What defines asymmetric multiprocessing?

• A. All processors share the same task equally
• B. Processors have specific roles and may run different processes
• C. Processors only perform I/O operations
• D. All processors are equal in terms of performance

Answer: (B)

Asymmetric multiprocessing is characterized by the division of labor between processors where each processor has specific roles or functions. This means that processors may not operate on the same tasks concurrently; instead, they can be assigned different processes based on certain criteria, such as the type of workload or the specific function needed. For example, one processor might handle user interface tasks while another manages background processes. This arrangement can lead to more efficient use of resources because each processor can be optimized for its assigned role. In contrast, the other options suggest scenarios that do not accurately reflect the nature of asymmetric multiprocessing. For instance, the idea that all processors share the same task equally aligns more with symmetric multiprocessing, where tasks are distributed evenly among all processors. Additionally, the notion that processors only perform I/O operations is too restrictive and does not encapsulate the variety of functions that processors in an asymmetric system might undertake. Lastly, claiming that all processors are equal in terms of performance contradicts the very idea of asymmetric architecture, where different processors may have different capabilities and responsibilities.
