A Uniform Resource Locator (URL
) is a string of characters conforming to a standardized format, which refers to a resource on the Internet (such as a document or an image) by its location. For example, the URL of this page is http://www.freesmileys.org/free-smileys-glossary.php
An HTTP URL, commonly called a web address, is usually shown in the address bar
of web browser

where you can type a url of the site you want to visit, many web browsers also have a Favourites drop down menu (Internet Explorer
) or Bookmarks (FireFox
) that allow you to bookmark or store favourite website locations in a single handy place that is easy to retrieve, instead of remembering every web address you go to.

websites on the internet. Web browsers
have now been installed on some phones (cell phones) allowing people to browse
certain websites on the internet via their mobile device.
There are many web browsers available for the pc, two very common ones are FireFox

, it's own, and the settings of a website reflect this, allowing only itself to use it's own resources such as images and downloads.
But sometimes, it is neccessary or convenient to allow other websites to link to another websites resources. This is called hotlinking
. A website hotlinking
to another image (etc) does not use any of it's own bandwidth
limit, it's ability to hotlink
to another websites resource is only limited by the other websites bandwidth
limit. Needless to say if enough people hotlink
to a file, it has the ability to shut down a site to which the file being used is owned and is hotlinked
, though abundant it seems, is nonetheless limited on the net, almost all sites have a bandwidth limit
of some sort and when the bandwidth
limit is reached, the offending site is shut down by the host
or expensive charges are charged to the owner of the shut down site for the host to continue running it.
