Question

Difference between array processor and vector processor

Answer 1

In computing, a vector processor or array processor is a central processing unit (CPU) that implements an instruction set containing instructions that operate on one-dimensional arrays of data called vectors.

Vector and array processing are essentially the same with small differences.

An array is made up of indexed collections of information called indices. Though an array can, in rare cases, have only one index collection, a vector is technically indicative of an array with at least two indices. Vectors are sometimes referred to as "blocks" of computer data.

Vector and array processing technology are most often seen in high-traffic servers.

Answer 2

Well, in the computing array as well as vector processing words are used for same defining but there is very slight difference between them.
While array is composed of index collections of data or information normally known as indices but having more then one index collection is not necessary. on the other hand  vector word used when there is two indices atleast.

Other than this words have approximate same meaning for implementing the instruction.
