What is the commonly used method to transmit phone conversations over a digital network?

• A. VoIP
• B. Analog Telephone
• C. Email
• D. FTP

Answer: (A)

Phone conversations over a digital network are carried as voice data that travels as packets over an IP network. This approach, called VoIP, converts the spoken signal into digital data, encodes it with a codec, breaks it into packets, and uses the Internet Protocol to route those packets between endpoints. Signaling protocols (to set up and tear down calls) and real-time transport protocols (to manage timing and delivery) work together to keep the conversation in near real time, even if the network experiences some variability. The key benefit is that voice can ride alongside other data on the same network, often reducing costs and enabling easy integration with other digital services. An analog telephone relies on a traditional circuit-switched network and remains largely separate from IP data pathways. Email and FTP are designed for asynchronous text messaging and file transfers, not real-time voice communication.
