Everything runs its own version of instructions. I'm pretty sure the more common name is drivers. I'm surprised at how complex the instructions can get. I'd hate to be the person writing memory addresses into a bunch of computer chips. It is so easy to get distracted by the flashy display, and not realize what goes on beneath the surface. All of them are definitely unique. Imagine how hard it'd be if we didn't have a compiler or interepreter so we can write instructions in a human readable format. It's definitely not impossible. We would spend forever getting memory addresses right though.
