The relation between Virtual addresses and physical memory ad- dresses is given by the page table. Every page begins on a multiple of 4096 and ends 4095 addresses higher so K-8K really means 4096-8191 and 8K to 12K means 8192-12287 * page and for an 8 KB page: 20000, 32768, 60000. Using the page table of Fig. 3-9, give the physical address corresponding to each of the following virtual addresses (a) 20 (b) 4100 (c) 8300 45. Explain the difference between internal fragmentation and external fragmentation. Which one occurs in paging systems? Which one occurs in systems using pure seg- mentation
