What is Round Robin?
Round Robin is a simple and widely used scheduling algorithm that distributes tasks evenly across available resources. It works by assigning each task a fixed time slot in a circular order.
How Round Robin Works
- Resources are arranged in a circular list
- Each new request is assigned to the next resource in the list
- After the last resource, it wraps around to the first
