| Colour Depth | Color depth, also known as bit depth, is either the number of bits used to indicate the color of a single pixel |
| Metadata | A set of data that describes and gives information about other data. |
| Vector Graphics | 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. |
| Bitmap Graphics | A bitmap graphic is composed of many tiny parts, called pixels, which are often many different colours. It is possible to edit each individual pixel. |
| Raster Graphics | Raster graphics are 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. |
