Cloning vectors are used to increase the number of copies of the cloned gene or to amplify a foreign gene. Expression vectors are used to increase the expression of the foreign gene product.

What are difference between scalars and vectors
Vectors have a direction associated with them, scalars do not.
Coplanar :The vectors are in the same plane.Non coplanar :The vectors are not in the same plane.
All vectors that are perpendicular (their dot product is zero) are orthogonal vectors.Orthonormal vectors are orthogonal unit vectors. Vectors are only orthonormal if they are both perpendicular have have a length of 1.
A cloning vector that contains a highlhy active prokaryotic promoter just upstream of a restriction site where the eurkaryotic gene can be inserted in the correct reading frame. Such expression vectors allow the synthesis of many eukaryotic proteins in bacterial cells.
