What are the advantages of FCFS scheduling?

FCFS, or First-Come, First-Served, is a simple scheduling algorithm. Its main advantages include fairness, simplicity, and ease of implementation.

Can you explain how fairness works in FCFS?

In FCFS, every process is treated equally based on its arrival time. The first process to arrive is the first to be executed, ensuring no process is starved.

What about the simplicity aspect?

FCFS is straightforward to implement since it requires minimal overhead. There’s no need for complex algorithms or data structures.

Are there any downsides to using FCFS?

Yes, one major downside is the potential for the 'convoy effect,' where shorter processes wait for a long process to complete, leading to inefficiency.

How does FCFS compare to other scheduling algorithms?

Compared to algorithms like SJF or Round Robin, FCFS can be less efficient in terms of average wait time and turnaround time.
