Program Development Lifecycle

What happens in the analysis stage of the program lifecycle?

• The problem is defined through a requirements specification, feasibility study, and investigation.

• The program is coded and tested for functionality.

• User feedback is collected to improve the design.

• The final product is deployed to the users.

What is software maintenance?

• Updating the program to fix bugs, improve performance, or adapt it to new requirements.

• Creating new software from scratch.

• Removing outdated features from the software.

• Testing the software for security vulnerabilities.

What is the purpose of a test plan?

• It outlines the marketing strategy for a product.

• It details how a program will be tested, including test cases and expected outcomes.

• It provides a budget for the software development process.

• It describes the user interface design of the application.

What are the key benefits of RAD?

• Fast development, frequent customer feedback, and flexibility for changing requirements.

• Increased documentation and rigid project timelines.

• Limited customer involvement and fixed requirements.

• Longer development cycles and less flexibility.

What is acceptance testing?

• The process of identifying bugs in the software before release.

• The final phase of testing to ensure the program meets user and business requirements.

• A method to evaluate the performance of the software under load.

• A preliminary test to check the functionality of individual components.

What is the purpose of the program development lifecycle?

• To develop well-structured, documented programs that can be maintained and modified as needed.

• To create programs that are only functional without documentation.

• To ensure that programs are developed as quickly as possible without regard for structure.

• To eliminate the need for testing and debugging during development.

What is the Waterfall Model?

• A linear, sequential development approach where each stage is completed before moving to the next.

• An iterative development process that allows for changes at any stage.

• A model that emphasizes continuous delivery and feedback from users.

• A framework that focuses on rapid prototyping and user involvement.

What are the three types of software maintenance?

• Corrective (fix errors), Perfective (improve performance), and Adaptive (modify for new needs)

• Preventive (avoid future problems), Reactive (respond to issues), and Proactive (anticipate needs)

• Functional (add new features), Technical (update technology), and Operational (ensure usability)

• Strategic (long-term planning), Tactical (short-term actions), and Operational (daily tasks)

What are syntax errors in a program?

• Errors caused by incorrect code structure, detected by the compiler or interpreter.

• Errors that occur during runtime due to invalid operations.

• Warnings that suggest improvements in code efficiency.

• Errors that are automatically corrected by the IDE.

What are the advantages of the Waterfall Model?

• It allows for continuous feedback and iteration.

• It is simple to manage, well-documented, suitable for small projects with clear requirements.

• It is highly flexible and adaptable to changes.

• It requires extensive user involvement throughout the development process.
