What is the history of round-robin scheduling?

What is the history of round-robin scheduling?

Round-robin scheduling is a CPU scheduling algorithm that dates back to the 1950s. It was developed to ensure fair allocation of CPU time among processes.

Who created the round-robin scheduling algorithm?

The round-robin scheduling algorithm was first introduced by General Motors Research Laboratories in the 1950s as part of their time-sharing system.

How does round-robin scheduling work?

In round-robin scheduling, each process is assigned a fixed time slice or quantum. When a process's time slice expires, it is moved to the back of the queue, allowing the next process to execute.

What are the advantages of using round-robin scheduling?

The main advantages include simplicity, fairness, and the ability to handle time-sharing systems effectively.

Are there any disadvantages to round-robin scheduling?

Yes, some disadvantages include the potential for high turnaround time and context switching overhead, especially with a small time quantum.
