Technology that allows for real-time communication over the web includes WebRTC and various VoIP applications. WebRTC (Web Real-Time Communication) is an open-source project that enables audio, video, and data sharing directly between browsers. This technology reduces latency and allows for seamless peer-to-peer connections, making it suitable for video conferencing and online collaboration. Other platforms like Zoom and Slack utilize similar technologies to provide instant messaging and video capabilities for enhanced communication.
