MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A Queue is a FIFO (First In First Out) data structure where the element that is added first will be deleted first. The basic queue operations are enqueue (insertion) and dequeue (deletion). Enqueue is done at the front of the queue and dequeue is done at the end of the queue.

Detailed explanation-2: -FIFO (First-In-First-Out) queues have all the capabilities of the standard queues, but are designed to enhance messaging between applications when the order of operations and events is critical, or where duplicates can’t be tolerated.

Detailed explanation-3: -The primary difference between Stack and Queue Data Structures is that Stack follows LIFO while Queue follows FIFO data structure type.

Detailed explanation-4: -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-5: -The data structure that implements FIFO is Queue.
