No. For a start, URLs are not only used for Web sites, but also for FTP sites and others.
But not even all Web sites start with "www"; many have another prefix, or none at all. The use of "www" is just a convention, that is often followed.
Look at WikiAnswers for a counterexample - the full URL is http://wiki.answers.com. "http://" is the protocol; but this is not followed by the common "www".
www and com are parts of a URL. these conventions are used in ALL languages, including Hebrew.
