For a computer, you are given the following parameters, Main Memory Access Time: 75 ns

Effective memory access time in the absence of paging (computed by considering the main memory access time and the L1-cache): 7 ns

TLB access time: negligible

TLB hit ratio: 95 % 

There is NO virtual memory.

i.) Assuming a single-level page table, what would be the effective memory access time with paging enabled? Give the main steps of your derivation in a few lines.

ii.) Assuming a 2-level page table, what would be the effective memory access time with paging enabled? Give the main steps of your derivation in a few lines.
