What is VoIP?

• A. Voice over Internet Protocol - a technology that allows telephone calls to be made over LANs, WANs and internet
• B. Video over Internet Protocol
• C. A type of wireless network
• D. A chat protocol

Answer: (A)

VoIP means sending voice as digital packets over Internet Protocol networks. Instead of using traditional telephone circuits, your voice is converted into data packets and transmitted over LANs, WANs, or the internet, then reconstructed back into sound on the receiving end. This approach makes calls possible over existing data networks and often reduces costs while offering flexibility to reach anyone with internet access. The option that defines VoIP as Voice over Internet Protocol—a technology that allows telephone calls to be made over LANs, WANs and internet—captures this idea precisely. The other choices point to different things: video over IP is about video, not voice; a wireless network is a broader category; and a chat protocol is typically for text messaging, not voice calls.
