vector

The term vector is used in mathematics, physics, computer graphics and engineering, and also in SNA architecture.

1. In mathematics and physics, a vector is described as a spatial quantity that is described by the initial coordinates, the angle and the magnitude. A vector is represented by an arrow. This model is also used in computer graphics.
2. In SNA architecture, a vector is understood to be a data segment of an SNA message. A vector is limited to a length field, it consists of a key that describes the vector type and vector-specific data.
