In this section of Software Engineering.It contain Software Engineering Basics MCQs (Multiple Choice Questions Answers).All the MCQs (Multiple Choice Question Answers) requires in depth reading of Software Engineering Subject as the hardness level of MCQs have been kept to advance level.These Sets of Questions are very helpful in Preparing for various Competitive Exams and University level Exams.
1. Which question no longer concerns the modern software engineer?
- Why does computer hardware cost so much?
- Why does software take a long time to finish?
- Why does it cost so much to develop a piece of software?
- Why can’t software errors be removed from products prior to delivery?
These, and many other questions, are a manifestation of the concern about software and the manner in which it is developed—a concern that has lead to the adoption of software engineering practice.
- Why does it take so long to get software finished?
- Why are development costs so high?
- Why can’t we find all errors before we give the software to our customers?
- Why do we spend so much time and effort maintaining existing programs?
- Why do we continue to have difficulty in measuring progress as software is being developed and maintained?
2. Software is a product and can be manufactured using the same technologies used for other engineering artifacts
- True
- False
The characteristics of software that make it different from other things that human beings build. Software is a logical rather than a physical system element. Therefore, software has characteristics that are considerably different than those of hardware.
3. Software deteriorates rather than wears out because
- Software suffers from exposure to hostile environments
- Defects are more likely to arise after software has been used often
- Multiple change requests introduce errors in component interactions
- Software spare parts become harder to order
During its life, software will undergo change. As changes are made, it is likely that errors will be introduced, causing the failure rate curve to spike that means the software is deteriorating due to change.
4. WebApps are a mixture of print publishing and software development, making their development outside the realm of software engineering practice.
- True
- False
5. There are no real differences between creating WebApps and MobileApps
- True
- False
6. In its simplest form an external computing device may access cloud data services using a web browser.
- True
- False
7. Product line software developments depends the reuse of existing software components to provide software engineering leverage.
- True
- False
8. Which of the items listed below is not one of the software engineering layers?
- Process
- Manufacturing
- Methods
- Tools
Software engineering is a layered technology
- any engineering approach (including software engineering) must rest on an organizational commitment to quality. Total quality management, Six Sigma.
- The foundation for software engineering is the process layer. The software engineering process is the glue that holds the technology layers together and enables rational and timely development of computer software.
- Software engineering methods provide the technical how-to’s for building software. Methods encompass a broad array of tasks that include communication, requirements analysis, design modeling, program construction, testing, and support.
- Software engineering tools provide automated or semi automated support for the process and the methods
9. Software engineering umbrella activities are only applied during the initial phases of software development projects.
- True
- False
The process framework encompasses a set of umbrella activities that are applicable across the entire software process.
10. Which of these are the 5 generic software engineering framework activities?
- communication, planning, modeling, construction, deployment
- communication, risk management, measurement, production, reviewing
- analysis, designing, programming, debugging, maintenance
- analysis, planning, designing, programming, testing
A generic process framework for software engineering encompasses five activities:
1.Communication
2.Planning.
3.Modeling
4.Construction
5.Deployment
11. Planning ahead for software reuse reduce the cost and increases the value of the systems into which they are incorporated
- True
- False
Plan Ahead for Reuse:
Reuse saves time and effort. Achieving a high level of reuse is arguably the hardest goal to accomplish in developing a software system. The reuse of code and designs has been proclaimed as a major benefit of using object-oriented technologies.To leverage the reuse possibilities that object-oriented [or conventional] programming provides requires forethought and planning.
12. The essence of software engineering practice might be described as understand the problem, plan a solution, carry out the plan, and examine the result for accuracy.
- True
- False
The essence of software engineering practice:
- Understand the problem (communication and analysis).
- Plan a solution (modeling and software design)
- Carry out the plan (code generation)
- Examine the result for accuracy (testing and quality assurance)
13. In agile process models the only deliverable work product is the working program.
- True
- False
Reality: A working program is only one part of a software configuration that includes many elements. A variety of work products (e.g., models, documents, plans) provide a foundation for successful engineering and, more important, guidance for software support.
14. A most software development projects are initiated to try to meet some business need.
- True
- False
Every software project is precipitated by some business need—the need to correct a defect in an existing application; the need to adapt a “legacy system” to a changing business environment; the need to extend the functions and features of an existing application; or the need to create a new product, service, or system.
15. In general software only succeeds if its behavior is consistent with the objectives of its designers.
- True
- False
The market will accept the product only if the software embedded within it properly meets the customer’s (as yet unstated) needs.
16. Today the increased power of the personal computer has brought about an abandonment of the practice of team development of software.
- True
- False
17. Most software continues to be custom built because
- Component reuse is common in the software world.
- Reusable components are too expensive to use.
- Software is easier to build without using someone else's components.
- Off-the-shelf software components are unavailable in many application domains.
18. The nature of software applications can be characterized by their information
- Complexity
- Content
- Determinacy
- both b and c
19. Modern software applications are so complex that it is hard to develop mutually exclusive category names.
- True
- False
20. The so called "new economy" that gripped commerce and finance during the 1990s died and no longer influences decisions made by businesses and software engineers.
- True
- False
21. The functionality of most computer systems does not need to be enhanced the lifetime of the system.
- True
- False
22. Change cannot be easily accommodated in most software systems, unless the system was designed with change in mind.
- True
- False
