Which technology allows users to communicate over the Internet rather than through traditional public networks?

• A. CAD
• B. GPS
• C. Network
• D. Internet Telephony

Answer: (D)

This question is about technologies that carry communication over the Internet rather than through traditional telephone networks. Internet Telephony uses the Internet to transfer voice and other media as data packets, enabling calls over IP networks. This is often referred to as VoIP (Voice over IP). It bypasses the traditional public switched telephone network (PSTN), letting users communicate via broadband or other Internet connections, typically with different pricing and flexibility. CAD is computer-aided design, a tool for creating engineering drawings and models, not for sending messages over networks. GPS is a satellite-based navigation system that provides location data, not communication. A network is a broad term for interconnected devices, but it doesn’t specify a technology that carries calls over the Internet itself. Internet Telephony is the option that specifically enables communication over the Internet, making it the best fit.
