Lecture Operating system concepts (Fifth edition): Module 15 - Avi Silberschatz, Peter Galvin
Module 15 - Network structures. In a distributed (loosely coupled) system, the processors do not share memory or a clock. Instead, each processor has its own local memory. The processors communicate with one another through various communication networks, such as high-speed buses or telephone lines. In this chapter, we discuss the general structure of distributed systems and the networks that interconnect them. Detailed discussions are given in chapters 16 to 18.

Lecture Operating system concepts (Fifth edition): Module 19 - Avi Silberschatz, Peter Galvin
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 authorization from the operating system. In this chapter, we examine the problem of protection in great detail and develop a unifying model for implementing protection.

Lecture Operating system concepts (Fifth edition): Module 20 - Avi Silberschatz, Peter Galvin
The information stored in the system (both data and code), as well as the physical resources of the computer system, need to be protected from unauthorized access, malicious destruction or alteration, and accidental introduction of inconsistency. In this chapter, we examine the ways in which information may be misused or intentionally made inconsistent. We then present mechanisms to guard against this occurrence.

Lecture Operating system concepts (Fifth edition): Module 21 - Avi Silberschatz, Peter Galvin
Module 21 - The UNIX system. Although operating system concepts can be considered in purely theoretical terms, it is often useful to see how they are implemented in practice. This chapter presents an in-depth examination of the 4.3BSD operating system, a version of UNIX, as an example of the various concepts presented in this lecture. By examining a complete, real system, we can see how the various concepts discussed in this book relate both to one another and to practice.
