A Queue represents a waiting line and follows the principle of "First In First Out" (FIFO) where the elements added first are the ones removed first. Hence, insertions are made at the back of the queue and removals are made from the front. This makes it a suitable data structure for modeling real-world scenarios, such as waiting lines in a store or a bank.
