Vectors in math and physics are typically graphed as arrows pointing in the direction of a quantity such as velocity. The length of the arrow shows its magnitude. This makes it easy to add vector quantities (you line up the tail of one arrow with the point of the other).

In [[computer]] science, '''vector''' has two meanings: that of mathematics (as described above), and as a synonym of [[array]].  The [[C++ programming language]] [[Standard Template Library]] uses the term in the second sense.  The term is used in both senses in the domain of 3D graphics programming.

In computer hardware, '''vector''' indicates an [[array]] of numeric values stored in memory.  For instance, a '''vector processor''' is a processor which specializes in performing operations on these arrays of numbers.
