What is a URL?
Internet Marketing Dictionary | URL
A URL is simply the address of a web page and can be
entered into the address bar of your browser when you want to
see the underlying page.
When you enter a URL or click on a link, your browser essentially goes out
to the internet to find the file that corresponds to that
URL's address and fetches a copy of it for display. The file
itself will then be interpreted by your browser software
(Firefox, Safari, Operal Internet Explorer etc.) so that you
see the web page in the way the designer intended.
A URL does not need to point just to a web page though. It
can point directly to a pdf file, or a music file or video. Or
even a text, Word or Excel document. So if you want to
make a Word document available on the internet all you need to
do is upload it to your server. Once you've done that, anyone
clicking on a link to that file or just entering it into the
address bar of their browser will be able to download it.
One problem with URLs is that people move files around from
time to time and delete them too which means that quite
often the file you are looking for doesn't exist
anymore or has been moved. This typically generates a
404 error page which is
essentially a message that tells you that the file you want
can't be found.
