What is the Waterfall model in software development?
a) A linear and sequential software development process
b) An iterative process with multiple development cycles
c) A flexible model for rapid development
d) A model where development and testing happen simultaneously
Answer:
a) A linear and sequential software development process
Explanation:
The Waterfall model is a linear and sequential approach to software development. Each phase must be completed before moving on to the next phase, and there is little to no overlap between phases.
Common phases include requirement analysis, system design, implementation (coding), testing, deployment, and maintenance. The Waterfall model is easy to understand and manage, but it lacks flexibility, making it difficult to adapt to changes once a phase is completed.
This model is best suited for projects where requirements are well understood and unlikely to change.
