Question

Difference between multiprocessor and multicomputer based on structure

Answer 1

 The difference between a multiprocessor system and a multicomputer system is the number of computers involved in each. Both are multiprocessing environments: Both use more than one CPU at a time. A multiprocessor system is a single computer that operates with multiple CPUs, and a multicomputer system is a cluster of computers that operate as a singular computer. Multiprocessing environments can operate with CPUs sharing an operating system -- called symmetric multiprocessing -- or with each CPU running an individual instance of the operating system -- called Massively Parallel Processing.
