A LAN party is a temporary, sometimes spontaneous, gathering of people with computers, between which they establish a local area network (LAN), primarily for the purpose of playing multiplayer video games. The size of these networks may vary from the very small (two people) to very large installations. Small parties can form spontaneously, but large ones usually require a fair amount of planning and preparation. As of 2010, the world record for the size of a LAN party is 12,754 connected systems, set at DreamHack, in Jönköping, Sweden.

LAN party events differ significantly from LAN gaming centers and Internet cafes in that they generally require participants to bring your own computer (BYOC) and are not permanent installations, often taking place in general meeting places or residences.

Usually, smaller LAN parties consist of people bringing their computers over to each others' houses to host and play multiplayer games.

These are sometimes established between small groups of friends, and hosted at a central location or one that is known to all participants. Such events are often organized quickly with little planning, and some overnight events, with some stretching into days (or even weeks). Because of the small number of players, games are usually played on small levels and/or against bots.

A party is a gathering of people who have been invited by a host for the purposes of socializing, conversation, or recreation. A party will typically feature food and beverages, and often music and dancing as well.

Some parties are held in honor of a specific person, day, or event (e.g., a birthday party, a Super Bowl party, or a St. Patrick’s Day party). Parties of this kind are often called celebrations.

A party is not necessarily a private occasion. Public parties are sometimes held in restaurants, pubs or bars, and people attending such parties may be charged an admission fee by the host.

A birthday party is a celebration of the anniversary of the birth of the person who is being honored.

Birthday parties are a feature of many cultures. The guests may be asked to bring a gift for the honored person. In Western cultures, birthday parties are often accompanied by colorful decorations, such as balloons and streamers. In these cultures, a birthday cake is usually served with lit candles that are to be blown out after a "birthday wish" has been made. The person being honored will be given the first piece of cake. While the birthday cake is being brought to the table, the song "Happy Birthday to You" or some other dedicated birthday song is sung by the guests.
