Câu 2: In Disk Arm Scheduling Algorithms: Consider the seek to cylinder 71 is in progress; new requests come in for cylinders 1, 36, 16, 34, 9, and 12; A seek takes 6 msec per cylinder. Calculate Seek time with Shortest Seek First (SSF) algorithm?

Câu 3: In what scenario would a microkernel-based operating system structure be advantageous compared to a monolithic structure?

Câu 4: Which RAID level provides disk striping without fault tolerance?

Câu 5: Example of First-Come-First-Served (FCFS): Suppose that the processes arrive in the order: "P2, P3, P1". Calculate the Average waiting time of the processes with the following burst time: Burst Time of P1 process: 24, Burst Time of P2 process: 3, Burst Time of P3 process: 3.
