SOFTWARE ENGINEERING

Detailed explanation-1: -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. In a waterfall model, each phase must be completed before the next phase can begin and there is no overlapping in the phases.

Detailed explanation-2: -It is also called a linear sequential model, classic life cycle or waterfall model. It suggests a systematic, sequential approach to Software Development that begins at a systematic level and progresses through communication, planning, modeling, construction, and deployment.

Detailed explanation-3: -The Waterfall methodology-also known as the Waterfall model-is a sequential development process that flows like a waterfall through all phases of a project (analysis, design, development, and testing, for example), with each phase completely wrapping up before the next phase begins.

Detailed explanation-4: -The waterfall model is a breakdown of project activities into linear sequential phases, meaning they are passed down onto each other, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. The approach is typical for certain areas of engineering design.
