What does VoIP stand for, and what is its primary function?

Voice over Internet Protocol (VoIP) is indeed the correct term, and its primary function is to convert voice signals into digital data that can be transmitted over the internet. This technology enables voice communication to take place over IP networks, allowing users to make phone calls using an internet connection instead of traditional telephone networks.

By digitizing voice signals, VoIP effectively allows for the transmission of audio data in packets, making it possible to communicate seamlessly across various devices and platforms. VoIP enhances communication capabilities with features like video calling, conference calls, and integration with other internet-based services, which are not possible with conventional telephony.

The other options incorrectly define VoIP or describe functions that do not align with its primary purpose. For instance, 'Visual over Internet Protocol' suggests a focus on video rather than voice, while 'Virtual over Internet Protocol' implies creating networks rather than facilitating voice communication. Similarly, 'Voice operating Internet Protocol' is a confusion in terminology without accurately representing the technology's function.
