**Instructions**: Please write the final answer in the following answer table and the in-progress work if there is after each question. --- **2. Given the cache line set and page set as follows, what are the miss ratios of OPT, FIFO, and LRU?** | | **page** | 1 | 2 | 3 | 4 | 5 | 7 | 9 | 3 | 1 | 4 | 2 | 6 | 7 | 9 | 5 | |-----|----------|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---| | | **cache line 1** | | | | | | | | | | | | | | | | | | **cache line 2** | | | | | | | | | | | | | | | | | | **cache line 3** | | | | | | | | | | | | | | | | | | **cache line 4** | | | | | | | | | | | | | | | | | | **page fault?** | | | | | | | | | | | | | | | | --- **Explanation**: In the table provided, there are four cache lines available for storing pages. The sequence of pages that need to be loaded into the cache is given across the top row (1, 2, 3, 4, 5, 7, 9, 3, 1, 4, 2, 6, 7, 9, 5). **Purpose**: - Determine the number of page faults using three different page replacement algorithms: Optimal (OPT), First-In-First-Out (FIFO), and Least Recently Used (LRU). - Calculate the miss ratios for each algorithm. **Key Terms**: - **Page Fault**: Occurs when a page needs to be loaded from memory because it is not
