What is the model for in MVC?

Question

Design patterns

What role does the model play in MVC? Controller and View with them everything is clear.
There are always at least several models used on one page.
For example. on the product page in IM, there are a bunch of other entities besides the product. This is the user and articles and news, and so on. And all this is displayed at once)
What then is the point of the model?

Answer 1

You don't seem to know how to google

1. MVC for the web: it couldn't be easier
   
2. M in MVC: why models are misunderstood and underestimated
   
3. MVC Concept for Dummies
   

Answer 2

A model is not only entities, models mean all business logic (Services, helpers, database requests, etc.)

Answer 3

VIEW - a stupid template on html
CONTROLLER - accepts a request and calls the desired model
MODEl - all the logic - what to request from the database, what to write to the database, how to withdraw from the database.
