To be honest there isn't much of a difference.

MODEL - manages data
VIEW - data displayed to user
CONTROLLER - works as a mediator between the View and the Model and is used for request mappings.

MVC is a a very well know design pattern used for large scale applications. Eg- Java with Spring.

MODEL - manages data
VIEW - it holds the business logic and renders the template on to the URL mapped.
TEMPLATE - generally an HTML page displayed to the user.

MVT design pattern is suitable for both small scale and large scale applications. Eg- Python with Django.
