Step-by-step explanation:
A prototype is an early sample, model, or release of a product that is built to test a concept or a process. It is a trial working model of a design that is built to test design decisions and identify potential problems. Prototypes are used to evaluate designs and discover flaws and weaknesses. For example, when developing a detailed design for a vehicle, the design team may initially create a prototype of the electrical system and then later implement a comprehensive prototype of the whole vehicle.
