What is a maker fee taker?

Could you please elaborate on the term "maker fee taker" in the context of cryptocurrency trading? I understand that it relates to fees associated with transactions, but I'm not quite clear on the specific distinction between a Maker and a taker in this scenario. Are these roles assigned to traders based on their actions, and if so, how do they impact the trading fees they pay? Additionally, could you provide an example to help clarify the concept? Thank you.
