 What is a queue?

 It’s a structure that conforms to the principle of First In, First Out (FIFO).  The first item to join the queue is the first item to be served.

 What is a stack?

 It’s a structure that conforms to the principle of Last In, First Out (LIFO).  The last item to join the stack is the first item to be served.

 What is a heap?

 The heap property: If A is a parent node of B then the key of node A is ordered with respect to the key of node B with the same ordering applying across the heap
