Is BSC and Binance the same?

Could you please clarify for me? Are BSC and Binance interchangeable terms, or do they refer to distinct entities within the cryptocurrency sphere? If they're not the same, could you elaborate on the key differences between them? And if they are somehow related, how does that relationship work? Additionally, I'm curious to know if BSC stands for a specific acronym or term in the crypto world. Thank you for your assistance in clarifying this matter.
