An overhead projector is used to project an image of a transparency onto a wall or screen by means of an overhead mirror.
There are also "slide projectors" that are used to display photographic slides on a wall or screen.
A "projector" or "digital projector" would be used similar to a computer monitor or a television screen that would display an inputted image from a variety of sources (blu-ray player, computer, laptop, dvd players, game console, etc.). In the case of a projector the image is projected with the help of a light apparatus shining through a small silicon ship and projected through a lens to create an image on your wall or projector screen.
