Multiprocessing is a type of system that has become standard in many commonly used devices, for example, laptop computers and smartphones. In a multi-processing system, multiple CPUs or processes work on a single motherboard. As such, they need to be connected in some way. A traditional system has a bus connecting all of the “cores” or processors together.
