What type of technology is used with Voice over Internet Protocol (VoIP)?

  1. HD Audio

  2. Wi-Fi

  3. Multicasting

  4. Bluetooth

The correct answer is: Multicasting

Voice over Internet Protocol (VoIP) is a technology used for making and receiving telephone calls over the internet, rather than the traditional telephone network. Multicasting is the technology used with VoIP, allowing for communication between multiple devices on the same call simultaneously. HD Audio may be used for superior sound quality, but it is not the main technology behind VoIP. Wi-Fi and Bluetooth are also not directly related to VoIP technology and are mainly used for wireless data transfer rather than voice communication.
