And By default we always consider hierarchial access or direct access. thor asked Nov 23, 2016 thor 266 views answer comment Share Follow See all 3 Comments See all 3 3 Comments reply Amitabh Tiwari 1 commented Nov 23, 2016 reply Follow Share Yes correct. By default its hierarchical. 0 votes 0 votes Gate Mission 1 commented Nov 23, 2016 reply Follow Share Yes by default its hierarchial but the term page fault service time includes memory access time [so no need to add 10 with page fault serive time] so correct sol'n is 0.01 * 50 + 0.99 * 10 --> 10.4 ns 0 votes 0 votes Amitabh Tiwari 1 commented Nov 23, 2016 reply Follow Share No. It should be page_fault_rate(MM_access_time + Page_fault_service_time)... see after accessing MM only you came to know that the page from secondary memory needs to be swapped in. That process of swapping in, making room in MM,deciding on which one to replace is PAGE FAULT SERVICE TIME. 1 votes 1 votes Please log in or register to add a comment.
