What is DotNetNuke (DNN) and who is it suitable for?

Hello, I've recently come across the name DNN. Could you explain in simple terms what DotNetNuke actually is? Is it a framework or a content management system (CMS) like WordPress? What types of websites can be built with it, and who is it best suited for—companies or developers?

What is the difference between a "Module" and a "Skin" in DNN?

I'm learning the basic concepts of DNN and I frequently encounter the terms "Module" and "Skin." Can someone explain the main difference between these two?
