What Is Round Robin in Data Structure?
Round Robin is a popular scheduling algorithm used in operating systems and computer networks. It is a preemptive algorithm that treats all processes equally and allocates them an equal amount of time, known as a time quantum or time slice. The main goal of the Round Robin algorithm is to provide fair and balanced execution among multiple processes or tasks.
How does Round Robin work?
The Round Robin algorithm works by assigning each process a fixed time quantum. The processes are then executed in a cyclic manner, where each process gets to execute for a specified time period before being interrupted and moved to the back of the queue. This ensures that no single process monopolizes the CPU’s resources for an extended period.
Advantages of Round Robin
- Fairness: Round Robin provides equal opportunities for all processes to execute, ensuring fairness.
- Efficiency: It ensures that every process gets a chance to execute, preventing any process from being starved.
- Low response time: Round Robin maintains a short response time by giving each process frequent access to the CPU.
- Simplicity: The algorithm is easy to implement and understand due to its straightforward nature.
Disadvantages of Round Robin
- Inefficient for long tasks: If there are long-running processes, they may need multiple rounds before completing their execution, causing delays for other processes.
- Inefficient for short tasks: Short tasks may be preempted frequently, leading to unnecessary overheads due to context switching.
Pseudocode Example
Below is a simplified pseudocode example of the Round Robin algorithm:
Initialize queue to store processes
Initialize time quantum (slice)
while queue is not empty:
process = dequeue a process from the front of the queue
execute process for time quantum
if process is not completed:
enqueue the process back to the end of the queue
Conclusion
Round Robin is a widely used scheduling algorithm that provides fairness and balance in executing processes. Although it has some limitations, its simplicity and effectiveness make it popular in various operating systems and computer networks.
By allocating equal time slices to each process, Round Robin ensures that no process hogs the CPU for an extended period, leading to efficient resource utilization. Its preemptive nature allows for better responsiveness and prevents any single process from monopolizing system resources.
If you are looking for a scheduling algorithm that prioritizes fairness and ensures efficient execution across multiple processes or tasks, Round Robin can be an excellent choice.

When it comes to implementing round-robin scheduling, choosing the right data structure is crucial for efficient and effective task management.
Round Robin Scheduling is a popular CPU scheduling algorithm used in operating systems. It is designed to provide fairness by dividing CPU time equally among all processes in the system. One key aspect of Round Robin Scheduling is the use of a particular data structure – the circular queue.
A circular list data structure is a type of linked list where the last element points back to the first element, creating a circular loop. This means that traversing a circular list can continue indefinitely without reaching an end. What is a Linked List?
Rotation is a fundamental operation in data structures that plays a crucial role in maintaining balance and optimizing various algorithms. In this article, we will explore the concept of right rotation, its implementation, and its significance. What Is Right Rotation?
A circular queue is a data structure that follows the FIFO (First-In-First-Out) principle. It is similar to a regular queue, but with a slight variation. In a circular queue, the last element is connected to the first element, forming a circle.
What Is Circular Data Structure? In computer science, a circular data structure is a type of data structure that allows elements to be connected in a circular manner. Unlike linear data structures such as arrays or linked lists, circular data structures have the last element connected to the first element, creating a loop.
A circular data structure is a type of data structure in which the last element is connected to the first element, creating a loop. This loop allows for efficient traversal and manipulation of the data. In this article, we will explore the concept of circular data structures and understand their importance in various applications.
A circular graph is a data structure that represents a collection of nodes or vertices connected in a circular manner. In this type of graph, each node is connected to its adjacent nodes, forming a closed loop or cycle. Circular graphs are often used to model relationships or connections between different entities.
What Is the Circular Linked List in Data Structure? A linked list is a data structure that consists of a sequence of nodes, where each node contains a reference to the next node in the sequence. In a circular linked list, the last node of the list points back to the first node, forming a loop or circle.
A circular linked list is a type of data structure in which the last node of the list is linked back to the first node. This creates a circular loop-like structure, unlike a traditional linear linked list where the last node points to null. Structure of a Circular Linked List
In a circular linked list, each node contains two fields – data and a pointer to the next node in the list.
