Types of game servers

Game servers can be classified as listen servers and dedicated servers. Listen server refers to a situation in which the server typically runs in the same process as the game client, allowing a player to both host and participate in the game. As a side effect, the server is usually terminated when the client is. Listen servers are operated mostly by individuals, often in LAN Party situations rather than over the Internet, and usually with a lower number of players due to the increased processing and bandwidth requirements associated with operating both server and client simultaneously on the same machine. Dedicated servers are servers which run independently of the client. Such servers may be run by individuals, but are usually run on dedicated hardware located in data centers, providing more bandwidth and dedicated processing power. Dedicated servers are the preferred method of hosting game servers for most PC-based multiplayer games. Massively multiplayer online games run on dedicated servers usually hosted by the software company that owns the game title, allowing them to control and update content. In many cases they are run on clustered servers to allow huge environments and large player counts.
