1. composition
The placement or arrangement of visual elements or ingredients in a work of art, as distinct from the subject of a work.
The term composition means 'putting together,' and can apply to any work of art, from music to writing to photography, that is arranged or put together using conscious thought.
In the visual arts, composition is often used interchangeably with various terms such as design, form, visual ordering, or formal structure, depending on the context. In graphic design for press and desktop publishing composition is commonly referred to as page layout.

2. There are two types of computer graphics:
Line
There are two types of computer graphics:
raster graphics, where each pixel is separately defined (as in a digital photograph)
vector graphics, where mathematical formulas and geometric points, lines, curves an shapes are used to draw and represent images in computer graphics.

3. Balance
Symmetrical balance can be described as having equal "weight" on equal sides of a centrally placed fulcrum. It may also be referred to as formal balance. When the elements are arranged equally on either side of a central axis, the result is Bilateral symmetry. This axis may be horizontal or vertical. It is also possible to build formal balance by arranging elements equally around a central point , resulting in radial symmetry.

4. Asymmetrical balance, also called informal balance, is more complex and difficult to envisage. It involves placement of objects in a way that will allow objects of varying visual weight to balance one another around a fulcrum point. This can be best imagined by envisioning a literal balance scale that can represent the visual "weights" that can be imagined in a two dimensional composition.

5. Movement
Movement shows actions, or alternatively, the path the viewer's eye follows throughout an artwork. Movement is caused by using elements under the rules of the principles in picture to give the feeling of motion and to guide the viewer's eyes throughout the artwork

6. Pattern/Rhythm
Pattern and rhythm is showing consistency with colors or lines. Putting a red spiral at the bottom left and top right, for example, will cause the eye to move from one spiral, to the other, and everything in between. It is indicating movement by the repetition of elements. Rhythm can make an artwork seem active.
