A URL is a Uniform Resource Locator. Think
of it as a networked extension of the standard filename
concept: not only can you point to a file in a directory,
but that file and that directory can exist on any
machine on the network, can be served via any of
several different methods, and might not even be
something as simple as a file: URLs can also point
to queries, documents stored deep within databases,
the results of a finger or archie command, or whatever.
When encoding a URL, a character may not be available
on the keyboard. Other times, the character of a
URL might not be usable in contexts where it may
conflict with a reserved character. In either case,
the character can be encoded with a % followed by
its ASCII hexadecimal equivalent code.
A Uniform Resource Locator (URL) is a name for a
resource on the Internet.
A Uniform Resource Locator (URL) has this general
syntax:
scheme:[//host.domain[:port][/path][/filename]][newsgroup][email
address]
....
