It uses tubes and relays, which are discrete digital components (they're either on or off, with no states in between). An analog computer as I understand it is something like a differential analyser, which uses rollers and turntables which have (virtually) infinite states, depending on how finely you can measure. Another example of an analog device would be a slide rule. Regards, Mark.
