Chapter 2 is concerned with the operating-system interfaces that users (or
at least programmers) actually see: system calls. The treatment is somewhat
vague since more detail requires picking a specific system to discu
Virtual memory can be a very interesting subject since it has so many different
aspects: page faults, managing the backing store, page replacement, frame
allocation, thrashing, page size. The objectives of this chapter are to expl
Although many systems are demand paged (discussed in Chapter 10), there are
still many that are not, and in many cases the simpler memory-management
strategies may be better, especially for small dedicated systems. We want the
CPU scheduling is the basis of multiprogrammed operating systems. By switching the CPU among processes, the operating system can make the computer
more productive. In this chapter, we introduce the basic scheduling concepts
In this chapter we introduce the concepts of a process and concurrent execution;
These concepts are at the very heart of modern operating systems. A process
is a program in execution and is the unit of work in a modern time-sharing
Chapter 1 introduces the general topic of operating systems and a handful of
important concepts (multiprogramming, time sharing, distributed system, and
so on). The purpose is to show why operating systems are what they are by
Deadlock is a problem that can arise only in a system with multiple active
asynchronous processes. It is important that the students learn the three basic
