The technology often used for facilitating peer-to-peer communication is WebRTC (Web Real-Time Communication). This technology enables audio and video sharing directly between browsers without the need for plugins or additional software. WebRTC is utilized in applications like video conferencing, online gaming, and real-time data sharing. By providing low-latency communication, it enhances user experience and enables seamless interactions between users across different devices and platforms, fostering real-time collaboration and connection.
