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

Explain how both the waterfall model of the software process and the prototyping model can be accommodated in the spiral process model?
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.
What is advantage of using prototyping model instead of using waterfall model?
There are many advantages of using prototype model over waterfall model . Some of the advantages are: 1) Excellent for gathering and refining requirements. 2) Useful for assessing and reducing risks.
What is the difference between waterfall model iterative waterfall model prototyping model and spiral model?
The Waterfall model is a linear sequential approach to software development in which each phase of the development process must be completed before moving on to the next. The Iterative Waterfall model is similar to the Waterfall model, but includes a feedback loop in which each phase is revisited and revised based on feedback from the previous phase. The Prototyping model is an iterative approach to software development in which a prototype is created and refined based on feedback from users and stakeholders. This model is often used for projects with high levels of uncertainty or where requirements are not well-defined. The Spiral model combines elements of both the Waterfall and Prototyping models, with each iteration of the development process consisting of four phases: planning, risk analysis, engineering, and evaluation. This model emphasizes risk management and allows for flexibility and adaptation throughout the development process. Overall, the main differences between these models lie in their approach to project management and development, with each model offering its own set of advantages and disadvantages depending on the specific needs of the project.
What is the main Criterion for deciding whether or not to use waterfall model in a software development project?
The critieria is based on what other techniques you might employ. The waterfall method in SDLC (software development life cycle) has been largely discounted in favor of more effective methods, such as the iterative approach. One of the main problems with the waterfall design is that it does not easily allow for negative feedback at several stages of the project (for example, water flows downhill, not uphill, so feedback into the cycle can be very costly).
Waterfall model advantages and disadvantages?
Advantage of waterfall model : It is simple and easy to use. Dis Advantage of waterfall model : no user feedbacks are taken.
Waterfall model and prototyping model can be accommodated in spiral model?
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.

What is the iterative waterfall?
Iterative waterfall model is a software process model also called the incremental process model. http://en.wikipedia.org/wiki/Iterative_and_incremental_development
Deference between classical waterfall model and iterative waterfall model?
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.

Waterfall or spiral model of railway reservation system?
spiral model is iterative model hence its easy to implement it .
List few of the System Development methodologies?
agile methodology, spiral, iterative, waterfall, model-driven development architecture
Explain what linear programming is and what the various models are?
the sequential flow of processes usually linear and its has two types which are: Waterfall and Prototyping Model
Waterfall model is suitable for which system with justification?
SDLC + Software Prototyping commonly used to develop organisational information systems
What is incremental model explain in detail?
The incremental build model is a method of software development where the model is designed, implemented and tested incrementally (a little more is added each time) until the product is finished. It involves both development and maintenance. The product is defined as finished when it satisfies all of its requirements. This model combines the elements of the waterfall model with the iterative philosophy of prototyping.
What are the traditional lifecycle models for software development?
The primary one is called "Waterfall" because it all goes one way, never back.
Is XP an upgraded form of Waterfall and Iterative models?
Hello: It depends on what you would like to call as an upgraded version. XP and the super set - Agile is much more than just iterative and incremental. You can check out this article found out by a Google search for more: http://www.agilecollab.com/iterative-and-incremental-is-not-equal-to-agile-key-aspects-of-agile Thanks
