Assume we have a program that resides in the memory range of 80088000-810F0F00. The numbers are in hexadecimal. Virtual addresses are 32 bits and the system applies three-level hierarchical paging where the address division scheme is: 8-8-8-8 in which 8bits are reserved for offset a) What is the page size (in Byte)? b) How many entries are there in the 1st level page table? c) How many 1st level page table is needed? d) How many 2nd level page table is needed? e) How many 3rd level page table is needed? f) How much memory space can be mapped by one 3rd level page table (in KB)? g) What is the size of the program in the memory (in KB)? h) How much memory space is needed to store page tables? (Assume each entry in page tables is 4 byte)
