Bitmap images are made up of and 8203 pixels but vector images are made up of and 8203 what?

Bitmap images are made up of pixels, which are the smallest units of a digital image, representing color at specific coordinates in a grid. In contrast, vector images are created using mathematical equations and geometric shapes, such as points, lines, and curves, allowing them to be scaled without loss of quality. This fundamental difference makes vector images ideal for designs that require resizing, like logos and illustrations.
