1. Consider a system that uses virtual memory and paging. There are 32 bytes of virtual memory and 8 bytes of physical memory. Page sizes are 2 bytes each. The CPU generates address 0x1D. Assume the partial page table is populated as shown below:

For A-D, use the Solutions offered below.

a. What virtual page number is referenced in this address? (in decimal) b. Does a page fault occur (yes/no) c. In which frame is the requested virtual page found? d. What is the final physical address of the requested byte?

Page	Frame	Valid
0	-	0
2	0	1
4	-	0
5	2	1
6	-	0
8	-	0
10	-	0
12	1	1
