Operating System Concepts ReviewThis provides a solid introduction to the basics of operating system (OS) internals. After an introductory section, this covers the major subsystems in an orderly progression: processes, memory, storage, protection, distributed systems, and special purpose systems. Although I might quibble with some of the ordering, (e.g., virtual memory vis a vis process management), this gives a firm foundation for anyone teaching introductory OS internals. As an aside, instructors should also be aware of the additional support they'll find at the book's web site.
I have no real objections to this book, but find that some of its emphasis won't suit all readers. For example, 99% of all processors don't run Windows or Linux. Instead, they run your DVD player, car air bags, microwave, digital watch, and just about everything else with a power cord or battery. Engineering students headed for embedded system development will need supplementary material. Also, like every other undergrad text I know, this underplays the critical importance of standards in everything from APIs and file system structures to network protocols and safe coding guideline.
I've taught from this book and from Tanenbaum and, to tell the truth, have no strong preference between the two. They present comparable material at roughly the same level, both offer good case studies, and both offer on-line support to students and instructors. Each outweighs the other on specific topics but, on the whole, that seems to balance out. I note that some reviewers object to this book's level. To them, I can only say: that's life. OS development is at least ten times as hard as developing mainstream applications (as measured by programmers' output of debugged code), so it will require some programming knowledge to follow discussions of OS internals. Railing against obviously important prerequisites says more about the speaker than about the book.

Open-source operating systems, virtual machines, and clustered computing are among the leading fields of operating systems and networking that are rapidly changing. With substantial revisions and organizational changes, Silberschatz, Galvin, and Gagne's Operating System Concepts, Eighth Edition remains as current and relevant as ever, helping you master the fundamental concepts of operating systems while preparing yourself for today's emerging developments.
As in the past, the text brings you up to speed on core knowledge and skills, including:
What operating systems are, what they do, and how they are designed and constructed
Process, memory, and storage management
Protection and security
Distributed systems
Special-purpose systems

Beyond the basics, the Eight Edition sports substantive revisions and organizational changes that clue you in to such cutting-edge developments as open-source operating systems, multi-core processors, clustered computers, virtual machines, transactional memory, NUMA, Solaris 10 memory management, Sun's ZFS file system, and more. New to this edition is the use of a simulator to dynamically demonstrate several operating system topics.
Best of all, a greatly enhanced WileyPlus, a multitude of new problems and programming exercises, and other enhancements to this edition all work together to prepare you enter the world of operating systems with confidence.

Distributed Operating Systems: Concepts and Design ReviewConcepts and coverage is excellent for learning and the content are not too in-depth especially towards a student. Cover areas like file organisation as well as memory management which is lacking in many similar topic publications. Chapters discussed are comprehensive and relevant to learners in these fields. Diagrams are illustrative and easy to understand. A good choice especially to students that are beginners in operating systems concepts.Distributed Operating Systems: Concepts and Design OverviewDistributed Operating Systems will provide engineers, educators, and researchers with an in-depth understanding of the full range of distributed operating systems components. Each chapter addresses de-facto standards, popular technologies, and design principles applicable to a wide variety of systems. Complete with chapter summaries, end-of-chapter exercises and bibliographies, Distributed Operating Systems concludes with a set of case studies that provide real-world insights into four distributed operating systems.

Operating System Concepts, Seventh Edition ReviewDefinetely targeted towards the sophomore/Junior level students. This book goes into generic concepts used by most operating systems - i.e., what happens when a program is loaded into memory? How do processes make system calls to the kernel, how is deadlock among several programs competing for the same resources resolved, what is the characteristics of real-time operating systems etc.
I have adopted this book for teaching the operating systems course. I find that students, in general, appreciate this book as it is very readable. I believe a good text book should have the following qualities: It should be light enough to read it in bed, the fonts should be large enough to not give a headache after an hour of reading, should be written in clear lucid style with plenty of figures and should have decent binding. I believe this book qualifies in all those aspects.
However, I do have one unpleasant comment. I hate it when authors keep coming out with new editions with just small delta changes - forcing students to buy high priced editions because some professors could care less about the cost of books to students (after all, we profs get them for free). The 7th edition is not a whole lot different than the 6th edition (about 2 or 3 new chapters included in the 7th edition). Considering that you can buy a used 6th edition for half the price of a new 7th edition, I recommended my students to go with the 6th edition instead and chose to just teach them some of the additional materials from the 7th edition.
What I would have liked to see in this book - greater detail (perhaps with some psuedocode) on the workings of the kernel and how programs can take advantage of it (I guess I am thinking along the lines of Steven's UNIX programming book).Operating System Concepts, Seventh Edition OverviewAnother defining moment in the evolution of operating systemsSmall footprint operating systems, such as those driving the handheld devices that the baby dinosaurs are using on the cover, are just one of the cutting-edge applications you'll find in Silberschatz, Galvin, and Gagne's Operating System Concepts, Seventh Edition.By staying current, remaining relevant, and adapting to emerging course needs, this market-leading text has continued to define the operating systems course. This Seventh Edition not only presents the latest and most relevant systems, it also digs deeper to uncover those fundamental concepts that have remained constant throughout the evolution of today's operation systems. With this strong conceptual foundation in place, students can more easily understand the details related to specific systems.New Adaptations* Increased coverage of user perspective in Chapter 1.* Increased coverage of OS design throughout.* A new chapter on real-time and embedded systems (Chapter 19).* A new chapter on multimedia (Chapter 20).* Additional coverage of security and protection.* Additional coverage of distributed programming.* New exercises at the end of each chapter.* New programming exercises and projects at the end of each chapter.* New student-focused pedagogy and a new two-color design to enhance the learning process.
