WebAnswer: Both scan the disk looking for cylinders (tracks) that match I/O requests. Scan goes to the end of the disk and then reverses to the beginning. Look stops at the last request, reverses direction and stops at the lowest number request (instead of going all the way to 0). C-Scan only servic... Webscheduling techniques like FCFS, SSTF, SCAN, LOOK, C -SCAN and C -LOOK along with some additional SCA N techniques like FSCAN, N -Step SCAN etc. are discussed.
