Question 1 : Suppose I need 10 bits to specify the offset within a page and 22 bits to specify the virtual page number and 18 bits to specify the physical page number.

How big is a page in bytes?

How big is the virtual memory address in bits?

How big is the physical address in bits?

Question 2 : A system has a 46-bit virtual address. 24-bit physical address, and 2^20 Bytes of main memory. If the page size is 2⁹ = 512 bytes answer the following questions:

How many virtual pages are there?

How many physical pages will the system support?
