The Free On-line Dictionary of Computing (30 December 2018):

web page

    A block of data available on the World-Wide
   Web, identified by a URL.  In the simplest, most common
   case, a web page is a file written in HTML, stored on the
   server.  It may refer to images which appear as part of
   the page when it is displayed by a web browser.  It is also
   possible for the server to generate pages dynamically in
   response to a request, e.g. using a CGI script.

   A web page can be in any format that the browser or a helper
   application can display.  The format is transmitted as part
   of the headers of the response as a MIME type,
   e.g. "text/html", "image/gif".

   An HTML web page will typically refer to other web pages and
   Internet resources by including hypertext links.

   A website often has a home page (usually just the
   hostname, e.g. http://foldoc.org/).  It may also have
   individual home pages for each user with an account at the
   site.
