Discussion
Which of the following statements is true about symmetric multiprocessing?
Answer: B
Correct answer: Useful for situations where data must remain in memory to process.
Symmetric multiprocessing gives every processor access to one shared memory, so a large working set can be held once and worked on by all of them. The other options are wrong in detail: one copy of the operating system is shared rather than resident in each processor, and memory contention is the characteristic difficulty of the architecture rather than an unlikely one.
