In the VAX, user page tables are located at virtual addresses in the system space. What is the advantage of having user page tables in virtual rather than main memory? What is the disadvantage?
Answer to relevant QuestionsSuppose the program statement for (i = 1; i 6 6 = n; i + +) a[i] = b[i] + c[i]; Is executed in a memory with page size of 1,000 words. Let n = 1,000. Using a machine that has a full range of register-to-register ...In the S/370 architecture, a storage key is a control field associated with each page-sized frame of real memory. Two bits of that key that are relevant for page replacement are the reference bit and the change bit. The ...What is the difference between preemptive and non-preemptive scheduling? In a non-preemptive uni-processor system, the ready queue contains three jobs at time t immediately after the completion of a job. These jobs arrived at times t1, t2, and t3 with estimated execution times of r1, r2, and r3, ...List and briefly define four techniques for thread scheduling.
