Below are several 2-mark questions along with concise answers covering Unit V topics:
COMPUTER-AIDED SOFTWARE ENGINEERING (CASE)
-
What is CASE?
- CASE (Computer-Aided Software Engineering) refers to the use of software tools to support software development activities.
-
What is the scope of CASE?
- The scope of CASE includes automation of software analysis, design, coding, testing, and maintenance processes.
-
What is a CASE environment?
- A CASE environment consists of tools, methodologies, and support systems used in the software development life cycle.
-
How does CASE support the software life cycle?
- CASE tools assist in different phases such as requirement analysis, design, coding, testing, and maintenance.
-
What are the characteristics of CASE tools?
- Characteristics of CASE tools include automation, integration, standardization, and support for documentation.
-
What is a second-generation CASE tool?
- Second-generation CASE tools focus on advanced automation, better integration, and AI-based assistance for software development.
-
What are the components of a CASE environment?
- Components include a repository, user interface, integration mechanism, and toolset for different software development activities.
-
What are the benefits of using CASE tools?
- Benefits include improved productivity, reduced errors, better documentation, and faster development.
-
Give an example of a CASE tool.
- Rational Rose, Enterprise Architect, and Visual Paradigm are examples of CASE tools.
-
What is the architecture of a CASE environment?
- It consists of a central repository, tool integration, user interface, and support components like project management and configuration control.
SOFTWARE MAINTENANCE
- What is software maintenance?
- Software maintenance is the process of modifying and updating software after deployment to correct faults, improve performance, or adapt to changes.
- What are the characteristics of software maintenance?
- It includes high cost, dependency on legacy systems, continuous evolution, and the need for skilled professionals.
- What is software reverse engineering?
- Software reverse engineering involves analyzing software to extract design and implementation details, often used for understanding legacy systems.
- What are the different types of software maintenance?
- The types are corrective, adaptive, perfective, and preventive maintenance.
- What is corrective maintenance?
- Corrective maintenance fixes bugs or defects in the software.
- What is adaptive maintenance?
- Adaptive maintenance involves modifying software to work in a new environment, such as a new OS or hardware.
- What is perfective maintenance?
- Perfective maintenance improves software performance, features, and usability.
- What is preventive maintenance?
- Preventive maintenance involves making changes to prevent future problems and extend the software’s lifespan.
- What are software maintenance process models?
- Common models include the quick-fix model, iterative enhancement model, and reengineering model.
- What factors influence software maintenance cost?
- Factors include software complexity, documentation quality, development process, and hardware/software dependencies.
SOFTWARE REUSE
- What is software reuse?
- Software reuse is the process of using existing software components, code, or modules in new applications to save time and cost.
- Why has software reuse not been widely adopted so far?
- Barriers include lack of standardization, poor documentation, and difficulty in integrating reusable components.
- What are the benefits of software reuse?
- Benefits include reduced development cost, improved productivity, and higher software quality.
- What are the basic issues in software reuse?
- Issues include lack of proper documentation, compatibility problems, licensing concerns, and difficulty in finding reusable components.
- What is a reuse approach?
- A reuse approach involves designing software with reusable components and maintaining a repository of reusable assets.
- How can reuse be implemented at the organizational level?
- By setting up a reuse library, encouraging modular design, and adopting component-based development strategies.
- What is domain engineering in software reuse?
- Domain engineering is the process of developing reusable software components within a specific application domain.
- What is component-based software development (CBSD)?
- CBSD is a software engineering approach that emphasizes building applications using reusable software components.
- What is the difference between white-box and black-box reuse?
- White-box reuse allows modifications to existing components, while black-box reuse uses components as they are without modification.
- What is a software repository in reuse?
- A software repository is a centralized storage system that holds reusable software components and modules.
