Epidavros is right.

Think of vector data as the outline of the continents of a world map.

Think of raster data as the topographic model of the earth's surface, there is not "beginning or end", but each point on the surface (raster) has a unique value (elevation).

Raster data means bitmap images.

Vector data means lines and curves, and the bound shapes they can make.
