The technology that enables real-time communication through the internet is known as WebRTC (Web Real-Time Communication). It is an open-source project that provides web applications and websites with real-time communication capabilities via simple application programming interfaces (APIs). This technology facilitates voice calling, video chat, and data sharing directly between browsers without needing plugins or additional software. Its low latency, high-quality audio, and video communications are beneficial in various applications, ranging from online conferencing to real-time collaborative tools.
