           finding the vector sum of two or more vectors is vector
           addition (see under Addition).

From The Free On-line Dictionary of Computing (18 March 2015) :

  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.
