Hi!!
Simple answer to a simple question:
URL is an acronym for "Uniform Resource Locator", and it is the
address that specifies the location of a resource on the Internet. A
typical URL must specify the protocol used to access the resource, the
name of the host computer on which it is located, and the path of the
resource:
http://www.server.com/main/folder/resource.html
The above URL indicates that the document resource.html is located at
the web server www.server.com where it can be found in the path
/main/folder.
For example ://www.google.com and ftp://ftp.mozilla.org/pub are
both URLs that indicates the address of two different resources on the
Internet.
An Hyperlink, or simply a Link, is "An element in an electronic
document that links to another place in the same document or to an
entirely different document. Typically, you click on the hyperlink to
follow the link. Hyperlinks are the most essential ingredient of all
hypertext systems, including the World Wide Web."

In HTML documents such links are sometimes called hot-links because
they take you to other document when you click on them. They are
related to the URLs because the URL of the referenced resource is
embedded in the hyperlink.
Here is an example of an hyperlink in an HTML document, you can see
the URL of the document resource.html embedded into it:
<A HREF="http://www.server.com/main/folder/resource.html">Access the Resource</A>
When you see the HTML document with a Web browser, the information
between angle brackets is not displayed, but the text "Access the
Resource" are displayed in whatever format is defined for links by the
browser or the document's author. When you click on the text "Access
the Resource" the document resource.html is displayed, it was reached
following the URL reference embedded in the hyperlink.
So you can easily differentiate URLs from Links by knowing that the
URL is a necessary information that must be embedded into a Link in
order to make the link functional to its purpose, that is to reach the
desired resource. The Link is the way you use to reach the resource.
Note that what you type in a browser's address box to visit a page is
an URL, and the text "Google Answers Terms of Service" at the bottom
of this page is a link to the document termsofservice.html, and the
URL of this document is
http://answers.google.com/answers/termsofservice.html; the same is
valid to the Google Answers' logo image on the top of this page, it is
a link to the page which URL is http://answers.google.com/answers/ .
The confusion comes sometimes from the fact that some Links are
displayed not with an indirect description of the target resource but
with its URL, see for example the links to the pages that I will give
you as further reference:
"What is URL? - A Word Definition From the Webopedia Computer Dictionary":
http://www.webopedia.com/TERM/U/URL.html
"Uniform Resource Locator - Wikipedia, the free encyclopedia":
http://en.wikipedia.org/wiki/Url
"Hyperlink - Wikipedia, the free encyclopedia":
http://en.wikipedia.org/wiki/Hyperlink
In the above case the visible text
"http://en.wikipedia.org/wiki/Hyperlink" is a link to the resource
which URL is http://en.wikipedia.org/wiki/Hyperlink. The embedded URL
is invisible, but it is usually displayed at the Browser's Status bar
at the bottom of their windows when you place the mouse cursor over
the link.
See also the following search result pages, I used the Google
"define:" operator to find definitions:
define:link
://www.google.com/search?num=30&hl=en&lr=&c2coff=1&q=define%3Alink
define:URL
://www.google.com/search?num=30&hl=en&lr=&c2coff=1&oi=defmore&defl=en&q=define:URL
Search strategy:
define:URL
define:link
url
link hyperlink
I hope that this helps you. Feel free to request for a clarification
if you need it or if you find that this anser is incomplete in some
way. I will be glad to give you further assistance on this question.
