I dont know, i just don't like the tone. This is a complex subject where the target audience should probably already know what is an hexadecimal number or an interrupt and the explanation of a cpu register ought to be better than:
"A register is a tiny slot inside the CPU. It holds a number the CPU is using right now."
If the subject interest you, you deserve better.
There's nothing wrong with it but most people striving to do this would make each bit clickable to detail or something so that you can read at your level. I imagine this was a constraint of the site framework or the author's writing style.
But hey what the heck, it's fine. An LLM can rewrite it to whatever level of knowledge you like so the deepest level is optimal.
I wonder if anyone will actually write their own article/blog providing a much better explanation of the subject matter. Or at least provide links to those articles that are alternatives to this.
