The technology crucial for enabling real-time communication in applications includes WebRTC (Web Real-Time Communication). WebRTC is a set of protocols that allows audio, video, and data sharing between browsers and applications without requiring additional plugins. This technology supports peer-to-peer interactions, enabling features such as video conferencing, live streaming, and instant messaging. By facilitating real-time communication, applications can enhance user engagement and provide instantaneous interactions, crucial for remote collaboration, customer support, and various interactive services. WebRTC empowers developers to create rich, real-time experiences for users in diverse contexts.
