This Linux Tutorial focuses on the boot process, kernel, system calls, and init implementations, which are the key to understanding any operating system. We take a sneak peek into how Linux actually works internally, resulting in getting better at computer science in general. Do watch the video till the very end to see all the demonstrations. Below are the topics covered in this tutorial: 1. Boot Process 2. Kernel 3. Privilege Levels & Protection Rings 4. System Calls 5. System V Init Implementation 6. Upstart Init Implementation 7. Systemd Init Implementation This video is a part of Web Development Bootcamp and the Linux Masterclass, for beginners to skill up and become comfortable with advanced Linux with a series of videos. It is intended to get you started with various command-line tools and a hands-on approach with examples for Linux Administration. Including concepts of Bash Programming, Linux Kernel, File Systems, Bootloaders, Processes, Devices, and much more.
