Queue Data Structure in Computer Science #dsa #softwareengineering #computerscience #shorts

A queue is a linear data structure in computer science that follows the FIFO (First In, First Out) principle, meaning the first element added is the first removed. Elements are inserted at the rear using an enqueue operation and removed from the front using a dequeue operation. Queues are commonly used in operating systems, networking, and algorithms where tasks must be processed in order. Examples include printer task scheduling, handling web server requests, and Breadth-First Search (BFS) traversal in graphs. Queues can be implemented using arrays or linked lists and may include variations such as circular queues, priority queues, and deques.
