Do your employees spend too much time travelling? Do you want to eliminate the costs associated with it? Videoconferencing is the solution. Modern technology allows you to have nearly the same options during a virtual conference as during a traditional one.
Besides business, videoconferencing has other uses. One example is in schools: videoconferencing can allow students who are not able to attend in person, perhaps for health reasons, to connect to a lecture. One can watch the lecture either live or recorded.
