How does ISO/IEC 25010 address the issue of software maintainability and its sub-characteristics?
- It defines a new programming language.
- It provides guidelines for web design.
- It outlines a framework for software quality characteristics and sub-characteristics, including maintainability.
- It specifies hardware requirements.
ISO/IEC 25010 is an international standard that defines a framework for software quality characteristics and sub-characteristics. Among these characteristics is "Maintainability," which includes various sub-characteristics like "Analyzability," "Modifiability," and "Testability." It offers a structured way to assess and improve the maintainability of software systems.
What role does Version Control play in the context of Software Configuration Management?
- It restricts access to software components
- It helps manage different versions of software artifacts
- It enforces project deadlines
- It ensures that code is error-free
Version Control in SCM plays a crucial role in managing different versions of software artifacts. It enables teams to track changes, roll back to previous versions, and collaborate effectively on code and documentation, ensuring traceability and version history.
Consider a scenario where a software system, after a certain period, starts to decline in performance and user satisfaction. Discuss how different software evolution models might be deployed to revive and enhance the system.
- Use a patchwork approach
- Apply a complete system rewrite
- Implement performance optimization
- Continue with the existing system
When a software system experiences performance and user satisfaction issues, it's essential to consider performance optimization as a software evolution strategy. This involves identifying bottlenecks and improving system efficiency to enhance performance. A complete rewrite is costly and risky, and patchwork approaches may not address the root issues. Performance optimization is a targeted approach for improvement.
Why is it important to isolate the unit from the rest of the software system during Unit Testing?
- To make testing faster
- To reduce the cost of testing
- To simplify the testing process
- To identify defects in the unit without interference
Isolating the unit from the rest of the software system during Unit Testing is essential to identify defects in the unit without interference from other components. It allows testers to focus on the specific unit being tested, making it easier to detect and address issues within that unit. This isolation is crucial for effective Unit Testing.
Fill in the blank: "The _____ attribute relates to the ease with which a software product can be transferred from one hardware or software environment to another."
- Scalability
- Reliability
- Portability
- Usability
Portability is the attribute that concerns the ease of transferring a software product from one environment to another, be it different hardware, software, or operating systems. This is important for making software versatile and adaptable.
Which form of integration testing focuses on verifying the integration between different systems or subsystems?
- Top-Down Integration Testing
- Bottom-Up Integration Testing
- Unit Integration Testing
- Incremental Integration Testing
Top-Down Integration Testing focuses on verifying the integration between different systems or subsystems within a software application. It starts with testing the highest-level modules first and progressively integrates lower-level modules.
In GraphQL, the _____ defines the operations that can be performed to access the data.
- Server
- Resolver
- Schema
- Query
In GraphQL, the "Schema" defines the operations that can be performed to access the data. The schema specifies the types of data that can be queried and the structure of those queries.
During stress testing, its vital to monitor system parameters like CPU usage, memory usage, and ______ to evaluate performance under stress.
- Network latency
- Software licensing
- User satisfaction
- Battery life
During stress testing, it's important to monitor system parameters like CPU usage, memory usage, and network latency. This allows for a comprehensive evaluation of the system's performance under stress, including how it handles network-related challenges.
How does the Maintainability Index (MI) provide insights into the future perspectives of a software product?
- MI assesses project budget
- MI measures code complexity and maintainability
- MI evaluates user satisfaction
- MI predicts market demand
The Maintainability Index (MI) provides insights into the future perspectives of a software product by measuring code complexity and maintainability. A higher MI score indicates that the code is easier to maintain, reducing the cost and effort required for future enhancements or bug fixes.
What is a key benefit of software re-engineering in relation to system performance?
- Improved user interface
- Enhanced security
- Increased speed and efficiency
- Better hardware compatibility
Software re-engineering can lead to increased speed and efficiency. By optimizing and modernizing software, it can run faster and more efficiently, improving system performance. This can involve optimizing code, upgrading data structures, and other enhancements.
