Short answer: It depends. Long answer: In my experience, prototype is used very loosely and can mean many things. But the point is that a prototype is not a fully functioning app/system/software yet. It is used to demonstrate the possible features/functionalities that the app would/could have. How you demontrate it depends on the specific case. Some prototypes can be created using a simple word/powerpoint slide, some can be created using mockup screens/wireframes and some are semi-functioning products. I do not think there is one single answer to this.
