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]

Vector : \Vec"tor\, n. [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).

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.

Vector : Vector: In medicine, a vector is a carrier. The best way to understand a vector is to recall its origin as a word. Vector is the Latin word for a "bearer."
In parasitology (the study of parasitic organisms), the vector carries the parasitic agent. For example, in malaria a mosquito serves as the vector that carries and transfers the infectious
agent (Plasmodium), injecting it with a bite.
In molecular biology, a vector may be a virus (or a plasmid); a piece of foreign DNA is inserted in the vector genome to be carried and introduced into a recipient (host) cell.
In physics, there are vectors but they go beyond the biomedical realm (except in cardiology).
