An Introduction to Operating Systems

This text aims to to provide a firm foundation in the principles and concepts of operating systems design and discuss major issues, as well as to show how several operating systems have implemented theses concepts. It covers all major topics of operating systems, including memory management, I/O processing, concurrent processing, auxiliary storage management, and scheduling. There is also a chapter on queuing theory and a chapter with four case studies: MS-DOS, UNIX, VMS, and MVS. Additional case studies are presented at the end of each chapter. Features: Describes what an operating system does, how it may do it, and why there are different approaches. Features 2 types of case studies: the first gives an overview of a particular operating system and how it has implemented some of the important topics covered in the text; second provides a discussion of how an operating system deals with one specific topic. Includes an operating systems simulation project in the appendix.
