Drawing programs such as Adobe Illustrator create vector graphics which are made up of lines and curves defined by mathematical objects called vectors. Vectors describe an image according to its geometric characteristics. Vector graphics are RESOLUTION-INDEPENDENT - that is, they can be scaled to any size and printed at any resolution without losing detail or clarity. As a result, vector graphics are the best choice for representing bold graphics that must retain crisp lines when scaled to various sizes. Examples of Vector graphics are files created by Adobe Illustrator, Macromedia Freehand, or Corel Draw that does NOT contain rasterized images. The most common file output for these programs is .EPS.

If you are an owner of Adobe Illustrator 10 you can obtain more information in your manual in Chapter 2, page 39.
