WireframeA flat visualization of a user interface that depicts only structure. This is typically a bunch of empty shapes with labels that show the positions and relative sizes of things. Technically speaking, a wireframe isn't a mockup because a mockup depicts exactly how the end-product will look while a wireframe only gives you a rough idea of how it will look.
PictureA hand drawn or digital image may be used as a mockup for a two dimensional work product such as a user interface.
Hardcoded User InterfaceA user interface that looks and acts much like the final product but with hardcoded data and functionality. For example, a banking mobile app that looks like the final product but doesn't show data from a database or perform transactions.
Paper PrototypePaper crafts that represent two or three dimensional work products. For example, a strip of paper that represents a sequence of screens in a mobile app.
Full Size ModelA physical model may be crafted with inexpensive materials at full size. For example, a snowboard mockup may look exactly like the finished product but be crafted from a softwood such that it is lighter and far less durable than the finished product.
Scale ModelA model that is accurately constructed at a smaller scale than the finished product. Relative sizes of parts are controlled to be the same as the final product. For example, a model of a train station design complete with buildings, landscapes and infrastructure at 1:40 scale.design. For example, a 3d model of a chair that can be used to compare design alternatives.
AnimationA moving picture such as an animated gif or a full animation of a work product. For example, an architectural firm that visualizes projects for clients with an animation that explores the exterior and interior of a building.
SimulationsMockups can have a game-like interface whereby users can interact and explore. For example, a digital model of a building that you can navigate at human scale like a character in a video game. prototype is a functional or semi-functional early stage work product that is used for demonstration and feasibility analysis. For example, an experimental solar panel module that actually generates power. Unlike a mockup, a prototype is potentially an expensive item such as an evolutionary prototype of an advanced technology. Inexpensive prototypes are known as throwaway prototypes.
An inexpensive representation of the look and feel of a user interface, product, service, component, part, building or physical environment.
