Control by which operating system? ARC?

Can you reword your question? It doesn't make much sense.

Hey my question is that what some components which control O.S?

Sorry but I still don't understand the question.

What do you mean by the OS? Windows or ARC? What do you mean by components? Windows hardware (graphics cards, sound cards, cameras etc) or EZ-B sensors, servos etc?

operating system are windows 7, vista, linux, MAC OS.

I think the question is what are the four hardwares control by the ARC platforms? If so EZ-B is pretty much the Brain of your robots, it can control everything from the wheelbase to scripting for autonomous behaviours.
