梦到老公
Answer (Section 1.1):
Software is both a product and a vehicle for delivering a product. As a product, software is an information transformer. As a vehicle for delivering a product, software rves as a basis for computer control, communication, and creation of other programs.
2.How do software characteristics differ from hardware characteristics?
Answer (Section 1.2):
Software is developed, not manufactured. Software does not wear out. Most software is custom built, not asmbled out of components.

3.Explain what is wrong with the notion that computer software does not need to evolve over time.
Answer (Section1.1):
Computer software must be revid as errors are discovered and corrected. Software must be updated to accommodate changes in the computing environment. Many times a customer will request changes to add new functions to an existing product or to accommodate changes in the business environment. Sometimes an older system will need to be reengineered to provide benefits to the ur in a modern context. The bottom line is that software that does not evolve will eventually become unusable.

2.Describe how Polya’s problem solving principles describe the esnce of engineering practice?
Answer (Section 2.3):
∙Understand the problem (communication and analysis)
∙Plan a solution (modeling and design)
∙Carry out the plan (code generation)
∙Examine the result for accuracy (testing and quality assurance)
Final Exam Question
1.Describe the relationships among software engineering process, methods, and tools.
Answer (Section2.1):
Software process defines the framework that must be established for effective delivery of software engineering technology, by providing a context by which the software engineering methods are applied. Software engineering methods provide the technical ho
w-to’s for building software. Software engineering tools provide automated or mi-automated support for software engineering process and methods.
Chapter 3 - Test Questions
1.How are tasks, actions, and activities related to software process models?
Answer (Section 3.1):
A software process is made up of activities. Each activity is defined by a t of engineering actions. Each activity is defined by a task t that indentifies the work items to be completed.
2.How does software team choo the task t for a particular project?
Answer (Section 3.3):
The software choos the task t bad on the characteristics of the team, the project, and the problem to be solved.
3.How can process patterns assist a development team build software products efficiently?
Answer (Section 3.4):
白芍生菜Process patterns are proven solutions to commonly encountered development problems. If developers can recognize that that this is problem en before they can u a previously known means of solving it, without have to take the time to invent a new solution.

Chapter 4 - Test Questions
1.Describe the phas of the prototyping model for software development?
Answer (Section 4.1.3):
Requirements are gathered by having the customer and developer meet and identify whatever objectives and requirements they can. Quick design follows, focusing on reprentation of the software that will be visible to the customer. A prototype is constructed by the developer and evaluated by the customer and ud to refine the requirements. Iteration occurs and the prototype is tuned to satisfy the customer's needs.
2.What are the primary advantages of the component-bad process model for software engineering?
Answer (Section 4.2.1):
Component-bad process models promote software reu and reusability and can result in: 70% reduction in development cycle times, 84% reduction in project costs, and 70% increa in productivity.
