1. For each of the most popular commands in Windows, identify the type of operating system service that is being provided, and identify the basic module or modules that are involved. Which commands would you assume are memory resident and which loaded as required? Explain your assumptions.

2. Concurrency, of course, is a requirement for modern operating systems. What are the major challenges that an OS designer faces in supporting efficient concurrency that she would not face if the operating system could just run one program at a time?

3. An operating system is described as an event-driven program. What is meant by event driven? Explain how the dispatching operation fits this description.

4. Early versions of Windows did not support true preemptive multitasking. Instead, the designers of Windows provided something they called ''cooperative multitasking'' in which each program was expected to give up control of the CPU at reasonable time intervals, so that the Windows dispatcher could provide execution time to another waiting program. Describe the disadvantages of this method.

5. One approach to operating system design is to provide as small a kernel as possible and to make all other modules optional. What are the minimum services that must be provided in such a miniature kernel?

6. What operating system functions would you expect to find in the computer that is built in to control your automobile, and which functions would be omitted? Justify your answer.

please look in chapter 15 for the questions.
