Which of the following best describes the term "software update"?
- Adding new hardware
- Modifying software code
- Updating software to a newer version
- Upgrading the operating system
A "software update" refers to the process of updating software to a newer version. These updates typically include bug fixes, new features, and security improvements, ensuring the software's optimal performance.
The practice of _____ ensures that the codebase is continuously tested, helping to identify issues early in the development process.
- Code Review
- Continuous Integration
- Manual Testing
- User Acceptance Testing
Continuous Integration (CI) ensures that the codebase is continuously tested, often automatically, helping to identify issues early in the development process, promoting quality and collaboration.
A project manager is overseeing a large and complex software development project. What benefits would implementing a structured SDLC bring to this project?
- Better risk management
- Faster development
- Increased flexibility
- Reduced documentation
Implementing a structured SDLC, like Waterfall, offers better risk management. It allows for comprehensive planning and risk assessment, crucial for large and complex projects.
The principle of _______ in Object-Oriented Programming suggests that a class should have only one reason to change.
- DRY
- KISS
- SOLID
- YAGNI
The principle of SOLID in Object-Oriented Programming, specifically the Single Responsibility Principle (SRP), suggests that a class should have only one reason to change. This promotes maintainability and a clear design.
Traditional SDLC models often face the limitation of ______ when dealing with changing requirements.
- Adaptability
- Lack of planning
- Limited documentation
- Rigidity
Traditional SDLC models often face the limitation of rigidity when dealing with changing requirements. These models often have well-defined phases and may struggle to accommodate changing requirements, making them less adaptable.
What is the main objective of performance testing in software development?
- Ensure 100% code coverage.
- Identify and fix all defects.
- Validate user interface design.
- Verify if the software meets specified performance criteria
The main objective of performance testing is to verify if the software meets the specified performance criteria, such as response time, scalability, and resource utilization. It helps ensure the software's performance is acceptable.
The process of tracing and identifying the origin of requirements is facilitated by the use of a __________ matrix.
- Requirements
- Stakeholder
- Traceability
- Validation
Traceability matrices are used to trace and identify the origin of requirements. They help ensure that each requirement is linked to its source and that nothing is missed during the development process.
Imagine a scenario where a user identifies a bug in a mobile application and reports it through the app's feedback system. What steps would typically follow in the bug tracking and resolution process?
- The bug is documented and prioritized.
- The bug is fixed immediately.
- The bug is ignored by the development team.
- The user is asked for payment.
Bug tracking and resolution typically involve documenting the reported bug, prioritizing it based on its impact and severity, assigning it to a developer, fixing it, testing the fix, and then releasing an update. Ignoring or asking for payment is not standard practice.
Why is it important to clearly define both functional and non-functional requirements before the development phase begins?
- Clear requirements help in creating a shared understanding and reduce misunderstandings.
- It saves time if you define requirements later in the project.
- It's not essential; you can define them as you go.
- Non-functional requirements are less important than functional requirements.
Clearly defining both functional and non-functional requirements is crucial to ensure that everyone involved in the project understands what needs to be built. This shared understanding reduces misunderstandings and minimizes rework, leading to a more successful project.
What is the primary goal of using prototyping models in software development?
- To complete the project faster
- To create the final product early
- To document the requirements
- To identify and eliminate errors
The primary goal of using prototyping models in software development is to create an early version of the final product to better understand and validate the user requirements and design.
