Queues

Queues are a fundamental data structure in computer science, representing a linear collection of elements organized in a specific order. They operate on a First-In-First-Out (FIFO) principle, where the first element added is the first to be removed. This structure is widely used in various applications, such as task scheduling, breadth-first search algorithms, and managing resources in computing environments. Queues can be implemented using arrays or linked lists, and they support essential operations like enqueue (adding an element) and dequeue (removing an element). Understanding queues is crucial for efficient data management and processing in software development.
