    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.
