Can a Graphic Card have a Digital user interface (DVI)?

I have this Desktop it’s an Hp pavilion HPE H8t series. It has a 1 GB DDR Ram with a Radeon HD 6670 Graphics Card. All I wanted to know is whether the Graphic Card could have a Digital user interface (DVI) so that I could use it on my Monitor, Because my Monitor Has a DVI –D connection and I want to have a digital kind of connection with it, what do I need to use so that I can link that up ?
