The first two chapters (Concepts and Tools, and System Architecture) lay the foundation with terms and concepts used throughout the rest of the book. The next three chapters—System Mechanisms, Startup and Shutdown, and Management Mechanisms—describe key underlying mechanisms in the system. The remaining chapters—Processes, Threads, and Jobs; Memory Management; Security; I/O System; Storage Management; Cache Manager; File Systems; and Networking—explain the core components of the Windows 2000 operating system.
