MVVM - Model-View-View Model
The controller is replaced with a view model. the view model sits below the UI layer. The view model exposes the data and command objects that the view needs. You could think of this as a container object that view goes to to get its data and actions from. The view model pulls its data from the model(s) below.
MVC - Model–View–Controller
The view sits at the top of the architecture, the controller sits below the view. The model sits below the controller. So the view knows about the controller, the controller knows the model. The view is notified when the model changes.
MVP - Model-View-Presenter
The controller is replaced with a presenter. The presenter sits at the same level as the view. The presenter listens to the events of both the view and the model and mediates the interactions between both the view and model.
