Kernel Interactive Lessons

1Overview of the KernelLearn how the Linux kernel mediates hardware, resources, isolation, and user-space requests.
2Privilege LevelsLearn how processor privilege separates user execution from trusted kernel execution.
3System CallsLearn how user-space code invokes Linux kernel services and how to inspect calls safely with `strace`.
4Kernel InstallationLearn how to install, boot, verify, and retain a distribution kernel with a tested fallback.
5Kernel LocationLearn where distributions place kernel images, initramfs files, configuration, symbols, and versioned modules.
6Kernel ModulesLearn how to inspect, load, configure, and safely remove release-specific Linux kernel modules.

Frequently Asked Questions

What does the Linux kernel do?

The kernel manages hardware, memory, processes, and access to system resources while providing system calls that programs use to request services.

Will I learn about kernel modules?

Yes. The course explains how modules extend the kernel and introduces tools such as lsmod and modprobe for inspecting and managing them.

Do I need to compile a kernel?

No. The course focuses on kernel concepts, locations, versions, installation, modules, privilege levels, and system calls rather than requiring a custom build.
