Introduction to Operating Systems

This is a book about modern operating systems. The whole book revolves around the three main concepts of virtualization, concurrency and persistence, and introduces the main components of all modern systems (including scheduling, virtual memory management, disk and I/O subsystems, and file systems). This book has a total of 50 chapters, divided into 3 parts, covering virtualization, concurrency and persistence. Most of the chapters in this book begin with a specific problem and then solve it using techniques, algorithms, and ideas introduced in the book. The author introduces the topic concepts introduced in the form of dialogue, and the writing is humorous but penetrating, striving to help readers understand the principles of virtualization, concurrency, and persistence in operating systems. The content of this book provides real executable code (not pseudo-code), and also provides corresponding exercises, which is suitable for teaching by relevant professional teachers in colleges and universities and self-study by college students.
