Tiles are usually referred to as small subimages that are part of a bigger image. Tiles usually have the same size, so they are easily compacted into one rectangular area. You can see tiles mostly in 2D games, especially in platform games, RPGs and even 3D action games. The rectangular property makes tiles very efficient in the question of accessing specific subimages from a large tileset. You can store the whole tileset into the graphical memory, and with the knowledge of the subimage positions, you can easily select the tiles you need.
