WebMar 30, 2024 · FCFS: FCFS is the simplest of all the Disk Scheduling Algorithms. In FCFS, the requests are addressed in the order they arrive in the disk queue.Let us understand this with the help of an example. Example: Suppose the order of request is- (82,170,43,140,24,16,190) And current position of Read/Write head is: 50 WebExample: First we design a Gantt Chart according to arrival time and burst time to follow FCFS. Now calculate Completion Time (CT) from Gantt Chart Now we calculate Turn Around Time (TAT) and as per the formula we know Turn Around Time (TAT)= Completion Time (CT) – Arrival Time (AT) We can also calculate Wait Time (WT) using the formula:
