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

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 4K-8K really means 4096-8191 and 8K to 12K means 8192-12287
