title: What is page table No (0 or 1 or 2) in 2-level paging?
body: <blockquote>
  <p>A system with 2-level page table in the form of (p1, p2, offset), and the content of <strong>page table
  No 1 of level 2</strong> is: {(32, v),(45, i),(12, v),(5, v),(34, i)}. Suppose the frame size is 4KB; the
  address register is 32 bit, the number of bits for level 2 (p2) of the address register is 10.
  Given a reference =4225332, calculate its physical address, e.g., 12764?</p>
  </blockquote>
  <p>I don't understand the meaning of <strong>page table No 1 of level 2</strong>. In some problems, it could be No 0 or No 2. Could you help me explain that and solve this problem? Thanks a lot!</p>
