      Question

      A system uses a 32-bit logical address space and a page

      size of 4KB. If each page table entry (PTE) is 4 bytes, how many entries can a single-level page table contain?
      A 2^10 Correct Answer Incorrect Answer
      B 2^12 Correct Answer Incorrect Answer
      C 2^20 Correct Answer Incorrect Answer
      D 2^22 Correct Answer Incorrect Answer
      E 2^32 Correct Answer Incorrect Answer

      Solution

      Logical address space = 2^32 bytes. Page size = 4KB = 2^12 bytes. Number of pages = 2^32 / 2^12 = 2^20. Each page corresponds to one entry in the page table.
