    Instances are servers like lemmy.world or sh.itjust.works.

    Federation is a shared language that lets the servers store content from similar servers on instances so users on instance 1 can see posts from instance 2.

    A forum is a message board, they have been around since the dawn of the web. It’s like the comment section on lemmy or reddit but without threading.
