The RTC in WebRTC stands for Real-Time Communications, which are offered directly on the web without any need for plug-ins or third-party software. The idea is to be able to share and stream video, audio and data in the most powerful fashion, directly in a web browser, thereby offering media rich exchanges. This lets you, for example, engage in video and audio conferencing in your browser without any third-party software.
