Is Binance Smart Chain the same as Binance?

Excuse me, but I'm a bit confused about something. Could you clarify the distinction between Binance and Binance Smart Chain for me? Are they essentially the same thing, or do they serve different purposes within the cryptocurrency landscape? I've heard about both, but I'm not entirely sure how they differ from each other. Could you please explain it in a way that's easy to understand? Thank you in advance for your help.
