I am currently learning how to make advanced usage of WPF via the Prism (Composite WPF) project.

I watch many videos and examples and the demo application StockTraderRI makes me ask this question:

What is the exact role of each of the following part?

SomethingService: Ok, this is something to manage data
SomethingView: Ok, this is what's displayed
SomethingPresentationModel: Ok, this contains data and commands for the view to bind to (equivalent to a ViewModel).
SomethingPresenter: I don't really understand it's usage
SomethingController: Don't understand too

I saw that a Presenter and a Controller are not necessary but I would like to understand why they are here. Can someone tell me their role and when to use them?
