What is the difference between BSC address and BNB address?

Could you please elaborate on the distinction between a BSC address and a BNB address? I'm interested in understanding how they differ from each other and what specific functions or uses each one serves within the cryptocurrency ecosystem. Could you break down the key characteristics and features of both, and explain in detail why it's important to distinguish between them? I'm seeking a clear and concise explanation that will help me grasp the fundamental differences between these two addresses. Thank you for your assistance.
