A queue is a linear data structure that follows the First In First Out (FIFO) principle. This means that the first element added to the queue will be the first one to be removed.
Queues are commonly used in various applications such as scheduling processes in operating systems, handling requests in web servers, and managing tasks in asynchronous programming.
Enqueue: Adds an element to the end of the queue.
Dequeue: Removes the element from the front of the queue.
CPU Scheduling: Queues are used to manage processes in operating systems, ensuring that each process gets a fair share of CPU time.
Print Spooling: Queues manage print jobs in a printer, ensuring that documents are printed in the order they were submitted.
Task Scheduling: Queues are used in task scheduling systems to manage and execute tasks in the order they were added.
Data Streaming: Queues are used to buffer data streams, ensuring smooth and orderly processing of data.
