I think conciousness is having your i/o ports open.

Funny you should mention that. I/O seems to me to have quite a lot to do with the difference (if there is one) between a script and some other program that is not a script. I tend to think of a script as involving a minimum of user interaction (or none). It can ask the user questions and still be a script, but when you start getting into the realm of pulldown menus and key shortcuts and stuff, is it still a script, even though its actions are determined dynamically rather than being scripted? I tend to think of it more as an application at that point.

Consciousness, of course, is an operating system, because it's what makes it possible for you to carry out any other mental activity, and any mental activity you carry out is within the bounds of your consciousness.
