The owner is a superuser with sweeping access to everything in a Discord server. They can change the settings, add and remove roles, upload files media, manage permissions, and remove members from the server at their discretion. They can also change the server's name or even create or delete channels at will. An Administrator is a user who's been given certain privileges by the owner. They can do everything an owner can do, except they can't kick any of the other Admins or the owner from the server. In addition, they can't dethrone the owner and take over the crown unless the owner decides to give it up willingly. An Admin has more power than members but doesn't have free reign as the owner does.
