What is the difference between raster data and vector data?

Vector data represents geographic data symbolized as points, lines, or polygons. Raster data represents geographic data as a matrix of cells that each contains an attribute value. While the area of different polygon shapes in a data set can differ, each cell in a raster data set is the same cell.
