title: What is the difference between parsys component and responsive layout in AEM
body: <p>I've realised that I can include <strong>parsys</strong> component to a page to allow content authors to add components on that place. Now when I was reading about responsive layout (<strong>responsivegrid</strong>) component, it seems like it's doing the same?</p>
  
  <p>I am interested in the difference, what should be used and in which case.
  There's a lot more in AEM documentation about Responsive layout, then about parsys so if someone can explain me this in a simple way or with some examples, I would be grateful.</p>
