From The Free On-line Dictionary of Computing (30 December 2018) :

  Cartesian product
      (After Renee Descartes, French philosper and
     mathematician) The Cartesian product of two sets A and B is
     the set
     	A x B = (a, b) | a in A, b in B.
     I.e. the product set contains all possible combinations of one
     element from each set.  The idea can be extended to products
     of any number of sets.
     If we consider the elements in sets A and B as points along
     perpendicular axes in a two-dimensional space then the
     elements of the product are the "{Cartesian coordinates" of
     points in that space.
     See also tuple.
