How do I receive an AirDrop?

Could you please explain to me in simple terms how I can receive an AirDrop? I'm a bit new to this concept and would like to understand the steps involved. Is it necessary to have a specific type of device? Do I need to enable any specific settings? Also, are there any safety concerns I should be aware of when receiving an AirDrop? Could you clarify these points for me? I appreciate your help in guiding me through this process.
