Operating System It is known that a disk drive has 256 cylinders, with the number cylinder starts at 0 and ends at 255. The position of the needle on the disk drive currently stops at point 128. It is also known that the needle always “goes to the cylinder with the smaller number first”. The order of the positions visited sequentially is: 254, 64, 32, 100, 50, 70. Of the 3 choices of algorithms below, which one is the best algorithm? Make each image and determine the seektime.a. SCANb. C-SCANc. FIFO
