Inside each of these parts are thousands to trilli<answer>on</answer>s of small electrical circuits which can be turned off or <answer>on</answer> by means of an electr<answer>on</answer>ic switch. Each circuit represents a bit (binary digit) of informati<answer>on</answer> so that when the circuit is <answer>on</answer> it represents a "1", and when off it represents a "0" (in positive logic representati<answer>on</answer>). The circuits are arranged in logic gates so that <answer>on</answer>e or more of the circuits may c<answer>on</answer>trol the state of <answer>on</answer>e or more of the other circuits.
In positive logic representation a "1" represents when a circuit is what?
