What is the difference between vector and raster digital Illustration?

Scalable Vector graphics, (SVG) are created in Adobe Illustrator and have a clean smooth line or curve. They can be scaled to any size and retain the quality of the image for reproduction purposes. It is a much smaller file size than a raster image and can easily be sent via email. These bitmap graphics are usually files with extensions such as .EPS, .AI, BMP, .PDF

Rasterized, pixelated images are usually created in Adobe Photoshop and can also include photographs. The digital illustration done in a raster style is made up of very tiny squares called pixels. Lorraine's raster images are usually more painterly with a broader range of effects and brushes available in Photoshop. This file tends to be larger than the vector art file. These are usually files with extensions such as .PSD, .TIFF, .JPG
