Problem $2$ Virtual Memory

Consider a multi$-$level memory management scheme with the following format

for virtual addresses:

Virtual Page #$1$ Virtual Page #$2$ Offset

$10$ bits $10$ bits $12$ bits

Virtual addresses are translated into physical addresses of the following form:

Physical Page # Offset

$20$ bits $12$ bits

Page table entries $($PTE$)$ are $32$ bits in the following format, stored in big$-$endian

form in memory $($i$.$e$.$ the Most Significant Byte is first byte in memory$).$
