WebRTC (Web Real-Time Communication) is an open-source technology that enables real-time audio, video, and data communication directly between web browsers or mobile apps.

How does WebRTC work?

WebRTC uses JavaScript APIs, STUN/TURN servers, and ICE (Interactive Connectivity Establishment) to establish real-time peer-to-peer (P2P) connections.

What is a TURN server in WebRTC?

A TURN (Traversal Using Relays around NAT) server helps relay media traffic when peer-to-peer (P2P) communication is not possible due to strict NAT or firewall settings.

WebSockets is a full-duplex communication protocol that enables real-time data exchange between a client and a server.

What is the difference between WebRTC and WebSockets?

WebRTC is designed for peer-to-peer (P2P) real-time communication (video, audio, data), while WebSockets is a client-server protocol used for bidirectional communication (e.g., chat apps, live updates).
