![Blurred answer](/static/compass_v2/solution-images/blurred-answer.jpg)
- Consider a program that generates the following set of page references: AC BDBAEFBFAGEFAAFBACGF Assuming that the program is given 4 page frames, how many page faults are generated using the following page replacement algorithms: a) FIFO b) LRU c) OPT Show the contents of the 4 page frames after every access and indicate when page faults occur. Assume all frames are empty at the beginning of the sequence. For example, the first page access (to page A) will cause a page fault, since no pages are loaded into the frames. Page A will be loaded into the first frame. This indicated as below.List the steps needed to handle page faultsolve questions: 8, 5, 1, 2, 5, 3, 5, 6, 2, 6 Assuming that all frames are initially empty, indicate the contents of memory after each reference, and how many page faults are found for the FIFO page replacement scheme with 3 frames.
- What is weak collision Resistance?What is a segmentation fault and page fault? Also briefly explain the difference between the segmentation fault and the page fault.using C/C++. Determine the number of page faults and page hits by considering the Frame size=3, Reference String =11 13 10 14 15 12 11 19 18 16 15 17 14 16 19 21. and imnlomont Ontimal olacemon
- A paging scheme uses a Translation Look-aside Buffer (TLB). A TLB-access takes 10 ns and a main memory access takes 50 ns. The effective access time(in ns) is_?(if the TLB hit ratio is 90% and there is no page-fault)What is a dirty block?For example, consider the situation of a page fault. What part of the operating system do they have a connection to? What does this mistake suggest, in the most fundamental sense, is unclear.
- 10. Consider 2 level page table with outer page has 16 4KB pages, and each entry being 8 bytes long. How many entries can this 2-level page table contain? (Show your steps)What Is vector lane?a) Explain the complete mechanism of selective repeat ARQ in 3, 4 , and 5 sending and receiving window size scenario and also which problems are addressed in this scheme.
