Computer graphics refers to creating and manipulating pictures and drawings using a computer. There are two main types: passive graphics which have no interaction and active graphics which allow two-way communication and interaction between the user and hardware. Computer graphics has many applications including user interfaces, scientific visualization, animation, computer aided design, presentation graphics, image processing, and education/training.

- 11. PRESENTATION GRAPHICS Presentation Graphics is representing descriptions and facts using graphs. Various Graphs such as Piechart, bargraphs line charts are used. Used to summarize financial, statistical, mathematical, scientific data etc.
- 12. VISUALIZATION Scientific Visualization Business Visualization Computer graphics makes vast quantities of data accessible. Numerical simulations frequently produce millions of data values. Similarly, satellite-based sensors amass data at rates beyond our abilities to interpret them by any other means than visually. Mathematicians use computer graphics to explore abstract and high-dimensional functions and spaces. Physicists can use computer graphics to transcend the limits of scale.
- 13. IMAGE PROCESSING Manipulating images with a computer  Image processing generally involves three steps: Import an image with an optical scanner or directly through digital photography. Manipulate the image in some way. This stage can include image enhancement and data compression. For example: Image processing can be used to reduce the noise (that infernal spec that comes from nowhere) in an image. Output the result. The result is the image altered in some way. Â
