Challenge Problems

Push your limits with challenges.

Question 1

Analyze a system where a process's virtual memory usage grows from 1MB to 16MB requiring memory management strategies to address potential fragmentation. Propose a solution involving page table structure.

💡 Hint: Consider how different segments interact and the role of valid bits and length registers.

Question 2

Given a virtual address space of 4GB and a page size of 8KB, determine the number of page table entries and the required memory size for these entries.

💡 Hint: Use the total address space divided by the page size to find the number of entries first.
