Now that you’ve made important decisions about how to install Linux on your system, you need to learn more about the Linux kernel to make important tuning decisions. We’ll discuss how Linux evolved and then delve into its architecture. We’ll include information on how the kernel is organized, what its responsibilities are, and how memory management is handled. We’ll discuss process management and interprocess communication, followed by an overview of the Linux Symmetrical Multiprocessing Model. Finally, we’ll examine the Linux file systems.
