The technology that enables synchronous communication between users in a video call is known as WebRTC (Web Real-Time Communication). This technology provides audio, video, and data sharing capabilities directly through web browsers without the need for additional software installations, facilitating seamless interaction between users. WebRTC leverages peer-to-peer connections to ensure low latency and high-quality communication. It has become essential for many video conferencing platforms, contributing to the rise of remote collaboration and virtual interactions in various fields, including education, business, and entertainment.
