Dual-processor (DP) systems are those which
contains two separate physical computerprocessors in the same
chassis. In dual-processor systems the two processors can either be located on
the same motherboard or on separate boards.
Understanding Dual Processors, Hyper-Threading Technology, and Multi Core Systems This paper will provide you with a basic understanding of the differences among several computer system architectures—dual-processor systems, Intel Xeon processors with Hyper-Threading Technology, dual-core processor systems, and multi-core processor systems—capable of executing two or more programs, for example in a multitasking environment or multiple threads within one program.
