vector machines and parallel machines.both machines work fast but in different ways.for instance,a vector computer solves 100 problems as fast as possible.A parallel computer,on the other hand,divides the work.It shares 10 problems with 10 persons or 20 problems with 5 persons. In the end ,the vector works step by step to find information and analyze it, and the parallel works like the human brain by solving many things simultaneously.
