A realm is an area that is ruled by something. If you are a controlling cook who doesnât like anyone to do anything else in the kitchen, then the kitchen is your realm. Realm comes from the French for kingdom, but since there arenât so many kings or queens left in the world, youâll more often find it referring to non-royal spheres. That could be the sphere of a special kind of knowledge, like the realm of biology, or the political realm.
A realm is an instance of the World of Warcraft (0100) game world. Realms are hosted on physical devices called servers (for this reason, the terms realm and server are often used interchangeably). To play 0100, you must first choose a server (realm) to play on. You then connect to this realm over the Internet. Blizzard has servers in the US, Australia, Europe, China, Brazil and Korea (see Localization).
