      Modern USB keyboards need to be asked what’s being pressed by the CPU multiple times a second, but old PS/2 keyboards will actually interrupt the CPU to send the key press command

        Oh, didn’t actually know what’s being done behind the scene…

        Why is this relevant to Linux only?

        Why e in this context? I have seen sei() and cli() before, but not E.

          That’s the very important information you got from the keyboard.

          Some context may come later, but it will take ages.

            Thanks, apparently I can’t read. I somehow missed the top right yellow speech bubble.
