Vector \Vec"tor\, noun [L., a bearer, carrier. fr. vehere, vectum, to carry.]
1. Same as {Radius vector}.
2. (Math.) A directed quantity, as a straight line, a force, or a velocity. Vectors are said to be equal when their directions are the same their magnitudes equal. Cf. {Scalar}.
Note: In a triangle, either side is the vector sum of the other two sides taken in proper order; the process finding the vector sum of two or more vectors is vector addition (see under {Addition}).
From WordNet (r) 2.0 [wn]:
vector
noun
1: a variable quantity that can be resolved into components
2: a straight line segment whose length is magnitude and whose orientation in space is direction
3: any agent (person or animal or microorganism) that carries and transmits a disease; "mosquitos are vectors of malaria and yellow fever"; "fleas are vectors of the plague"; "aphids are transmitters of plant diseases"; "when medical scientists talk about vectors they are usually talking about insects" [syn: {transmitter}]

From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:
vector
1. 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}. 4. A one-dimensional {array}. (1996-09-30)
