Can you explain what the term 'model' means in MVC architecture?

In MVC (Model-View-Controller) architecture, the Model is responsible for working with data and the application's business logic. It stores the application's state, manages data, interacts with databases or other sources, and implements data processing rules. The Model does not handle displaying information — that is the task of the View. For example, in PHP, the Model can be a class that retrieves data from a database, processes it, and provides it to the Controller for further transmission to the View.
