- The definition of a vector is a quantity that has both size and direction, or an insect that is a carrier of a disease-producing organism.
- An example of a vector is wind speed because it is measured with two factors - speed and direction.
- An example of a vector is a disease carrying bug.

From Latin vector (“carrier”), from vehō (“I carry, I bear”).
The "person or entity that passes along an urban legend or other meme" sense derives from the disease sense.
vector - Computer Definition
- A mathematical expression of a quantity, such as velocity, that possesses both magnitude (i.e., amplitude) and direction, and that may or may not be a function of time. See also amplitude.
- A directed line segment of such an expression. See also HCV and VQC.
- A set of numbers in an order that has meaning when each position is mapped to a corresponding dimension.
- In video, a frequency or series of frequencies associated with a video signal. See also vector quantization.
(1) In computer graphics, a line designated by its end points (X-Y or X-Y-Z coordinates). When a circle is drawn, it is made up of many small vectors. See vector graphics and graphics.
(2) In matrix algebra, a one-row or one-column matrix.
(3) An airplane's travel path.
(4) The term is used generically for "pathway" or "avenue" or even an influence of some type. For example, "x, y and z provide multiple vectors for malware intrusion" means there are multiple passageways for intrusion to occur.
