A prototype is a first model or example of a machine or other product upon which all later forms are developed. For example, a car maker might make a prototype of a car and test it before releasing a final model for sale. Ex: I'm testing a prototype for safety and speed. After, we will ready for product launch. Ex: This is just a prototype, so the final version will be different.
