Comics deal with two fundamental communicating devices: words and images. Admittedly this is an arbitrary separation. But, since in the modern world of communication they are treated as independent disciplines, it seems valid. Actually, the are derivatives of a single origin and in the skillful employment of words and images lies the expressive potential of the medium.
