Vector \Vec"tor\, n. [L., a bearer, carrier. fr. vehere, vectum,
   to carry.]
   1. Same as {Radius vector}.

   2. (Math.) A directed quantity, as a straight line, a force,
      or a velocity. Vectors are said to be equal when their
      directions are the same their magnitudes equal. Cf.
      {Scalar}.

   Note: In a triangle, either side is the vector sum of the
         other two sides taken in proper order; the process
         finding the vector sum of two or more vectors is vector
         addition (see under {Addition}).

vector
     
        1.  A member of a {vector space}.
     
        2.  A line or movement defined by its end points, or
        by the current position and one other point.  See {vector
        graphics}.
     
        3.  A memory location containing the address
        of some code, often some kind of {exception} handler or other
        {operating system} service.  By changing the vector to point
        to a different piece of code it is possible to modify the
        behaviour of the operating system.
     
        Compare {hook}.
     
        4.  A one-dimensional {array}.
