What does "Packing" mean when referring to the compression of digital data?
Calculate the seek-distance using the SSTF (shortest seek-time first) and C-SCAN algorithms given the following disc access schedule in terms of the cylinder number. Assume there are 100 cylinders in total; the head is currently in position 80; and the head is moving downwards.
