The 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. To make the sharing of a computer tolerable, an operating system must enforce certain rules of behavior on all its users. One would therefore expect the designers of operating systems to do their utmost to make them as simple, efficient, and reliable as possible. A number of operating systems made in the early 1960's had these characteristics; but in the late 1960's designers were often overambitious and built enormous systems with poor performance. I see no inherent reason why operating systems should not reach the quality of program construction found in present compilers; this will require an understanding of the principles common to all operating systems and a consistent use of safe methods of designing large programs. It is my hope that this book will give you a start in this direction. I assume that you are familiar with the basic structure of computers and programming languages and have some experience in writing and testing non-trivial programs. In a few cases a knowledge of elementary calculus and probability theory is also needed. THEM

Operating Systems: Internals and Design Principles provides a comprehensive and unified introduction to operating systems topics. Stallings emphasizes both design issues and fundamental principles in contemporary systems and gives readers a solid understanding of the key structures and mechanisms of operating systems. He discusses design trade-offs and the practical decisions affecting design, performance and security. The book illustrates and reinforces design concepts and ties them to real-world design choices through the use of case studies in UNIX and Windows.
