What technology enables remote collaboration in video conferencing?

WebRTC (Web Real-Time Communication) is the technology that enables remote collaboration in video conferencing by facilitating real-time audio, video, and data sharing between browsers and mobile applications without the need for external plugins. It provides the necessary tools for peer-to-peer communication, making it ideal for video conferencing applications that require low-latency interactions and high-quality media transmission.

WebRTC combines multiple protocols such as STUN (Session Traversal Utilities for NAT) and TURN (Traversal Using Relays around NAT) to handle network traversal and maintain connections between devices behind firewalls or NATs. This technology allows seamless communication across different platforms and devices, enhancing the experience of virtual meetings and collaboration.

In contrast, Bluetooth technology focuses on short-range wireless communication primarily between devices, making it unsuitable for internet-based video conferencing. WebSocket protocol does enable real-time communication but is not specifically tailored for streamlined video/audio exchanges like WebRTC. FTP (File Transfer Protocol) is designed for transferring files over the internet and does not provide real-time media streaming capabilities, rendering it irrelevant for remote video collaboration.
