How does controller interact with view or model in rails?

I am new to RoR, so i don't understand the internal mechanism of interaction between view and controller. In any controller we can see the code like that:

class ProductsController < ApplicationController
end

How does ruby interpreter knows where to get ApplicationController class without any 'require' statment. Also, how does our controller knows about all models. I mean we if we have product model we can use in our controller the code like: 

Product.find(1);

But how actually controller know about the model class

For models, open a rails console in your app and type:

$LOAD_PATH

you will see that the models class is pretty early. This is how auto_loading in Rails is handled.

For views, there is a views_paths which can be manipulated and is outlined here: http://api.rubyonrails.org/classes/AbstractController/ViewPaths/ClassMethods.html
