A URL (Uniform Resource Locator) is a description of a resource on the Internet. Here is an absolute URL:

protocol://host.domain[:port]/path/filename

where protocol is one of:

You can also use a mailto protocol:

mailto:president@whitehouse.gov

The :port is generally omitted, because each protocol has its own default port number.  However, it is sometimes required when a server is using an non-standard port number.

Here's a typical example:

http://www.ncsa.uiuc.edu/General/Internet/WWW/HTMLPrimer.html

Another form of URL is a relative URL. For example:

data/planets.dat

which is relative to some other URL.
