Some versions of RO have chosen to hide the character count from the server selection window and disable the /who command to dispel accusations of population decline. Players can also see the population of the server they're currently in with the /who command. Players can only learn which servers are PVM or PVP through their publisher as the server selection window only shows population counts for each server. In RO, players have the option to choose from PVM or PVP servers. The last update the server received was Episode 13.3: El Dicastes. After the closure, iRO became the new official server for the area. Shortly after celebrating their 10 year anniversary. This can often be confusing as different versions of RO and RO2 occasionally use the same internal server names for their respective versions. Known as mRO, the server launched in 2003 by Game Flier Malaysia. The term 'server' can refer to a different version of the game, such as the Asia servers or the North America servers, or the internal servers in one version of the game. In MMORPGs such as Ragnarok Online and Ragnarok Online II, players have the option to choose from multiple servers to play the game.

A single server is designed to be accessed by multiple processes or devices.

A server is a device that provides functionality for other programs or devices, called 'clients.' This architecture is called the client–server model.
