n. (Mathematics, Physics) quantity with magnitude and direction (represented by an arrow indicating its direction); (Biology) insect which carries diseases, means of disease transfer; route of a plane

Vector may refer to: In mathematics and physics:An element in a vector space, often represented as a coordinate vectorVector (spatial), an object defined by both magnitude and direction; in contrast to a scalar, an object with magnitude onlyProbability vector, a coordinate vector with nonnegative entries summing to one, representing a discrete probability distributionA one-dimensional, directional matrix: a row vector or column vector

1. <mathematics> A member of a vector space.
2. A line or movement defined by its end points, or by the current position and one other point. See vector graphics.
3. A memory location containing the address of some code, often some kind of exception handler or other operating system service. By changing the vector to point to a different piece of code it is possible to modify the behaviour of the operating system.
Compare hook.
