A vector is represented by a straight line of specific length having an arrow head which shows its direction. This straight line is called the representative line of that vect…or. Vector variables are sometimes notated with arrow above them (particularly in handwritten physics formulae), and sometimes notated by using a bold-face font (particularly in print). Mathematically, at least for the vectors which crop up in classical mechanics, a vector can be represented in terms of components. In 3D space, for example, we can choose a set of three independent directions (e.g. north/south, east/west and up/down) and write our vector as a sum of three parts: a purely north/south-pointing part, a purely east/west-pointing part and a purely up/down-pointing part. The length of each part gives the component of the vector in the corresponding direction (note that the north/south-pointing part counts as positive if it points north, negative if it points south, and so on). This allows us to write such vectors in a convenient form for calculations, once a frame of reference has been agreed on. We simply list the components, writing something like v = (a, b, c) where v is the vector and a, b and c are the components in the frame of reference being used. In this notation, basic vector arithmetic is simple. For example: Scalar multiplication: nv = (na, nb, nc) where n is a real number. Vector addtion: v1 + v2 = (a1, b1, c1) + (a2, b2, c2) = (a1 + a2, b1 + b2, c1 + c2). (MORE)

Vector means that the images are created from algorithms (math) by the software you are using to create them. It's the complete opposite of raster in which the images ar…e pixel-based. Vector formats can be enlarged as much as you possibly could think of without losing quality of the image. Vector graphics are also usually created and used in CMYK format. Logos, illustrations, layouts, and most anything that is not a photo or photo-realism graphic is made in vector format. Particularly logos, so that those can easily be resized from as small as using it on a business card to as large as outdoor signage without becoming distorted at all. Vector Graphics use vectors and mathematical functions to describe images rather than fixed bitmaps. As a result the images can be cleanly scaled to any size without losing fidelity. It is also much easier (and computationally faster) to perform transformations on them quickly like sheering and rotation. Vector graphics are used whenever we want to make images that we might want to stretch out or shrink a lot. In particular: * most typographical font formats describe each letter using vector graphics. (In particular, the TrueType and Postscript font formats). * line drawings are typically drawn and stored as vector graphics * the Gerber file format (a subset of EIA RS-274) is a de-facto standard in printed circuit design. Practically all 3D graphics are drawn in vector graphics form. * Computer-generated imagery (CGI) in television and movies is almost always generated using vector graphics, often Blender files or POV files or VRML files or RenderMan files. Many physical objects have been designed using 3D versions of vector graphics * Nearly all CAD software uses some kinds of 3D vector graphics * The G-Code format (a subset of EIA RS-274) is used in many computer-controlled machine tools.

A vector is anything that carries a disease. It can be biological, as in the vector (ie: fly, mosquito, etc) creates it naturally or it can be mechanical as in the vector pick…s it up somewhere and transports it to you (ie: a fly lands on feces, then lands on your lunch!!!) Velocity Force (MORE)

Vector is a type of collection object that Java has. Vector is a class that implements the AbstractList class and is often used as an alternative to arrays since it automatica…lly extends the length of the list unlike arrays. A Vector can contain a collection of objects of any type. But it has fallen out of use due to the rise of the more convenient ArrayList class, but Vectors are still used for their security in multi threaded environment. Vectors are thread safe but array lists are not. An important fact to note is that Stack extends the Vector class. (MORE)

The vector is how the illness is spread. In cholera's case, the vector is contaminated water. That is how cholera is spread.

An augmented vector is a vector that is augmented with an extra dimension. This new dimension always takes on the value of 1. e.g. X = (5, 2) X' = (5, 2, 1) where X' is the au…gmented form of vector X. (MORE)

A vector whose direction (angles) and line of application are fixed, but whose point of application is not fixed.

Force, velocity, acceleration, and displacement are vectors. Mass, temperature, time, cost, and speed are scalars (not vectors).

Traditionally a vector has two components: A directionA magnitude In addition, one might accept that a vector also contains a starting point, although this is technically not …part of a vector. A vector may be denoted or described as: An initial pointA terminating point Such as AB (with a vector line above it) where A is the initial point, and B is the terminating point. I generally do not prefer this denotation, but some do. (MORE)

A vector is something which has both magnitude and direction. Examples include velocity which is speed (magnitude) in a given direction. When written usi…ng orthogonal components vectors are written as a column of numbers in parentheses (a one-dimensional array). (MORE)
