What is FCFS Disk Scheduling?
First-Come, First-Serve (FCFS) is a disk scheduling algorithm that handles requests in the order they are received. It works by scanning the disk from one end to the other, serving each request in the order it is received.
Advantages of FCFS Disk Scheduling
- Easy to understand and implement
- Fairly efficient for systems with low I/O load
Disadvantages of FCFS Disk Scheduling
- Can lead to poor performance in systems with high I/O load and a mix of long and short requests
- Does not prioritize requests based on urgency or importance
