The basic addressing scheme for the World Wide Web is the
Universal Resource Identifier or
URI. For example, the URI of the
New Mexico Tech homepage is “
In general, a URI has as many as four parts:
The method name describes the general protocol for
retrieving resources. Most Web pages use method
http, which stands for HyperText
Transfer Protocol. There are many others, such as
ftp: for File Transfer Protocol.
This portion describes a
specific host machine. For example,
www.nmt.edu is a specific processor that
serves Web pages.
Describes a specific document on the host machine.
Refers to a specific location in the document. If
there is no “
the URI refers to the beginning of the document.
In an XHTML document, a fragment identifier refers
to the element that has that
attribute. For example, if a document contained
this paragraph, the fragment identifier
<p id='mongooses'> The plural of "mongoose" is "mongooses," not "mongeese." The word is Hindic in origin, so it does not follow the rule for "goose." </p>
