Is BNB a bank?

Excuse me, but I'm a bit confused by the terminology. Could you clarify for me, is BNB a traditional banking institution, akin to the likes of JP Morgan or Bank of America? From my understanding, BNB refers to Binance Coin, which is a cryptocurrency used on the Binance exchange platform. It's not a physical bank with branches or a traditional financial institution that offers banking services, right? Am I misunderstanding something here? Could you elaborate further on the nature of BNB and how it differs from traditional banking?
