35. Which two waterfall approach phases are involved?
Answer: A
Design and implementation phases are involved.
The phases of design and implementation in the waterfall approach are integral to the programming process described in the extract. These phases involve creating the program's architecture and developing the actual code that compresses files and manages objects.
A) Design and implementation
This option is correct because the design phase involves defining the structure and components of the program, while the implementation phase is where the actual coding occurs. Both phases are essential for developing a program that meets the requirements outlined in the extract.
B) Design and testing
This option is incorrect because, while the design phase is relevant, the testing phase does not involve the creation of the program itself. Testing is conducted after implementation to ensure the program functions correctly, but it does not contribute to the initial development of the file compression program.
C) Analysis and implementation
This option is incorrect as well. Although analysis is an important phase in the waterfall model, it primarily focuses on gathering requirements rather than the actual design of the system. Implementation follows design, making "analysis and implementation" an incomplete pairing for the context provided.
D) Implementation and testing
This option is also incorrect. While implementation is a relevant phase, testing follows after the implementation phase and is not part of the design and development process of the program. Thus, it does not correctly represent the phases involved in creating the file compression program as described in the extract.
Conclusion
The correct answer is definitively option A, as both the design and implementation phases are crucial in the development of software, particularly for the task of compressing files and managing program objects. Other options either include phases that do not directly contribute to the development process or misrepresent the order and relationship of the phases in the waterfall model.
