True, except that is a real memory limit. Virtual memory could be much greater than that. Like phone numbers. We need 10 digit dialing in the USA but that is 10 trillion phone numbers. We don't have near that many phones in the USA, but 10 digits makes management of numbers easier. Same for virtual memory.
