Detailed explanation-1: -The queue data structure follows the FIFO (First In First Out) principle, i.e. the element inserted at first in the list, is the first element to be removed from the list. The insertion of an element in a queue is called an enqueue operation and the deletion of an element is called a dequeue operation.
Detailed explanation-2: -A queue is a First-In First-Out (FIFO) data structure, commonly used in situations where you want to process items in the order they are created or queued. It is considered a limited access data structure since you are restricted to removing the oldest element first.
Detailed explanation-3: -The data structure that implements FIFO is Queue.
Detailed explanation-4: -In queue, we will follow first in first out principle for insertion and deletion of elements. Element with least priority will be deleted in a priority queue.
Detailed explanation-5: -A FIFO queue is a queue that operates on a first-in, first-out (FIFO) principle. This means that the request (like a customer in a store or a print job sent to a printer) is processed in the order in which it arrives.
