- 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.
vector definition by Webster's New World
- 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: Modern Latin ; from Classical Latin bearer, carrier ; from vectus, past participle of vehere, to carry: see way
vector definition by American Heritage Dictionary
- 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.
- Pathology An organism, such as a mosquito or tick, that carries disease-causing microorganisms from one host to another.
- Genetics 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: Latin, carrier, from vehere, vect-, to carry; see wegh- in Indo-European roots.
- vec·toˈri·al adjective
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.
vector - Cultural Definition
In physics and mathematics, any quantity with both a magnitude and a direction. For example, velocity is a vector because it describes both how fast something is moving and in what direction it is moving. Because velocity is a vector, other quantities in which velocity is a factor, such as acceleration and momentum, are vectors also.
vector - Medical Definition
- An organism, such as a mosquito or tick, that carries disease-causing microorganisms from one host to another.
- A bacteriophage, a plasmid, or another agent that transfers genetic material from one location to another.
- A quantity, such as velocity, completely specified by a magnitude and a direction.
vector - Science Definition
- A quantity, such as the velocity of an object or the force acting on an object, that has both magnitude and direction. Compare scalar.
- An organism, such as a mosquito or tick, that spreads pathogens from one host to another.
- A bacteriophage, plasmid, or other agent that transfers genetic material from one cell to another.
