- differs in the traditional way of making images and graphics. It refers to pictorial presentation and manipulation of an image data in a computer with the help of graphics hardware and software.

These are computer-based graphics that use only two-dimensional representation of geometric data generated by the computer.

These are graphics that use three-dimensional representation of the data generated by the computer.

- (Also known as bitmaps) is composed of million tiny blocks of color information called pixels.

- are characterized by the width and height of the image in pixels and the number of bits per pixel (a color depth, which determines the number of colors it can represents.)

- is made up of geometrical objects such as points, lines, curves, shapes and polygons all based on mathematical expressions.
