Detailed explanation-1: -Answers. The linear sequential model is also known as the classic life cycle or the waterfall model.
Detailed explanation-2: -Waterfall 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-3: -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-4: -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-5: -The waterfall model is a linear, sequential approach to the software development lifecycle (SDLC) that is popular in software engineering and product development.
