WebRTC Preparation Practice Tests

WebRTC is an open-source technology that enables real-time communication capabilities directly within web browsers and mobile applications without requiring additional plugins or software installations. It provides APIs for peer-to-peer communication, allowing audio, video, and data sharing between users. This technology is supported by major web browsers, including Google Chrome, Mozilla Firefox, Safari, and Microsoft Edge, making it a widely adopted standard for web-based communication.

With its low-latency and high-quality transmission, WebRTC is commonly used in applications such as video conferencing, online gaming, telemedicine, and live broadcasting. One of the key features of WebRTC is its ability to establish direct peer-to-peer connections, reducing the need for intermediaries like servers for media transmission. This results in lower latency, improved performance, and reduced bandwidth usage, making it an efficient choice for real-time communication.

WebRTC achieves this through various protocols and standards, including the Interactive Connectivity Establishment (ICE) framework, which helps in establishing connections even in complex network environments. Additionally, it supports Secure Real-time Transport Protocol (SRTP) for encrypting audio and video streams, ensuring privacy and security. WebRTC is built with several core components that facilitate seamless communication.

These include the MediaStream API, which handles access to a device's microphone and camera, the RTCPeerConnection API, which manages the peer-to-peer connections, and the RTCDataChannel API, which enables direct data exchange between peers. These components work together to provide a complete framework for real-time interaction, allowing developers to build applications that can support high-quality voice and video calls, screen sharing, and instant messaging. Due to its flexibility, WebRTC is widely integrated into various platforms, including social media, enterprise collaboration tools, and customer support services.
