When people gather in usually large groups to play multiplayer online games and connect their computers to a Local Area Network (LAN) they enjoy a LAN party.
In LAN parties either people play against each other or teams try to defend contesting groups in the form of so called clans for sponsored prize money and fun.
If players bring their own hardware it will be tuned for gaming with as much RAM as possible and the fastest processor they can afford, often over-clocked in an effort to have a small advantage over rivals.
Famous games in LAN parties include World of Warcraft (WoW), Starcraft and Unreal Tournament for example. The latest events, LAN party news and much more can be found here.
