Over the past two decades, there has been a huge amount of innovation in both the principles and practice of operating systems Over the same period, the core ideas in a modern operating system - protection, concurrency, virtualization, resource allocation, and reliable storage - have become widely applied throughout computer science. Whether you get a job at Facebook, Google, Microsoft, or any other leading-edge technology company, it is impossible to build resilient, secure, and flexible computer systems without the ability to apply operating systems concepts in a variety of settings. This book examines the both the principles and practice of modern operating systems, taking important, high-level concepts all the way down to the level of working code. Because operating systems concepts are among the most difficult in computer science, this top to bottom approach is the only way to really understand and master this important material.

The main theme of the book is that operating systems are not radically different from other programs. The difficulties encountered in the design of efficient, reliable operating systems are the same as those one encounters in the design of other large programs, such as compilers or payroll programs. This book tries to give students of computer science and professional programmers a general understanding of operating systems - the programs that enable people to share computers efficiently.

Responding to a major shift from single-processor to distributed and parallel computer systems, this compact text integrates those fundamental ideas, principles, and concepts in both centralized and distributed computing that remain constant even as new, more advanced systems are introduced.

The tenth edition of Operating System Concepts has been revised to keep it fresh and up-to-date with contemporary examples of how operating systems function, as well as enhanced interactive elements to improve learning and the student’s experience with the material. It combines instruction on concepts with real-world applications so that students can understand the practical usage of the content. End-of-chapter problems, exercises, review questions, and programming exercises help to further reinforce important concepts. New interactive self-assessment problems are provided throughout the text to help students monitor their level of understanding and progress. A Linux virtual machine (including C and Java source code and development tools) allows students to complete programming exercises that help them engage further with the material. The Print Companion includes all of the content found in a traditional text book, organized the way you would expect it, but without the problems.

This revised and updated Second Edition presents a practical introduction to operating systems and illustrates these principles through a hands-on approach using accompanying simulation models developed in Java and C++. This text is appropriate for upper-level undergraduate courses in computer science. Case studies throughout the text feature the implementation of Java and C++ simulation models, giving students a thorough look at both the theoretical and the practical concepts discussed in modern OS courses. This pedagogical approach is designed to present a clearer, more practical look at OS concepts, techniques, and methods without sacrificing the theoretical rigor that is necessary at this level. It is an ideal choice for those interested in gaining comprehensive, hands-on experience using the modern techniques and methods necessary for working with these complex systems. Every new printed copy is accompanied with a CD-ROM containing simulations (eBook version does not include CD-ROM). New material added to the Second Edition: - Chapter 11 (Security) has been revised to include the most up-to-date information - Chapter 12 (Firewalls and Network Security) has been updated to include material on middleware that allows applications on separate machines to communicate (e.g. RMI, COM+, and Object Broker) - Includes a new chapter dedicated to Virtual Machines - Provides introductions to various types of scams - Updated to include information on Windows 7 and Mac OS X throughout the text - Contains new material on basic hardware architecture that operating systems depend on - Includes new material on handling multi-core CPUs Instructor Resources: -Answers to the end of chapter questions -PowerPoint Lecture Outlines

Examines the workings of an operating system, which is essentially a concurrent programme, and strikes a fine balance between theory and practice. It provides the programme design illustration and guidance along with new concepts, nd ptrsents an in-depth analysis of the fundamental concepts of an OS as an interrupt driven programme whose basic constituents are the processes giving rise to a concurrent programme.

Principles of Operating Systems is an in-depth look at the internals of operating systems. It includes chapters on general principles of process management, memory management, I/O device management, and file systems. Each major topic area also includes a chapter surveying the approach taken by nine examples of operating systems. Setting this book apart are chapters that examine in detail selections of the source code for the Inferno operating system and the Linux operating system.
