Can you give me an example of round-robin scheduling?

Sure! Round-robin scheduling is a method used in operating systems to manage processes. For example, if you have three processes, A, B, and C, each gets a time slice of, say, 10 milliseconds. The CPU will first execute process A for 10 ms, then switch to process B for 10 ms, and finally to process C for 10 ms. This cycle repeats until all processes are complete.

How does it handle process priority?

In standard round-robin scheduling, all processes are treated equally, meaning they have the same priority. However, variations exist where priority can be incorporated, allowing higher-priority processes to receive more CPU time.

What are the advantages of using round-robin scheduling?

Some advantages include simplicity, fairness, and the ability to handle time-sharing effectively. It ensures that all processes get a chance to execute.

Are there any disadvantages?

Yes, some disadvantages include the potential for high turnaround time and context switching overhead, especially if the time slice is too small.
