5.16 As described in Section 5.7, virtual memory uses a page table to track the mapping of virtual addresses to physical addresses. This exercise shows how this table must be updated as addresses are accessed. The following data constitute a stream of virtual byte addresses as seen on a system. Assume 4 KiB pages, a four- entry fully associative TLB, and true LRU replacement. If pages must be brought in from disk, increment the next largest page number.

What would be some of the advantages of having a larger page size? What are some of the disadvantages? 5.16 As described in Section 5.7, virtual memory uses a page table to track the mapping of virtual addresses to physical addresses.
