A continent (or landmass) is the largest geographical subdivision of a planet or world. Continents, which can actually be parts of larger continents, are broken down into regions or zones, but some break them down into groups of regions or zones called subcontinents.
At the time of the War of the Ancients, 10,000 years ago, Azeroth had one singular continent called Kalimdor. The Sundering broke apart this landmass into various continents and islands. Currently, the ancient landmass known as Kalimdor would be called a supercontinent since all the land was once a part of it.
The number of continents has grown and shrunk as time has gone by. This is due to the discovery of new lands, the importance of those lands, and maybe politics. As of Cataclysm, there were three large continents in the game: the Eastern Kingdoms (formed of three subcontinents) in the east, Kalimdor (formed of three subcontinents) in the west, and Northrend in the north. These continents are bordered by the Great Sea which seem to occupy the whole of the planet. As of the Mists of Pandaria expansion, the continent of Pandaria was revealed as part of Azeroth to the south of the Maelstrom. As a part of the Legion expansion, the Broken Isles were revealed (south of Howling Fjord, Northrend, and east of the Maelstrom) as essentially a separate continent.

Outland does not have continents in the traditional sense. Outland is itself a single continent that represents the remnants of what was once Draenor. Draenor may have had more than one continent before it was shattered, but these land masses have names lost to the mists of history.
