Computer graphics may be defined as a pictorial or graphical representation of objects in a computer device.

The frame buffer of a system with one bit per pixel is called a bitmap.

The maximum number of points that can be displayed without overlap on a CRT screen is the resolution, for example, 1360 x 768

The System has multiple bits per pixel, its frame buffer is called pixmap.

Line clipping, Area clipping, Text clipping, and Curve/ Polygon clipping.

Emissive display converts electrical strength into light strength. The plasma panels.
The Non-emissive devices are the ones that convert the daylight or light from another source to pixel form. Liquid crystal show is an example.

The ratio of vertical pixels to the horizontal pixels needed to draw a length of one unit in both directions of the CRT is called the Aspect ratio. Usually, the aspect ratio is ¾.

A pixel is a short form of picture element. Every display screen point is referred to as a pixel.

The line type, style, width and colour are the attributes of the line.

The reflection is the transformation that creates a reflected picture of an object.

Dithering defines techniques for approximating halftones without reducing resolution pixel. Pictures printing in the newspaper are the best examples of using the dithering technique.

Fractals have the property that a shape can have the same degree of roughness no matter how much it is magnified.

Picture definition is stored as intensity values in a memory area known as the refresh buffer or frame buffer.
