A minor point, but the various entities talk in HTTP (HyperText
Transfer Protocol). HTML is _one_ of the content-types that can be
transported (it's basically a MIME transport protocol.) HTML documents
contains the URLs which Mosaic (or Lynx or Cello, or whatever browser)
"executes" when the user clicks on the associated hot spot.
