I like using #FreeDOS to explain how a computer starts up. DOS is simple enough and small enough that you can see the moving parts.

And once you see how it works in DOS, you can understand more complex systems like #Linux

Start by learning a simple system and work your way up from there.

I started when Digital Research and Microsoft were still vying for the market equally. DR DOS or MS DOS.

To this day I still use CLI skills learned during that period, including how every Byte of memory was sacred.

When Win95 came along things just started going downhill, and haven't really changed course to my mind.
