waterfall model, once we come out of the phase, there is no chance of modifying it again. This is one of the major drawback for waterfall model.
Waterfall is one of the software development life cycle model. Waterfall model has five stages.

the waterfall model gives us prototyping , and spirl model gives us product , so the set of the waterfall accommodat in the spirl to gives us this product.
1.spiral model can be accommodate in prototyping and waterfall model. it is a model of iterative process as prototyping and also a systematic approach to solve a problem as in waterfall model. 2. spiral model take problem as a series of step to solve a problem as in waterfall, and take the contribution of users or customers in each phase as in prototyping model.
because, there can be back process of every step in waterfall model, see the book of software engg by somerville.
The Waterfall Model is the oldest and most well-known SDLC model. The distinctive feature of the Waterfall model is its sequential step-by-step process from requirements analysis to maintenance.
Major difference between waterfall and iterative model is that waterfall model has a linear process in which full product is available after the last phase, while incremental model full product is available after several such phases.
A waterfall model is a process that was used to develop and manufacture a product before computers became so commonplace. Because it was too cost prohibitive to make changes after the fact, a company used a waterfall model to develop their product. The stages of a waterfall modes are: Conceive, Design, Implement, Test, Deliver.
The waterfall model is the oldest paradigm for software engeneering. However , over the past two decades,criticism of this process model has caused even ardent supporters to question its efficiency.The waterfall model, sometimes called the classic life cycle, suggests a systematic, sequential approaches to software development.
In waterfall model, once we come out of the phase, there is no chance of modifying it again. This is one of the major drawback for waterfall model.
Waterfall is one of the software development life cycle model. Waterfall model has five stages.
Advantage of waterfall model : It is simple and easy to use. Dis Advantage of waterfall model : no user feedbacks are taken.
