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"?
