Question D.4: FIFO Page Replacement Consider the following page reference string: e, c, b, e, a, g, d, c, e, g, d, a Considering 4 frames, fill in the following table and then answer how many page faults would occur with the FIFO page replacement algorithm. RS: reference string; FO: frame 0, F1: frame 1, etc. Hint: all frames are initially empty, so your first unique pages will all cost one fault each. Time 1234567891011 12 RS e cb e agd ce g d a FO F1 F2 F3 Page fault? b) Total # page faults: c) Briefly (1-2 sentences) explain Belady's Anomaly that can occur in FIFO Page Replacement.
