A url is usually in the format http://www.blank.com or http://www.blankschool.edu.au/pathname/. or http://www.trinity.wa.edu.au/plduffyrc/issues/young.htm. Each part of the url is like a mailing address, it points to a particular computer in a particular organisation in a particular place.The part of the URL before :// represents the protocol, scheme, or format used to retrieve the document. http://
http://=means the document is on the WWW (world wide web). Hyper Text Markup Language or html is the authoring language used to create documents.
