OPERATING SYSTEM CONCEPTS 9TH EDITION INSTRUCTOR MANUAL

In this chapter, you will learn to: To describe the basic organization of computer systems, to provide a grand tour of the major components of operating systems, to give an overview of the many types of computing environments, to explore several open-source operating systems.

After studying this chapter, you should be able to: Describe the various approaches to virtualization, understand the processor issues involved in implementing a virtual machine, understand the memory management issues involved in implementing a virtual machine, understand the I/O management issues[r]

Windows FirewallCurrent versions of Microsoft Windows (all editions of XP with Service Pack2 installed, plus all editions of Vista) come with Windows Firewall. When youinstall or activate the operating system, the firewall is automatically turnedon. See Figure 2-1.If you install a thir[r]

In this chapter, the learning objectives are: Discuss fraud and the principles of internal control, identify the basic concepts of an accounting information system, describe the nature and purpose of a subsidiary ledger, explain how companies use special journals in journalizing.

The main contents of this chapter include all of the following: Computer system operation, I/O structure, storage structure, storage hierarchy, hardware protection, general system architecture.

Chapter 32 - Cisco IT Essentials Useful Practical Tips (Operating systems). The following will be discussed in this chapter: Brands and versions of operating systems, operating systems capabilities, network operating system (NOS), Windows OS directory structure,...

This chapter examines some more advanced concepts related to process management, which are found in a number of contemporary operating systems. We show that the concept of process is more complex and subtle than presented so far and in fact embodies two separate and potentially independent concepts:[r]

Discuss basic concepts related to concurrency, such as race conditions, OS concerns, and mutual exclusion requirements; understand hardware approaches to supporting mutual exclusion; define and explain semaphores; define and explain monitors;...

This chapter examines two problems that plague all efforts to support concurrent processing: deadlock and starvation. We begin with a discussion of the underlying principles of deadlock and the related problem of starvation. Then we examine the three common approaches to dealing with deadlock: preve[r]

The contents of this chapter include all of the following: Discuss the principal requirements for memory management, understand the reason for memory partitioning and explain the various techniques that are used, understand and explain the concept of paging,...

After studying this chapter, you should be able to: Summarize key categories of I/O devices on computers, discuss the organization of the I/O function, explain some of the key issues in the design of OS support for I/O, analyze the performance implications of various I/O buffering alternatives,...

The various processes in an operating system must be protected from one another’s activities. For that purpose, various mechanisms exist that can be used to ensure that the files, memory segments, CPU, and other resources can be operated on by only those processes that have gained proper authorizati[r]

In this chapter, we discuss various ways to manage memory. The memory- management algorithms vary from a primitive bare-machine approach to paging and segmentation strategies. Each approach has its own advantages and disadvantages. Selection of a memory-management method for a specific system depends[r]

The objectives of this chapter are to introduce the notion of a process a program in execution, which forms the basis of all computation; to describe the various features of processes, including scheduling, creation, and termination; to explore interprocess communication using shared memory and mes-[r]

In this chapter, we introduce many concepts associated with multithreaded computer systems, including a discussion of the APIs for the Pthreads, Windows, and Java thread libraries. We look at a number of issues related to multithreaded programming and its effect on the design of operating systems. F[r]

Chapter 17 examines various mechanisms for process synchronization and communication, as well as methods for dealing with the deadlock problem, in a distributed environment. In addition, since a distributed system may suffer from a variety of failures that are not encountered in a centralized system[r]

After studying this chapter you will be able to develop a description of deadlocks, which prevent sets of concurrent processes from completing their tasks; to present a number of different methods for preventing or avoiding deadlocks in a computer system.
