Real-time communication in applications is enabled primarily by WebRTC technology. WebRTC (Web Real-Time Communication) allows audio, video, and data sharing directly between browsers and devices without requiring external plugins. This technology supports peer-to-peer connections, facilitating real-time interactions for applications like video conferencing, online gaming, and collaborative tools. By providing low-latency communications and seamless integration with web applications, WebRTC empowers developers to create rich and engaging user experiences in real time.
