Videoconferencing allows for face-to-face communication between two or more physically separate locations by transmitting video and audio. It can save money and time compared to travel, help build relationships, and enable communication in situations where in-person meetings are not possible. While videoconferencing has benefits like improved communication and reduced costs, it also faces limitations such as high initial equipment costs and quality issues due to network infrastructure and configurations. There are different types of videoconferences including point-to-point between two locations, point-to-multipoint connecting multiple sites, and multi-point conferencing using a control unit.
