Photoshop is raster graphics. Raster graphics are a grid of pixels. So are the pictures you take with a digital camera. Photoshop is good for editing photos or painting digitally.





Illustrator is vector graphics. Vector graphics are geometry based and are resolution independent. You can zoom in on a vector based image as much as you want and it won't have jagged edges. Like it's name suggests, it's good for making illustrations.
