Operating system design

About this book

"Lauded for avoiding the typical vague, high-level survey approach found in many texts, earlier editions of this bestselling book removed the mystery by explaining the internal structure of an operating system in clear, readable prose. The third edition of Operating System Design expands and extends the text to include new chapters on a pipe mechanism, multicore operating systems, and considerations of operating systems being used in unexpected ways. The text covers all major operating system components, including the key topics of scheduling and context switching, physical and virtual memory management, file systems, device drivers, device-independent I/O, Internet communication, and user interfaces. More important, the book follows a logical architecture that places each component in a multi-level hierarchy. It simplifies learning about operating systems by allowing a reader to understand one level at a time without needing forward references. It starts with a bare machine and builds the system level by level. In the end, a reader will appreciate how all the components of an operating system work together to form a unified, integrated platform that allows arbitrary application programs to run concurrently. The text uses a small, example system named Xinu to illustrate the concepts and principles and make the discussion concrete. Because an operating system must deal with the underlying hardware, the text shows examples for the two basic computer architectural approaches used in the computer industry: CISC and RISC. Readers will see that most of the code remains identical …
