Step-by-step explanation:
The technology that enables voice command and multimedia sessions over the internet is VoIP (Voice over Internet Protocol). VoIP has revolutionized the way we communicate by allowing phone calls to be made via the internet instead of using traditional phone lines. This innovation relies on various improvements in technology, such as microwave transmission and communications satellites, to transmit data quickly and reliably. Users benefit from more consumer choice, cheaper calls, especially long-distance, and often better-quality service. Technologies like Bluetooth and Wi-Fi also facilitate wireless communications for a multitude of devices and applications.
