This book explains the fundamental concepts of operating systems in a clear, detailed and easy way. It also considers some existing operating systems such as UNIX to expalin how these concepts are implemented. While reading this book, you feel as if an experienced teacher is in front of you and explaining the things to you! I have never seen such a good book on this subject earlier.

The only problem with this book is it is slightly old. As a result, you don't find some advanced stuff.

The author's style in writing of this difficult (but fascinating) subject, is informative and surprisingly understandable. This ought to be the book with the best pdeagogic approach to teaching the theory and implementation of operating environments. Sll aspects of this particular type of software are explained clearly and smoothly. The author presents some very advanced topic nevertheless, but the beginner is given a path to arrive to them, and not be scared.

It is very good that the operating systems (further in this review: OS) taken as examples are widely ranging from single-suer, single-task, to much more complex mainframe OS such as VMS. I won't list them all, suffice to say that a very broad range of OSs are covered, and in a very pertinent and interesting way.

The code examples in the book are in Pascal, which some may think of as a weakness, but in reality it is a great advantage: Pascal code reads very much like normal English language and it's therefore easy to understand and follow, and expecially, easy to re-implement in your programming language of choice. I am a C programmer myself, and yet the examples have not put me off in any way. So if you ever thought of implementing an OS in Forth, C or any other programming language, know that this book will not hinder you but help you.

My final word is that the price at which this book can be bought (usually second hand, but sometimes also new) does no justice to it. This is not a $10 book, rather a $100 book that is greatly overlooked.
