This is probably best shown with the rather brilliant 4 Chords video by Axis Of Awesome. Try some different strumming patterns (get some help with strumming here) with those chords and see if you can hear anything you recognise.
Change the order and you’ll start to recognise even more. Try playing through those chords a few times, almost immediately you’ll start to hear songs you know as you play. In the key of C that gives us C, G, Am and F. If that doesn’t mean much to you, don’t worry. Well let me start by saying the relationship between the chords is I, V, Vi and IV. I guess the first thing you want to know is what those chords are.
