For me, it's the concept of how computers actually work under the hood that I want my kids to have a grasp on. It's all files in a file system, and they all do different things. And that's different than what might be going on when you load a website, though it's all (sorta) files on the other end of that as well.

Files have metadata that describes to the operating system what they are for, and how they are to be used.

Etc, etc.

This is information that I think will be very enlightening for them, even though not strictly required to operate a computer these days.
