Site Collection and sites Mapped to controller and action methods on asp.net MVC

I came from an MVC architecture background and currently I am learning the architecture of SharePoint 2013. So can I make the following assumptions:-

1. Creating a new site collection in SharePoint 2013 is equivalent to creating new Controller class in asp.net MVc from an architecture and URL construction perspectives?

2. Is creating a new site under a site collection is equivalent to creating a new Action method under a controller class ?

Best Regards
