Describe the differences between symmetric and asymmetric multiprocessing. What are three advantages and one disadvantage of multiprocessor systems?
Symmetric multiprocessing treats all processors as equals and I/O can be processed on any CPU. Asymmetric multiprocessing has single master CPU and the remainder CPUs are slaves. The master distributes tasks between the slaves, and I/O is usually done by the master only. Multiprocessors can save money by not duplicating power supplies, housings, and peripherals.
They can execute programs more rapidly and can have enhanced reliability.
They are also more difficult in both hardware and software than uniprocessor systems.
