I have changed the last answer of this quiz "To publish a document at the same address independent of the computer and directory it is stored on." into false, because the URL is not an address of a file that exists independently from the computer it resides on. Indeed, if you copy and republish a file on your own Web server, it will have a different address and cannot be found with the old address if the older file is deleted. --SteffenStaab (discusscontribs) 20:22, 6 November 2013 (UTC)

I agree with your example but URLs are also used to request the same content independently on which machine it is stored (think of large scale web applications and load balancing) also you can move servers and domains and still URLs should not change and still be accessible. --Renepick (discusscontribs) 20:34, 6 November 2013 (UTC)
The URL is really tightly connected to the domain name, which refers to one (or few) servers. There are schemes, such as , that abstract completely from the server on which a file is hosted. But, this is different from URLs.
