Fill in the blank: "_____ refers to the ability of software to be understood, learned, used, and attractive to the user when used under specified conditions."
- Scalability
- Reliability
- Portability
- Usability
Usability is all about the user experience. It refers to how easy it is for users to understand, learn, and use the software effectively under specific conditions. High usability is crucial for user satisfaction and productivity.
The _____ architecture style is known for developing a system as a collection of smaller independent units.
- Monolithic
- Microservices
- Client-Server
- Peer-to-Peer
The Microservices architecture style is known for developing a system as a collection of smaller independent units. In this architecture, the application is composed of loosely coupled, independently deployable services, which makes it easier to develop, test, and scale.
In UI Design, what does "Fittss Law" pertain to?
- Ease of learning
- Designing for touch screens
- Human-computer interaction
- Predicting the time to acquire a target
Fitts's Law is a model in human-computer interaction that predicts the time it takes to acquire a target in a user interface. It is often used to design and optimize user interfaces for efficiency and ease of use.
How does regression testing ensure the consistent functionality of software after changes have been made?
- By retesting all test cases
- By testing only the modified code
- By retesting the entire system
- By comparing the new version with the previous one
Regression testing ensures the consistent functionality of software after changes by retesting the entire system. This practice helps identify any unintended side effects of code changes and ensures that the software continues to work correctly across all its features.
Why is regression testing crucial when implementing a new feature within an existing system?
- It speeds up the development process
- It helps reduce the cost of development
- It ensures that new features do not break existing functionality
- It is a formality without much impact
Regression testing is crucial when implementing a new feature within an existing system because it helps ensure that the introduction of new features does not lead to the breaking of existing functionality. This is essential for maintaining the software's stability and quality.
Software reverse engineering often involves analyzing ______ to understand how a program works.
- Source code
- User interface
- Hardware components
- User documentation
Software reverse engineering typically involves analyzing the source code of a program to understand how it works. Source code contains the instructions and logic that govern the program's behavior. By examining the source code, reverse engineers can gain insights into the program's functionality.
Which design principle aims to manage dependencies between modules effectively?
- Cohesion
- Coupling
- Abstraction
- Inheritance
The design principle that aims to manage dependencies between modules effectively is "Coupling." It refers to the degree of interconnection between modules in a software system. Reducing coupling helps make the system more maintainable and flexible.
The main focus of ______ maintenance is to manage the changes in the software operating environment.
- Corrective
- Adaptive
- Perfective
- Preventive
Adaptive maintenance focuses on managing changes in the software operating environment, such as adapting it to new hardware or software platforms. It ensures the software remains compatible with evolving technology.
In what way does the inflexibility of the Waterfall model regarding changes impact quality assurance throughout the project lifecycle?
- It enhances the quality assurance process
- It has no impact on quality assurance
- It hinders the quality assurance process
- It streamlines the quality assurance process
The inflexibility of the Waterfall model regarding changes can hinder the quality assurance process. In Waterfall, changes are difficult to accommodate once a phase is completed, which can result in quality issues if requirements evolve during the project.
Consider a scenario where a company wants to migrate its monolithic application to microservices to increase scalability. What might be some challenges faced during this transition?
- Tighter integration
- Enhanced scalability
- Data consistency
- Increased development speed
Transitioning from a monolithic application to microservices can indeed lead to challenges such as tighter integration. In a microservices architecture, services are decoupled, which can make integrating them more complex compared to a monolithic system. This challenge is essential to understand for a successful transition.
