Vector vs Raster (Bitmap) Graphics

Understanding the difference between vector graphics — which are mathematical sets of instructions on how to display an image — and raster images — which are collections of coloured squares arranged on a grid — is crucial to creating effective designs using computer software. Whether it’s designing a logo, making a web page, or creating a handout for your students, understanding the different types of images and when each is best suited for the job will help you get better results from your design work.

Check out this video from Adobe about the difference between vector graphics and raster graphics. It also explains a bit about Adobe Illustrator, which is the industry standard tool for creating vector graphics and combining them with other elements.
