Pairing is the correct term for the process of establishing a secure connection between two Bluetooth devices. It often involves making one device discoverable while the other searches for it, and confirming a code or PIN that may be displayed on one or both devices. Bonding, on the other hand, refers to the creation of a relationship between two Bluetooth devices with stored link keys, allowing them to automatically establish a connection when in proximity, but this happens after the initial pairing. Tethering refers to sharing a device's internet connection with another device, which is not directly related to initiating a Bluetooth connection. Handshaking is a process in computer networking where mutual authentication occurs and session keys are established, but it isn't typically used to refer to the Bluetooth pairing process. Syncing typically refers to the exchange of data between devices, which may happen over a Bluetooth connection, but does not specifically describe the initial connection setup.
