In a machine using 16 bit addresses and page size is 512 addresses, what's the maximum size for a process that executes?

Question

Since its 16 bit addresses and page size of 512 addresses, I think that makes the page offset 9 bits (512 is 2⁹) and the number of pages is 2¹⁶ - 2⁹ = 2⁷. What is the maximum size for a process that executes on this machine without the use of page demanding? In a process of size 4,535 words, what is the total memory that must be allocated to the program and how much fragmentation is there? Any suggestions? Thank you.

Answer 1

The maximum size of the process 2^16, or 65,536 words.

For the process size of 4535, the memory needed be 4608 (512 * 9) with fragmentation of 73 (4608 - 4535).
