Media in art is a term which describes either a type of art or the material used by the artists to create the work piece. Drawing media can either be dry or use a fluid solvent .Dry drawing media include charcoal, graphite, silver point and pastel. Drawing media that use fluid solvent are pen, ink and marker.
Ummm, I think you wanted to add options but something that could be used to help clarify is rereading or finding words that you dont understand and search them in a dictionary.
The sensor: The most obvious difference between film and digital is the sensor used to take the photo. With film cameras a film sensitive to light is placed behind the lens. When a photo is taken the shutter opens for a predetermined period of time and light hits the film. The result is a photo "printed" on the film.
