Voice over Internet Protocol, commonly abbreviated as VoIP, refers to the technology that enables voice communication and multimedia sessions over the Internet. It works by converting voice into digital data packets, which can then be transmitted across the Internet, allowing for phone calls to occur without traditional telephony infrastructure. VoIP is used in various applications, from internet-based phone services like Skype to more traditional business communication systems.

The remaining options do not accurately represent what VoIP stands for. For instance, while "Virtual online Internet protocol" and "Voice over Interface protocol" suggest some connection to digital communication, they confuse or misinterpret the basic concept of voice transmission over the Internet. Similarly, "Video on Internet protocol" is misleading because VoIP specifically pertains to voice, not video. Therefore, B is the correct response as it precisely captures the essence of this important technology in modern communication.
