Definitions

Pixel- a minute area of 
illumination on a display 
screen, one of many from which an image is composed.













Raster Graphics- digital images created or captured (for example, by scanning in a photo) as a set of samples of a given space. A raster is a grid of x and y coordinates on a display space. (And for three-dimensional images, a z coordinate.)









Vector Graphics-  is the use of geometrical primitives such as points, lines, curves, and shapes or polygons—all of which are based on mathematical expressions—to represent images in computer graphics.
