Summary  
This chapter explains the fundamental difference between raster (pixel-based) and vector (mathematical equation–based) data representations, highlighting how vector graphics remain sharp at any scale while raster images pixelate.  

General domain of usage  
Digital graphic design and illustration

Understanding the **difference between raster and vector graphics** is important when using Adobe Illustrator, as it primarily deals with vector graphics but can also work with raster images but not as complicated as how Photoshop deals with them.

Here's a comparison of raster and vector graphics in the context of Adobe Illustrator:

Composed of a grid of individual pixels, where each pixel has a specific color value. Common raster formats include JPEG, PNG, GIF, and BMP.

Created using mathematical equations and geometric primitives like points, lines, and curves. Common vector formats include AI (Illustrator), SVG, EPS, and PDF.

Resolution-dependent; scaling up results in pixelation and a loss of quality.

Resolution-independent; can be scaled infinitely without losing quality.

Larger file sizes, especially for high-resolution or complex images.

Generally smaller file sizes, though complex illustrations can increase size.

Editing pixels can degrade quality, and fine adjustments are difficult.

Easily editable without losing quality, with tools like Adobe Illustrator offering precision.

Best for photographs, textures, and detailed images with complex colors.

Ideal for logos, icons, typography, and any design that requires resizing.

Capable of capturing intricate details and subtle shading.

More simplified in terms of color and detail; not suitable for highly detailed images like photos.

Resolution (DPI) must match print requirements to avoid pixelation.

Ideal for printing at any size with sharp, crisp output.

Now, let's see a practical example of that.

So, you can work with both raster (bitmap) images and vector graphics in Adobe Illustrator. Just be mindful of the resolution, and cleverly integrate them in your design.
