This document discusses vector graphics and raster graphics. Vector graphics use mathematical equations to define points and can be scaled to any resolution without losing quality, while raster graphics use a grid of pixels that become pixelated when scaled up. Common file formats are AI, PDF, SVG for vector graphics and PNG, JPEG, GIF for raster graphics. Software like Illustrator and Inkscape are used for vectors, while Photoshop and Gimp are used for rasters. Overall, vectors are more flexible and suitable for more applications.
