Modern Operating Systems 3rd Edition, Tanenbaum


Modern Operating Systems 3rd Edition PDF Download Ebook. Andrew S. Tanenbaum incorporates the latest developments in operating systems technologies. The book includes up-to-date materials on relevant operating systems such as Linux, Windows, and embedded real-time and multimedia systems.

This text includes new and updated coverage of multimedia operating systems, multiprocessors, virtual machines, and antivirus software. It covers internal workings of Windows Vista (Ch. 11); unique even for current publications by providing information on current research based Tanenbaum’s experiences as an operating systems researcher.

This book focuses on traditional operating systems concepts: processes, deadlocks, memory management, I/O, and file systems. There is nothing groundbreaking in these early chapters, but all topics are well covered, each including sections on current research and a set of student problems. It is enlightening to read Tanenbaum's explanations of the design decisions made by past operating systems gurus, including his view that additional research on the problem of deadlocks is impractical except for "keeping otherwise unemployed graph theorists off the streets.

It is the second half of the book that differentiates itself from older operating systems texts. Here, each chapter describes an element of what constitutes a modern operating system--awareness of multimedia applications, multiple processors, computer networks, and a high level of security. The chapter on multimedia functionality focuses on such features as handling massive files and providing video-on-demand.

Included in the discussion on multiprocessor platforms are clustered computers and distributed computing. Finally, the importance of security is discussed--a lively enumeration of the scores of ways operating systems can be vulnerable to attack, from password security to computer viruses and Internet worms.

Included at the end of the book are case studies of two popular operating systems: Unix/Linux and Windows 2000. There is a bias toward the Unix/Linux approach, not surprising given the author's experience and academic bent, but this bias does not detract from Tanenbaum's analysis. Both operating systems are dissected, describing how each implements processes, file systems, memory management, and other operating system fundamentals.
