20. Suppose you have a byte-addressable virtual address memory system with eight virtual pages of 64 bytes each, and four page frames. Assuming the following page table, answer the questions below:

a) How many bits are in a virtual address?

b) How many bits are in a physical address?

c) What physical address corresponds to the following virtual addresses? (If the address causes a page fault, simply indicate this is the case.)
i. 0x0 ii. 0x44 iii. 0xC2 iv. 0x80

Page # Frame # Valid Bit 0 1 1 1 3 0 2 0 34567 NO 1 2 1 0 0 0
