2. A one-dimensional array.
3. 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.

Why A unit vector is a vector but a vector is not a unit vector?
A unit vector is one which has a magnitude of 1 and is often indicated by putting a hat (or circumflex) on top of the vector symbol, for example: Unit Vector = â, â = 1.The quantity â is read as...
Is vector A parallel vector B given that vector A is equal to the zero vector and vector B is equal?
The zero vector is both parallel and perpendicular to any other vector. V.0 = 0 means zero vector is perpendicular to V and Vx0 = 0 means zero vector is parallel to V.
Why a unit vector is aone type of vector but a vector is not a unit vector?
A unit vector is a vector whose magnitude is one. Vectors can have magnitudes that are bigger or smaller than one so they would not be unit vectors.
Why you call unit vector as vector?
because it has an orientation(a direction) it also helps later on with certain operations, but it is a vector because it has a length(1) and a direction(whatever that may be)
If vector A is perpendicular to vector B and C then Vector A is parallel to?
Vector A is parallel to the cross product of vectors B and C, and it is parallel to the axis that neither B or C lie along if the two other axes are defined as the axes that B and C lie along.
