(c) RAID 2 uses parity bit for error detection.

(a) RAID 3 uses byte-level striping with a dedicated parity disk.
#451202
(b) RAID 4 consists of bit-level striping with a dedicated parity disk.

(a) If the process is allocated 4 frames, the LRU algorithm incurs 10 page faults.
#451205
(b) If the process is allocated 6 frames, the optimal algorithm incurs 8 page faults.
#451206
(c) If the process is allocated 5 frames, the FIFO algorithm incurs 13 page faults.
#451207
(a) If the process is allocated 4 frames, the reference-bit algorithm incurs 15 page faults. Assume that we start searching from the frame next to the frame with the last brought in page. If the page last brought in is in the last frame, then we start searching from the first frame.
#451208
(b) If the process is allocated 5 frames, the -chance algorithm incurs 14 page faults. Assume that we start searching from the frame next to the fame with the last brought in page. If the page last brought in is in the last frame, then we start searching from the first frame.
