Answer: A software engineer designs, develops, tests, and maintains software systems using engineering principles.

Question: What are functional requirements?

Answer: Functional requirements specify the actions a system must perform to meet user needs.

Question: What are non-functional requirements?

Answer: Non-functional requirements define system attributes like performance, security, and reliability.

Question: What is software prototyping?

Answer: Software prototyping is creating an early model of a system to understand and refine its requirements.

Question: What is agile methodology?

Answer: Agile methodology emphasizes iterative development, collaboration, and adaptability in software projects.

Question: What is a use case?

Answer: A use case describes how a user interacts with a system to achieve a specific goal.

Question: Define software metrics.

Answer: Software metrics are quantitative measures used to assess software development and performance.

Question: What is a software defect?

Answer: A software defect is an error or flaw in a program that causes incorrect or unintended results.

Question: What is a feasibility study in software engineering?

Answer: A feasibility study assesses the practicality and viability of a proposed software project.

Question: What is configuration management?

Answer: Configuration management tracks and controls changes in software to maintain integrity over time.

Question: What is a design pattern?

Answer: A design pattern is a reusable solution to a common software design problem.

Software Development Models

Question: What is the waterfall model?

Answer: The waterfall model is a sequential development approach where each phase must be completed before moving to the next.

Question: What are the drawbacks of the waterfall model?

Answer: It is inflexible, assumes requirements won’t change, and delays testing until the end of development.

Question: What is the iterative model?

Answer: The iterative model involves repeating software development phases to refine the system progressively.

Question: What is the V-model in software engineering?

Answer: The V-model emphasizes verification and validation in a sequential development approach.

Question: What is the spiral model?

Answer: The spiral model combines iterative development with risk analysis in a cyclic process.

Question: What is the RAD model?

Answer: The Rapid Application Development (RAD) model emphasizes quick development and user feedback through prototypes.

Question: What is the agile model?

Answer: Agile focuses on flexibility, collaboration, and incremental delivery of software.

Question: What is DevOps?

Answer: DevOps integrates development and operations teams to automate and improve the software delivery process.

Question: What is the difference between agile and waterfall models?

Answer: Agile is iterative and flexible, while the waterfall is linear and rigid.

Question: What is the purpose of a project backlog in agile?

Answer: The project backlog lists tasks and features to be completed in a software project.

Question: What is a sprint in agile?

Answer: A sprint is a time-boxed period during which specific tasks are completed in agile development.

Question: What is a user story?

Answer: A user story is a short, simple description of a feature or requirement from the user’s perspective.

Question: What is scrum methodology?

Answer: Scrum is an agile framework for managing and completing complex projects.

Question: What is pair programming?

Answer: Pair programming is a practice where two developers work together at one workstation to write code.

Question: What is the importance of retrospectives in agile?

Answer: Retrospectives help teams review their work process and identify areas for improvement.

Question: What is the purpose of continuous integration?

Answer: Continuous integration ensures code changes are automatically built, tested, and integrated into the main branch.

Question: What is Kanban in software development?

Answer: Kanban is a visual method for managing workflows and tasks in software projects.

Question: What is a burn-down chart?

Answer: A burn-down chart tracks work remaining in a sprint or project over time.

Question: What is test-driven development (TDD)?

Answer: TDD is a practice where tests are written before the code to guide development.

Question: What are key advantages of agile development?

Answer: Agile improves flexibility, collaboration, user satisfaction, and product quality.

Software Testing and Quality Assurance

Question: What is the purpose of software testing?

Answer: Software testing ensures that a system functions correctly and meets specified requirements.

Question: What is black-box testing?

Answer: Black-box testing evaluates software functionality without knowledge of its internal code.

Question: What is white-box testing?

Answer: White-box testing involves testing the internal structures and logic of the code.

Question: What is regression testing?

Answer: Regression testing verifies that changes or updates to software do not introduce new defects.

Question: What is unit testing?

Answer: Unit testing checks individual components of software for correctness.

Question: What is integration testing?

Answer: Integration testing evaluates the interaction between integrated software modules.

Question: What is system testing?

Answer: System testing validates the complete and integrated software system.

Question: What is acceptance testing?

Answer: Acceptance testing ensures the software meets user requirements and is ready for deployment.

Question: What is exploratory testing?

Answer: Exploratory testing involves simultaneous learning, test design, and execution without pre-defined scripts.

Question: What is test automation?

Answer: Test automation uses software tools to execute tests, compare results, and report outcomes.

Question: What are test cases?

Answer: Test cases are specific conditions under which a tester evaluates software functionality.

Question: What is a defect life cycle?

Answer: The defect life cycle tracks the stages of a software defect from discovery to resolution.

Question: What is performance testing?

Answer: Performance testing evaluates the responsiveness, scalability, and stability of a system under load.

Question: What is load testing?

Answer: Load testing assesses how a system performs under expected user loads.

Question: What is stress testing?

Answer: Stress testing evaluates system behavior under extreme conditions.

Question: What is usability testing?
