What type of network does "VoIP" refer to?

"VoIP" stands for Voice over Internet Protocol, which is a technology that enables voice communication and multimedia sessions over the internet. This technology converts analog voice signals into digital data that can be transmitted over IP networks. It allows users to make phone calls using the internet instead of traditional telephone lines, making it a cost-effective alternative for both individual and business communication.

The term encompasses various services and apps, such as Skype, WhatsApp calls, and traditional VoIP phone systems used by businesses. Understanding VoIP is crucial, as it represents a significant shift in how voice communication is delivered, improving accessibility and reducing costs.

In contrast, the other options do not represent established technologies or recognized terminologies in networking and telecommunications. The incorrect options mention visual, video, or virtual interpretations, which are not relevant to the function of VoIP as it specifically pertains to voice communication over the internet.
