- 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.
- Biol. an animal, esp. an insect, that transmits a disease-producing organism from a host to a noninfected animal
- a mathematical expression denoting a combination of magnitude and direction, as velocity
- a directed line segment representing such an expression
- an ordered set of real numbers, each denoting a distance on a coordinate axis
- the particular course followed or to be followed, as by an aircraft; compass heading
Origin of vectorModern Latin ; from Classical Latin bearer, carrier ; from vectus, past participle of vehere, to carry: see way
- Mathematics a. A quantity, such as velocity, completely specified by a magnitude and a direction.b. A one-dimensional array.c. An element of a vector space.
- An organism, such as a mosquito or tick, that carries disease-causing microorganisms from one host to another.
- A bacteriophage, plasmid, or other agent that transfers genetic material from one cell to another.
- A force or influence.
- A course or direction, as of an airplane.

Origin of vectorLatin, carrier, from vehere, vect-, to carry; see wegh- in Indo-European roots.
- (mathematics) A directed quantity, one with both magnitude and direction; the signed difference between two points.
- (mathematics) An ordered tuple representing a directed quantity or the signed difference between two points.
- (mathematics) Any member of a (generalized) vector space.
- The vectors in are the single-variable polynomials with rational coefficients: one is .
- (aviation) A chosen course or direction for motion, as of an aircraft.
- â€‹(epidemiology) A carrier of a disease-causing agent.
- (sociology) A person or entity that passes along an urban legend or other meme.
- (psychology) A recurring psychosocial issue that stimulates growth and development in the personality.
- The way in which the eyes are drawn across the visual text. The trail that a book cover can encourage the eyes to follow from certain objects to others.
- (computing, operating systems) A memory address containing the address of a code entry point, usually one which is part of a table and often one that is dereferenced and jumped to during the execution of an interrupt.
- (programming) A one-dimensional array.
- (programming): The term vector is used loosely when the indices are not (either positive or non-negative) integers.
(third-person singular simple present vectors, present participle vectoring, simple past and past participle vectored)
- To set (particularly an aircraft) on a course toward a selected point.
From Latin vector (â€œcarrierâ€), from vehÅ (â€œI carry, I bearâ€).
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.
(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.
