Detailed explanation-1: -The V-model is an SDLC model where execution of processes happens in a sequential manner in a V-shape. It is also known as Verification and Validation model. The V-Model is an extension of the waterfall model and is based on the association of a testing phase for each corresponding development stage.

Detailed explanation-2: -The V model is a simple variant of the traditional waterfall model of system or software development. As illustrated in Figure 1, the V model builds on the waterfall model by emphasizing verification and validation.

Detailed explanation-3: -In the V-Model, the probability of total number of defects in the development of application is low as testing is done in parallel to the development. In the Waterfall Model, the probability of total number of defects in the development of application is high as testing is done post development.

Detailed explanation-4: -In software development, the V-model represents a development process that may be considered an extension of the waterfall model, and is an example of the more general V-model. Instead of moving down in a linear way, the process steps are bent upwards after the coding phase, to form the typical V shape.

Detailed explanation-5: -The waterfall model is a sequential design process in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception, Initiation, Analysis, Design, Construction, Testing, Production/Implementation, and Maintenance.

Detailed explanation-6: -Implementation. The software architecture designed in the design phase is implemented in the implementation phase, which includes software programming, troubleshooting, and module testing. In the implementation phase, the software design is implemented in the desired programming language.

Detailed explanation-7: -The Waterfall Model was the first Process Model to be introduced. It is also referred to as a linear-sequential life cycle model. It is very simple to understand and use.
