Acerca del autor

Abraham Silberschatz is the Sidney J. Weinberg Professor of Computer Science at Yale University. Prior to joining Yale, he was the Vice President of the Information Sciences Research Center at Bell Laboratories. Prior to that, he held a chaired professorship in the Department of Computer Sciences at the University of Texas at Austin. His research interests include database systems, operating systems, storage systems, and network management.

Professor Silberschatz is a Fellow of the Association of Computing Machinery (ACM), a Fellow of Institute of Electrical and Electronic Engineers (IEEE), a Fellow of the American Association for the Advancement of Science (AAAS), and a member of the Connecticut Academy of Science and Engineering. He received the 2002 IEEE Taylor L. Booth Education Award, the 1998 ACM Karl V. Karlstrom Outstanding Educator Award, and the 1997 ACM SIGMOD Contribution Award. In recognition of his outstanding level of innovation and technical excellence, he was awarded the Bell Laboratories President's Award for three different Projects ?? the QTM Project (1998), the DataBlitz Project (1999), and the NetInventory Project (2004).

Professor Silberschatz' writings have appeared in numerous ACM and IEEE publications and other professional conferences and journals. He is a coauthor of the textbook Database System Concepts. He has also written Op-Ed articles for the New York Times, the Boston Globe, and the Hartford Courant, among others.

Peter Baer Galvin is the chief solutions architect for Pluribus Networks (www.pluribusnetworks.com). Previously he was the CTO for the systems integrator Corporate Technologies, and a lecturer at Boston University. He has also been a columnist for ;login:, SunWorld, and SysAdmin magazines, and has written articles for Byte and other magazines. Mr. Galvin blogs for anewdomain.net and byte.com. As a consultant and trainer, he has given talks and tutorials on security and system administration worldwide.

Greg Gagne is chair of the Computer Science department at Westminster College in Salt Lake City where he has been teaching since 1990. In addition to teaching operating systems, he also teaches computer networks, parallel programming, and software engineering. He has made presentations at educational conferences and also provides workshops to industry professionals. Professor Gagne was the recipient of the Shaw Faculty Publication Prize in 2007.

STAY CURRENT WITH THE EVER-CHANGING FIELD OF OPERATING SYSTEMS!

This new Ninth Edition of Silberschatz, Galvin, and Gagne's Operating System Concepts introduces the fundamental concepts of the field as well as cutting edge developments to give students a broad understanding of the fast-developing world of operating systems.

Changes in the new edition were guided by recent growth in three key areas that have affected operating systems: multicore systems, mobile computing, and virtualization. Relevant coverage of these topics has been integrated throughout this new edition, or in the case of virtualization, comprises an entirely new chapter. Additionally, nearly every chapter has been updated with new material and older material has been removed.

New to this edition:

• Substantive organizational changes including:

- Real-time systems integrated as appropriate throughout the text instead of concentrated in a single chapter.
- Re-ordered chapters on storage management.
- Presentation of process synchronization now appears before process scheduling.

• New Chapter 16, Virtual Machines, provides an overview of virtualization and how it relates to contemporary operating systems.
• New Chapter 17, Distributed Systems, combines a selection of materials from previous Chapters 16, 17, and 18.
• The Linux Systems chapter has been updated to cover the Linux Kernel version 3.0
• A new Linux virtual machine including Linux source code is provided on the supporting web site. This virtual machine also includes a development environment with compilers and editors. Most of the programming assignments can be completed using this virtual machine.
• Over 60 new written exercises and over 20 new programming problems and projects, most involving processes, threads, process synchronization, and memory management. Some involve adding kernel modules to the Linux system.

The Ninth Edition of this respected text continues to present students with real-world operating systems to illustrate fundamental operating concepts. Students are able to bridge the gap between concepts and actual implementations by learning a solid theoretical foundation of operating systems.
