Is Binance a dex?

Could you please clarify for me whether Binance qualifies as a decentralized exchange, or a dex, in the cryptocurrency ecosystem? I've heard conflicting information about this, and I'm curious to know if Binance truly offers the decentralized features and functionalities that are associated with dexes. Additionally, if it's not a dex, could you explain what type of exchange Binance actually is and how it differs from a traditional dex? Thank you for your assistance in clarifying this matter for me.
