Real-time systems and applications can be classified in sev-eral ways. One classification divides them in two classes:“hard” real-time and “soft” real-time.A hard real-time system is characterized by the fact thatmeeting the applications’[r]

In this chapter, we examine one of the most important and widely used categories of operating systems: embedded operating systems. The embedded system environment places unique and demanding requirements on the OS and calls for design strategies quite different than that found in ordinary operating[r]

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,...

In previous chapter, we introduced threads to the process model. On operating systems that support them, it is kernel-level threads not processes that are in fact being scheduled by the operating system. However, the terms process scheduling and thread scheduling are often used interchangeably. In t[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]

Chapter 16 looks at the current major research and development in distributed-file systems (DFS). The purpose of a DFS is to support the same kind of sharing when the files are physically dispersed among the various sites of a distributed system.

The objectives of this chapter are to describe the services an operating system provides to users, processes, and other systems; to discuss the various ways of structuring an operating system, to discuss the various ways of structuring an operating system.

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 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]

In this chapter, we discuss various mechanisms to ensure the orderly execution of cooperating processes that share a logical address space, so that data consistency is maintained.
