AirDrop is a feature available on Apple devices that allows users to share files wirelessly. It uses Bluetooth and Wi-Fi to create a direct connection between devices, enabling quick and easy transfer of photos, documents, and other content without needing an internet connection. To use AirDrop, both the sender and receiver must have the feature enabled on their devices. Users can choose to share files with everyone nearby or limit sharing to their contacts. This makes AirDrop a convenient option for sharing information in various settings, such as at work or during social gatherings.
