What technology is necessary for students to interact with an author over the Internet?

To facilitate interaction between students and an author over the Internet, Voice over Internet Protocol (VoIP) is the most suitable technology. VoIP allows for real-time communication through voice, enabling students to have a conversation with the author directly, whether that is through phone calls or internet-based voice chats. This technology is designed specifically for transmitting voice communications over the Internet, creating an effective means for dialogue.

While video conferencing could also be a viable technology for interaction, making it possible for face-to-face conversations through video, it relies on additional equipment and bandwidth. Virtual reality software typically focuses on immersive experiences and doesn't inherently provide the direct communication capability required for this type of interaction. Streaming media services are primarily used for broadcasting content but do not facilitate real-time communication between individuals. Hence, VoIP stands out as the most direct and practical choice for enabling students to interact seamlessly with authors online.
