bombsaway is fking with you, C & hardcore ASM, maybe some machine code editing if they went that far for some reason, but for internet purposes there might be simple algorithms that deal directly in binary to ensure data consistency (OS' are tough, and the internet has been kiking its ass ever since the beginning of hackers with the internet). OS' are complex and if it were up to any of the jokesters @Apple, Microsoft we'd have no OS'. But Unix was there in the beginning so All OS' tend to branch from it, stealing ideas/approaches to what makes an OS an OS.
