There is technically not a do follow link since all links may be followed by a search engine. However, the absence of the attribute "rel='nofollow'" in the HTML hyperlink tag could count as a do follow link.
When a web page makes a link, it transfers page rank to the page it's linking to. That's why it makes sense from a web developer's perspective to have many links pointing to your page but few links on your site pointing to other websites.
However, you can still link to other websites and not lose page rank yourself by including the nofollow attribute. See the reference for more details.
