Since both "vector" and "raster" have been used without a real definition, I'll throw one in real quick:

• A vector image is an image in which the graphical components are stored as mathematical equations, thus making the image scalable without a loss of quality (because the larger or smaller image can just be recalcuated using the stored equation). These types of images often look like drawings.
• A raster image forms a picture by storing the color values of each pixel. This results in higher image quality than a vector, but the image does not scale well; when made larger, more pixels have to be added, and the color values have to be calculated using the existing surrounding pixels as a reference; thus, the image looks "pixelated" when blown up. Raster images often look more like photographs than drawings.
  • A vexel is a raster-based image made to look like a vector-based image.

Generally speaking, raster-based images are edited using Adobe Photoshop, whereas vector-based images are edited using Adobe Illustrator.
