What is 1000SATS in Binance?

Could you kindly explain to me, in a straightforward manner, what exactly 1000SATS represents in terms of value on the Binance platform? I'm a bit unfamiliar with the intricacies of cryptocurrency and would appreciate a clear, concise answer to this question. Is it a specific amount of a particular coin? Or does it represent a fraction of a larger unit? I'm eager to learn more about this topic and your guidance would be greatly appreciated.
