This edition one again includes new content that, on the one hand, addresses current developments and, on the other, supports the funda- mental aims of the book. Although the volume grown considerably since the first edition, the aim of this work remains to present the core functionalities of operating systems in a com- pact and easy-to-understand manner, and to develop an understanding of how the computer and its components function together with the operating system. One of the new sections in Chapter 3 includes a detailed description of the boot process of Linux operating systems, with all the relevant steps, from turning on the computer to handing over control to the user. The description of the memory hierarchy in Chapter 4 has been expanded, particularly with regard to the performance parameters of the individual cache levels. Chapter 5 now includes explanation of the translation lookaside buffer, which accelerates the translation from virtual to physical memory addresses. Additionally, for the first time, the chapter contains a description of the slab al- locator, which is used by the Linux operating system kernel to efficiently manage the kernel’s frequently used small objects and other data structures in the main memory.
