Queue

A queue is a collection of items arranged in a specific order, typically following the "first-in, first-out" (FIFO) principle. Imagine waiting in line at a checkout; the first person to arrive is the first served. In computing, a queue works similarly, where data or tasks are added (enqueued) at the back and removed (dequeued) from the front, ensuring orderly processing. Queues are used in various systems like printing, task scheduling, and traffic management, helping organize and manage resources efficiently by handling items systematically.
