PreviousGiven five memory partition of 100 KB, 500 KB, 200 KB, 300 KB, and 600 KB(in order), how would the first-fit and best-fit algorithms place processes of 212 KB, 417 KB, 112 KB, and 426 KB (in order)? Which algorithm makes the most efficient use of memory?NextSuppose that a disk drive has 5000 cylinders, numbered 0 to 4999. The drive is currently serving a request at cylinder 143, and the previous request was at cylinder 125. The queue of pending request, in FIFO order, is: 86, 1470, 913, 1774, 948, 1509, 1022, 1750, 130 Starting from the current head position, applying Shortest-seek-time-first algorithm find what is the total distance (in cylinders) that the disk arm moves to satisfy all the pending requests.
