I'm learning HTML at www.w3schools.com/html/html_urlencode.asp and don't understand this sentence:

host - defines the domain host (default host for http is www)




    scheme - defines the type of Internet service (most common is http)
    host - defines the domain host (default host for http is www)
    domain - defines the Internet domain name (w3schools.com)
    port - defines the port number at the host (default for http is 80)
    path - defines a path at the server (If omitted: the root directory of the site)
    filename - defines the name of a document or resource

What is the relation between "domain host" and "www"?

  • Opinion: You should not use or link to w3schools. It's not a reliable source of information and we don't want to encourage its use.

The domain = w3schools.com

www is the host.
The path is /html/ And the file is html_urlencode.asp

    Actually www is the hostname, w3schools.com is the domain. Hostname is a single word inside a (sub)domain. Sep 26, 2014 at 15:32
