All modes except ring mode allow the peek operations so that software can view the next element without actually popping it from the queue. This is done by reading from a different offset from the normal pop operation. All the same fields are read but the element is not actually popped off of the queue. This is useful for algorithms that need to know about the overall queue and head element to make decisions but have not yet decided to pop from the queue.
