The technology employed for online video conferencing is real-time communication (RTC) technology, often utilizing protocols such as WebRTC. This technology enables audio, video, and data sharing in real-time over the Internet, making it foundational for video conferencing tools like Zoom, Microsoft Teams, and Google Meet. RTC allows users to engage in face-to-face communication regardless of geographic location. The seamless integration of video and audio streams, combined with features like screen sharing and chat, enhances collaboration in various settings, including business and education.
