Second Chance Page Replacement Algorithm. Web if all the pages have their reference bit cleared, then second chance algorithm degenerates into pure fifo. Web in this article, we discussed a second chance replacement as an efficient and versatile page replacement algorithm that effectively manages memory resources in various scenarios.
Apart from lru, opt and fifo page replacement policies, we also have the second chance/clock page replacement policy. Web in this article, we discussed a second chance replacement as an efficient and versatile page replacement algorithm that effectively manages memory resources in various scenarios. Web second chance (or clock) page replacement policy implementation of least recently used (lru) page replacement algorithm using counters not recently used (nru) page replacement algorithm Reference bit = 1 then: Web if all the pages have their reference bit cleared, then second chance algorithm degenerates into pure fifo. Set reference bit 0, leave page in.
