Question

Explain the following term:

QUEUE

Answer 1

• A Queue is a linear data structure that follows the FIFO (First-In, First-Out) principle, meaning the first element added is the first one to be removed.
• It uses two primary operations: Enqueue (to add an item to the back) and Dequeue (to remove an item from the front). A common example is a line of people waiting for a bus.
