Is the class diagram same thing as class model?

I had been doing some UML class diagram examples from the recent exams for my software design course, and I found one where it says:"Design a class model for a specific problem, by using MVC and STATE pattern, but no need to include getters and setters." Is this the same thing as the regular class diagram? I've been googling and I found nothing UML based by searching for class MODEL.

The model is abstract. A diagram is a view on the model. UML offers a number of different diagrams. There are mainly two categories: static and behavioral. Class diagrams fall under the static category and they show how the classes in the model are related to each other. You can create multiple class diagrams like one with all classes (assuming that you have a rather limited number of classes) and/or one per class with that in focus. Or you have sub-domains with related classes placed in one diagram. The behavioral diagrams shed light on how class instances communicate with each other at run time.

As a side note you can think of it in terms of Platon's Cave Allegory. The diagrams are the shadows of the real world projected by a fire to the wall you can see from you chained position.

"Design a class model" means: "Create one or more class diagrams that together form a consistent model".

A model in computer science is a graphical representation of (a piece of) software or of (a part of) the business domain in order to help people know or understand the subject the model represents (see wikipedia). This graphical representation may consist of one or more diagrams.
