n concurrent processes share a paged memory.
(a)
Assuming page replacement with a fixed number of frames,determine the optimal number of concurrent processes, n, using theL = S heuristic.
(b)
If the system uses page replacement with a variable number offrames, the number of concurrent processes, n, is determinedautomatically. Assume:
Determine the number of concurrent processes, n, that can runconcurrently.
