Detailed explanation-1: -Definition: The waterfall model is a classical model used in system development life cycle to create a system with a linear and sequential approach. It is termed as waterfall because the model develops systematically from one phase to another in a downward fashion.

Detailed explanation-2: -The sequential model (also known as the KNF model) is a theory that describes cooperativity of protein subunits. It postulates that a protein’s conformation changes with each binding of a ligand, thus sequentially changing its affinity for the ligand at neighboring binding sites.

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.
