Airplay allows people to wirelessly transmit audio and video from their iOS devices to nearby speakers and screens. The iOS device is considered the AirPlay “sender” and the speaker or TV is considered the AirPlay “receiver.”
Think of AirPlay as an invisible cable connecting your iOS device to the device you want to watch or listen on because that’s almost exactly the right analogy.
