Ais a simplified representation of a real object or system.

Models are simplified representations of a real object or system.

Model

Explanation:

A representation of a real object or system in its physics, conceptual or structural form is called the model of that object or system. A model only represents an object or system but is not the object/system itself. An example of the model of a system can be a model representing the water cycle which symbolically explains the systemic process and an example of a model of an object can be a globe which is a representative of the earth.The model tries to simplify our understanding of the given object/system and hence there is a little deviation from the real object/system. The purpose of the model is usually to provide basic knowledge regarding that particular object/system by giving a simpler representation.
