You are correct, the browser doesn't communicate directly with the root
servers, but as Tim mentions, it is done on the browser's behalf until
ultimately the browser gets its answer.

My question then is this: Does splitting that particular hair of the
name resolution mechanics do more to clarify things for Peter, who had
some initial difficulty grasping localhost, registrar, and hosting
company, or does it serve more as an opportunity to show how smart you
think you are?
