Revised and updated with a new chapter on virtualization, this entry level undergraduate textbook for computer science, information technology, and electrical engineering students provides an overview of the fundamentals of operating system design and construction. Beginning with an overview of general principles, the volume covers processes and threads, processor scheduling and synchronization principles, file management, I/O systems, memory management, security, and networking, and a series of appendices discuss modeling and testing using Linux and Java platforms. Chapters include numerous illustrations, code examples, and practice exercises, and an accompanying CD-ROM provides simulation models and additional tutorials.
