Consider the following string of page references: 7, 0, 1, 2, 0, 3, 0, 4, 2,...

Consider the following string of page references: 7, 0, 1, 2, 0, 3, 0, 4, 2, 3, 0, 3, 2. The main memory can only contain THREE frames. Show the frame allocation for: (60 points)

  1. FIFO (First-in-First-out)
  2. LRU (Least Recently Used)
  3. Clock
  4. Optimal (assume the page reference string continues with 1, 2, 0, 1, 7, 0, 1)
  5. List the total number of page faults and the miss rate for each policy. Count page faults only after all frames have been initialized.
