This attempt took 15 minutes.
For the following questions, consider a paged memory system that has a
physical main memory size of 64KB (216) and a page frame size of 8KB
(213). Consider a process P whose logical address space is 64KB (216).
Important Note: If an answer requires an exponent, use the ^ character.
For example: 216 would be entered as 2^16.
Question 1 pts
How many physical page frames are there in the above paged memory
system? Your answer should be in exponential form. 2^3
How many bits are needed to represent a physical page frame number in
the system? 3
Answer 1:
2^3
Answer 2:
3
