An anchor tag is generally used to link to a location in your page, a page in your website or another page on the web. Anchor tags can also be used create a link point in your page, alert mobiles to a phone number and open a blank email. I'm sure there might be a few more I can't think of at this hour.

<!-- General use: -->
<a href="#top"></a>
<a href="about.html"></a>
<a href="http://www.google.com"></a>

<!-- Other uses -->
<a name="jump_here"></a>
<a href="tel:5555 1234">5555 1234</a>
<a href="mailto:me@here.com">me@here.com</a>

The click function you are referring to above is jquery's way of adding a click function to an anchor or many anchors. This is similar to:

<a href="#" onclick="alert('hey there!');return false;">Hey!</a>
<!--
If you don't put in the 'return false;' the href='#' will
be called after the alert!
Note: If you leave the 'href' off, then you won't get
the hand when hovering.
-->

Hope this helps. :)
