A vector is an ordered set of the similar type of scalar data items. The scalar item can be a floating point number, a logical value or an integer. Vector processing is the logical computation or arithmetic applied on vectors while in scalar processing only one or pair of data is processed. Thus, vector processing is much faster compared to scalar processing. When the scalar code is changed to vector form then it is known as vectorization. A vector processor is a special coprocessor, which is making to handle the vector computations.
