MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Winston Royce introduced the Waterfall Model in 1970.This model has five phases: Requirements analysis and specification, design, implementation, and unit testing, integration and system testing, and operation and maintenance. The steps always follow in this order and do not overlap.

Detailed explanation-2: -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-3: -Implementation As the name implies, in this phase the source code is written as per requirements. The physical design specifications are turned into a working code. The system is developed in small programs called units, after which these units are integrated.

Detailed explanation-4: -The steps include Requirements Determination, Design, Implementation, Verification, and Maintenance.
