Consider a memory system with the following characteristics: Physical main memory size = 1KB (210) Page frame & page size = 256 Bytes (28) . . • System uses demand paging • Maximum logical address space size=4KB (2¹2) QA: How many physical page frames does this memory system have? Your answer must be in exponential form (use the form a^b). QB: How many bits are needed to represent the physical page frame number? QC: How many bits are needed to represent the offset within a physical page frame? Consider a process P1 that has an address space of 4KB (2¹2). QD: How many logical pages are there in P1's logical address space? Your answer must be in exponential form (use the form a^b). QE: How many bits are needed to represent a logical page number in P1's logical address space? Consider a process P2 that has an address space of 2KB (211). QF: How many logical pages are there in P2's logical address space? Your answer must be in exponential form (use the form a^b). QG: How many bits are needed to represent a logical page number in P2's logical address space?

Assuming that P1 issues the logical address Ox BDB. QH: What is the logical page number contained in the above logical address? Your answer must be in hexadecimal and must include Ox at the beginning. Do not include any spaces. QI: What is the physical page frame number corresponding to the logical page number identified in QH? If the page frame is not currently in the main memory, simply specify a dash (-) as your answer. Otherwise, your answer must be in hexadecimal and must include Ox at the beginning. QJ: What is the physical address corresponding to the logical address issued above? If the page frame is not currently in the main memory, simply specify 'N/A' as your answer. Otherwise, your answer must be in hexadecimal and must include Ox at the beginning. Do not include any spaces.
