A circular linked list is a linked data structure where the nodes are connected in a circle, meaning the last node points back to the first node, forming a continuous loop. This structure allows for efficient traversal from any node and is particularly useful in applications requiring a cyclic iteration over elements, such as round-robin scheduling.

Round-robin scheduling is a pre-emptive CPU scheduling algorithm where each process is assigned a fixed time slot in a cyclic order, ensuring that all processes get an equal share of the CPU time without starvation. It is particularly effective in time-sharing systems, providing a balance between throughput and response time, but can be inefficient if the time quantum is not optimally set.
