I recently had the opportunity to dive deep into the inner workings of Linux by reading the book “How Linux Works” by No Starch Press. As someone who has always been fascinated by the world of operating systems, this book provided me with a comprehensive understanding of how Linux operates and the underlying principles that make it such a powerful and versatile system.

One of my favorite sections of the book was the chapter on processes and threads. Ward goes into great detail about how Linux manages and schedules processes, explaining concepts like process IDs, process trees, and the role of the scheduler. This section gave me a newfound appreciation for the efficiency and scalability of Linux, as well as a deeper understanding of how multitasking works in the system.

Another highlight of “How Linux Works” is the chapter on the kernel. Ward provides an in-depth exploration of the Linux kernel, from its architecture to the various subsystems that make up the heart of the operating system. This section helped me grasp the importance of the kernel in managing hardware resources, handling system calls, and enforcing security policies. It was fascinating to learn how each component of the kernel contributes to the overall functioning of Linux.

In addition to the technical content, “How Linux Works” also includes practical examples and exercises that help reinforce the concepts discussed in each chapter. This hands-on approach was incredibly beneficial in solidifying my understanding of Linux and allowed me to apply what I learned to real-world scenarios.

Overall, I found “How Linux Works” to be an invaluable resource for anyone looking to gain a deep understanding of Linux.
