What does VoIP stand for?

VoIP stands for Voice over Internet Protocol. This term refers to the technology that enables voice communication and multimedia sessions over the Internet using packet-switched protocols. By converting voice signals into digital data packets, VoIP allows for efficient transmission over internet networks.

Understanding this concept is crucial in the context of telecommunications and networking, as VoIP applications are widely used for internet-based communication services such as Skype, Zoom, and various business telephony systems. The other choices do not represent widely recognized terms in the field; they either misidentify the type of communication (like video or visual) or use incorrect terminology that doesn't align with standard industry definitions.
