A graphic is a visual representation of an object or image. Graphics are often contrasted with text, which is comprised of characters, such as numbers and letters, rather than images. Letters and Numbers belongs to Typography but they are graphics as well.

We are oriented to Computer graphics which could be either 2D (two dimensional) OR 3D (three dimensional).

2D graphics comes in two flavors : Raster and Vectors.

Raster are mostly used for digital photos, Web graphics, Icons, and other types of images. They are composed of a simple grid of pixels, which can each be a different color.

Vectors are made up of paths, which may be lines, shapes, letters, or other scalable objects. They are often used for creating logos, signs… Unlike raster graphics, vector graphics can be scaled to a larger size without losing quality.

3D graphics offer three dimensional drawing capabilities with option of 3D rendering such as CAD. It is used for 3D animations and incorporate usage of 2D graphics in three dimensional space.
