  • Lecture Operating system concepts - Chapter 2: Computer-system structures

    Lecture Operating system concepts - Chapter 2: Computer-system structures

    Chapter 2 discusses the general structure of computer systems. It may be a good idea to review the basic concepts of machine organization and assembly language programming. The students should be comfortable with the concepts of memory, CPU, registers, I/O, interrupts, instructions, and the instruction execution cycle. Since the operating system is the interface between the hardware and user programs, a good understanding of operating systems...

  • Lecture Operating system concepts - Chapter 4: Processes

    Lecture Operating system concepts - Chapter 4: Processes

    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 is a program in execution and is the unit of work in a modern time-sharing system. Such a system consists of a collection of processes: Operating-system processes executing system code and user processes executing user code. All these processes can potentially execute concurrently, with...

  • Lecture Operating system concepts - Chapter 6: CPU scheduling

    Lecture Operating system concepts - Chapter 6: CPU scheduling

    In chapter 4, 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 this chapter, we use process scheduling when discussing general scheduling concepts and thread scheduling to refer to thread-specific ideas.

  • Lecture Operating system concepts - Chapter 3: Operating-system structures

    Lecture Operating system concepts - Chapter 3: Operating-system structures

    Chapter 3 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 discuss. This chapter is best supplemented with exactly this detail for the specific system the students have at hand. Ideally they should study the system calls and write some programs making system calls. This chapter also ties...

    Lecture Operating system concepts - Chapter 8: Deadlocks

    Lecture Operating system concepts (Sixth ed) - Chapter 8: Deadlocks. 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.

  • Lecture Operating system concepts - Chapter 7: Process synchronization

    Lecture Operating system concepts - Chapter 7: Process synchronization

    Chapter 7 is concerned with the topic of process synchronization among concurrently executing processes. Concurrency is generally very hard for students to deal with correctly, and so we have tried to introduce it and its problems with the classic process coordination problems: mutual exclusion, bounded-buffer, readers/writers, and so on. An understanding of these problems and their solutions is part of current operating-system theory and...

  • Lecture Operating system concepts - Chapter 5: Threads

    Lecture Operating system concepts - Chapter 5: Threads

    The process model introduced in Chapter 4 assumed that a process was an executing program with a single thread of control. Many modern operating systems now provide features for a process to contain multiple threads of control. This chapter introduces many concepts associated with multithreaded computer systems and covers how to use Java to create and manipulate threads. We have found it especially useful to discuss how a Java thread maps to...
