Video conferencing software is primarily underpinned by VoIP (Voice over Internet Protocol) technology, which enables audio and video communication over the internet. This technology compresses and transmits voice and video data in real-time, allowing for clear and efficient communication between users. Additionally, advancements in bandwidth and compression algorithms have significantly improved the quality and reliability of virtual meetings. The integration of features like screen sharing and chat functionality enhances collaboration among participants, making video conferencing invaluable in remote work environments.
