in Symmetric Multiprocessing, each processor performs all tasks including operating system functions and user processes. All processors are peers; no master-slave relationship exists between processors.

• True
• False

In Asymmetric Multiprocessing, each processor performs all tasks including operating system functions and user processes. All processors are peers: no master-slave relationship exists between processors.
