Is Binance a wallet or exchange?

Is Binance merely a wallet for storing cryptocurrencies, or is it primarily an exchange platform for trading digital assets? This question has been popping up quite frequently among the crypto community, and I'm quite curious to know the answer. If it's a wallet, then it must offer robust security features to safeguard users' funds. On the other hand, if it's an exchange, it should provide a seamless trading experience with a wide range of cryptocurrencies and trading pairs. Could you clarify this for me? I'm interested in understanding the functionalities and services that Binance offers to its users.
