Teaching Operating Systems with Linux

Operating systems can feel abstract until students see how the pieces show up in a working environment. Linux gives students a concrete surface for exploring processes, memory, scheduling, filesystems, permissions, and system calls.

I like teaching systems through workflows students can touch. A command-line trace, a small C program, or a broken permission setting can open a larger conversation about how the OS manages resources and enforces boundaries.

The goal is not only to memorize concepts. It is to build the confidence to investigate what a system is doing and explain why.
