        **What is WebRTC?**

        WebRTC (Web Real-Time Communication) is an open-source project and protocol that enables real-time audio, video, and data sharing directly between browsers and devices without the need for plugins or additional software.

        **Why is WebRTC useful?**

        * Enables peer-to-peer communication for video calls, voice calls, and data sharing.
        * Eliminates the need for intermediary servers for media traffic, reducing latency.
        * Built into modern browsers, so no installation is required.
        * Supports secure, encrypted communication.

        **How it works?**

        * WebRTC uses signaling (via external servers) to exchange session information.
        * It performs NAT traversal with ICE, STUN, and TURN protocols.
        * Peers establish a direct connection to share media streams or data channels.
        * Media streams are encoded, transmitted, and decoded in real-time using codecs.
        * Encryption is applied to ensure privacy.

        **Where is WebRTC used?**

        * Video conferencing apps (e.g., Google Meet, Zoom Web client).
        * Real-time chat and collaboration tools.
        * Live streaming and broadcasting platforms.
        * File sharing applications.
        * IoT device communications.

        **Which OSI layer does this protocol belong to?**

        * WebRTC operates mainly at the Application Layer (Layer 7).
        * It relies on lower layers (Transport and Network) for data transmission.
        * It also involves protocols like ICE/STUN/TURN for connection management.

        **Is WebRTC Windows specific?**

        No.
        * WebRTC is platform-independent.
        * Supported on Windows, macOS, Linux, Android, iOS, and browsers on all these platforms.

        **Is WebRTC Linux specific?**

        No.
        * WebRTC is not Linux specific.
        * It runs on any platform with compatible browsers or WebRTC implementations.

        **Which Transport Protocol is used by WebRTC?**

        * WebRTC uses UDP primarily for real-time low-latency media transport.
        * TCP is used as a fallback if UDP is blocked.
        * Data channels can use SCTP over DTLS for reliable data transport.

        **Which Port is used by WebRTC?**

        * WebRTC uses dynamic ports negotiated during session setup.
        * It typically uses UDP ports 1024-65535 for media.
        * STUN and TURN servers commonly use ports 3478 (UDP/TCP).

        **Is WebRTC using Client server model?**

        * WebRTC primarily uses a peer-to-peer model for media and data exchange.
        * However, signaling (session setup) requires servers.
        * TURN servers may be used to relay traffic when direct peer-to-peer connectivity fails.
