a person or entity that passes along an urban legend or other meme from the concept of biological vector
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
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

an agent used as a vehicle for transfer A disease vector is an agent that transfers a pathogen from one organism to another (e g , an insect) A viral vector is an engineered virus used to introduce genes into cells, or a live virus used as an antigen delivery vehicle in a vaccine
a directed quantity, one with both magnitude and direction; an element of a vector space
* - displays and databases build all geographic features from points, that is from discrete X-Y locations Lines are constructed from strings of points, and polygons (regions) are built from lines which close Vector methods are sometimes contrasted with raster techniques which record geographic features within a matrix of grid cells The choice between vector and raster GIS has much to do with the application being considered since both methods have strengths and weaknesses Many current GIS permit transformation between vector and raster input and output
in vaccine research, a bacterium or virus that does not cause disease in humans and is used in genetically engineered vaccines to transport genes coding for antigens into the body to induce an immune response (See also vaccinia and canarypox )
{i} (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
an abstraction of the real world where positional data is represented in the form of coordinates In vector data, the basic units of spatial information are points, lines and polygons Each of these units is composed simply as a series of one or more coordinate points For example, a line is a collection of related points, and a polygon is a collection of related lines Vector images are defined mathematically as a series of points joined by lines Vector-based drawings are resolution independent This means that they appear at the maximum resolution of the output device, such as a printer or monitor Each object is self-contained, with properties such as color, shape, outline, size, and position on the screen
The agent used to carry new DNA into a cell Viruses or plasmids are often used as vectors
Vectors are said to be equal when their directions are the same their magnitudes equal
'a carrier' In genetic manipulation the vehicle by which DNA is transferred from one cell to another An agent of transmission; for example, a DNA vector is a self-replicating segment of DNA that transmits genetic information from one cell or organism to another [CUB]
1 A plasmid or virus used in genetic engineering to insert genes into a cell 2 An agent, usually an insect or other animal, able to carry pathogens from one host to another 3 An arthropod or other agent that carries microorganisms from one infected individual to another
A vector is an insect or other organism that causes a disease by carrying a germ or parasite from one person or animal to another. In mathematics, a quantity characterized by magnitude and direction. Some physical and geometric quantities, called scalars, can be fully defined by a single number specifying their magnitude in suitable units of measure (e.g., mass in grams, temperature in degrees, time in seconds). Quantities like velocity, force, and displacement must be specified by a magnitude and a direction. These are vectors. A vector quantity can be visualized as an arrow drawn in a specific direction, whose length is equal to the magnitude of the quantity represented. A two-dimensional vector is specified by two coordinates, a three-dimensional vector by three coordinates, and so on. Vector analysis is a branch of mathematics that explores the utility of this type of representation and defines the ways such quantities may be combined. See also vector operations
