Vector Processing
A vector is an ordered set of similar type of scalar data items. The scalar tem may be a logical value, an integer or a floating point number. Vector processing is the arithmetic or logical computation implemented on vectors while in scalar processing only one or pair of data is processed. Consequently vector processing is faster in comparison to scalar processing. When the scalar code is transformed to vector form then it is known as vectorization. A vector processor is a special coprocessor that is intended to handle vector computations.
