Please explian the codes on the game download pages?

I'm new to this site and not sure where to post my simple question, i know nothing about this site yet and i have a few questions to help me get started, 1st of all though i live in England and was wondering what all the codes mean at the end of the game downloads? and how do i format ready for my putting the games onto my daughters D's card? I`m sure someone out there will guide me through it all (I hope so anyway lol)
