Queue

Do you want to understand how data is managed in a systematic order? In Computer Science – Class XII, Chapter “Queue” from NCERT, you explore an important linear data structure that works on the First-In-First-Out (FIFO) principle. You discover how real-life situations like bank counters and petrol pumps follow the same concept. This quiz helps you clearly understand how ordered processing works in computing.
As you study the FIFO concept, you realise that the element inserted first is removed first. You learn about the two important ends of a queue — Front and Rear. This strengthens your logical thinking and builds clarity about how data flows step by step.
When you explore queue operations like enqueue, dequeue, peek, isEmpty, and isFull, you understand how insertion and deletion are controlled. You also learn about special situations like Overflow and Underflow. This improves your analytical thinking and problem-solving ability.
