Vector Graphics:

. Uses mathematical equations to draw images.
. These are translated into points that are connected by lines/curves.

Raster Graphics:

. Digital images captured as set of sample of space.
. Raster is a grid of x, y coordinates on display space.
. Also referred to as 'bitmap' because it contains information that is directly mapped to display grid.
