What is World of Warcraft pvp?

Answer 1

PvP (Player-versus-Player) is an activity you can do in World of Warcraft, where you compete against other players. There are several ways in which this is possible:

1) World PvP/Open zones

Some places, like Tol Barad and Wintergrasp, have regular timers at which PvP battles are fought.

2) Battlegrounds

You can join battlegrounds, whether alone, in a group or as a guild, to compete against a team of players from the opposite faction (Alliance versus Horde) to gain honor and reputation with the BG factions.

3) Arenas

Arenas are teams of 2v2, 3v3 or 5v5 players who are set against each other in one of several random arenas. In this type of fight, you can find yourself facing teams of the same faction, as well as the opposite faction.

Answer 2

Plaver versus Player. It is where you fight other live players, not NPCs (Non player Characters). PvP includes battlegrounds and arenas. There is also world PvP where you attack and can get attacked by anyone of the opposite faction.

If you are new to World of Warcraft, it might be best to level your first toon on a PvE server rather than a PvP server as on a PvE server you can not be attacked unless you specifically mark yourself as PvP.
