WaterFall Model: This is a flow based model, in which u
pass every phase once, and can not go back to that phase
again. That is why, it is used rarely now a days.

Drawback: If there is nay change in requirements, then u
can not make any chnages in requirements.

Iterative Model: In this u can come back to previous
phases, and make the changes accordingly. In this we
revieved a final output product at the end of the SDLC.

Prototype Model: Here, we recieved Prototypes of the
product, before the final release. We relaese 4-5 Protypes
with some diffrences b/w them, and take client opinion, and
modifies the final Product, as per client suggestions.

Answer / snr

Waterfall model: It includes all phases of SDLC.The
drawback is once the requirements request made
freezed,changes can't be done during any phase.

Iterative model: We can change requiremnts at any phase,
but the problem is all the phases of SDLC can take place
again.

Prototype model: We can change requirements before design
and coding can proceed.In this model, prototype is
developed based on the currently known
requirements.Development of prototype undergoes design,
coding, testing, which give client an actual feel of the
system. Prototype is a model which looks exactly like SDLC

Answer / himanshu sharma

WATERFALL MODEL:-in this model all the phase of SDLC perform only once.there is no chance to modification in any previous phase. This is same as one way pipeline ."only outgoing allow".
ITERRATIVE WF MODEL:-in this model we can make changes in previous phase according to our need .
PROTOTYPE MODEL:-it is just like a toy implementation of any product.before the product finalize we built a toy which fullfil the requirment of customer ,and we say to the customer that your product will be like our this toy. if customer like this model ,we develop main product.........thanks

Answer / amit raj

Water fall takes one task/activity at a time. the successor task/activity does not start unless the predecessor is completed.

In Iterative methodology, project starts and takes a cyclic path, and may many cycles before it is finished.

I tried to explain in few words, I don't know how much did I convey. It needs a long writing to explain both.

Answer / asha salaama

In a waterfall model no feedback path to the proceeding phases of the Software Development Life Cycle.
while
In the iterative model a feedback path is introduced in each phase of the software life cycle.
