Q4. ( 13 points) Consider a two-level memory system:

Level 1 is the main memory with access time = 50 ns & hit ratio = 0.9999998.

Level 2 is the hard disk with access time = 10 ms + the time needed to transfer a page from the disk to the main memory.

Data transfer rate (from disk to main memory) = 100000 bytes/second.

Average access time = 60 ns.

Find the size of the page in bytes.

V.I. Hint: you have to show in detail your own calculations
