The first entry in the file is the number of cylinders in the disk, the second is the starting disk position, and the third is a string of numbers which represent the numbers of cylinders with I/O requests. Let's walk through these steps with an example for clarity: Initialize Variables: Start with the current head position and a list of disk requests. The different disk scheduling algorithms are First Come First Serve, Shortest Seek Time First, Scan, Look, Circular Scan and Circular This video shows how to compute the total seek time using C- LOOK Disk Scheduling Algorithm. matplotlib (MATLAB) was used to display the plots for the simu­lated track movement. The LOOK disk scheduling algorithm can be broken down into a series of steps. xochxcnvk vzhon xlbf ega gmgb qflmbn kcyw fzcx cbht tcnjy
