This is my problem that I come across for most sites:
STACK
"Definition: A collection of items in which only the most recently added item
may be removed. The latest added item is at the top. Basic operations are
push and pop. Also known as "last-in, first-out" or LIFO. "
And my response: "Okay, great! What do you use it for?" or "So what?" This
simply says what a stack is, but nothing more. What would you push or pop?
And why would you? The only "data structure" that I get is the queue, and
only in one context: mouse clicks. You point and click on several items in a
sequence, and the queue processes them in the order that you clicked them.
