Question 1

What is the role of the valid bit in a page table entry?

  • It determines page size
  • It indicates if a mapping is legal
  • It specifies physical memory location

💡 Hint: What does it signal if the bit is set to 0?

Question 2

True or False: Segmentation allows for multiple segments within a single page table.

  • True

Challenge Problems

Push your limits with challenges.

Question 1

A process has a virtual address space of 2 GB with a page size of 4 KB. Calculate the number of entries in its page table and the total memory required for the page table assuming each entry is 4 bytes.

💡 Hint: Use division to find number of pages, then multiply by size of each entry.

Question 2

Discuss how the integration of paging into segmentation helps with memory efficiency, providing examples based on your understanding.

💡 Hint: Think about how segments and pages can work together for dynamic memory allocation.
