A graphic tablet is a computer input device. It is used to draw images and sketches on the tablet screen with a special pen as you draw with a pencil on the paper.
A graphics tablet, often known as a drawing tablet or a pen tablet, is a natural input device that translates information from a portable stylus. The stylus is used like a pen, pencil, or paintbrush, with the tip pressed on the tablet's surface.
I haven't worked much with graphic design but usually when I want to make a sketch or rough design I just quickly draw something out. I wonder how close to that experience these tablets can provide.
