(Modified from a presentation I gave a few years back...)
The scenario is my wife is preparing food for us to eat for dinner. I am waiting wondering when food will be ready. With polling, I continuously bother her, asking, "when will food be ready?" With events, I can ask her to tell (notify) me, when food is ready, and I'll either take a nap (sleep) or play a video game (process something else).

It clearly explains the concepts and their applications, making it easier to understand the technical distinctions. For students in Canada who need to write essays on such complex topics, using an essay writing service in canada can provide the necessary support to craft well-informed and articulate essays.
