Audio video conferencing is a shorthand way of describing a virtual conference where no one has to leave her office to meet up with the rest of the group. A virtual conference may use telephones, televisions, computers, conferencing software, collaborative software, file sharing, headsets, the Internet, or any combination of these equipments and tools. Slide presentation, streaming audio, and document sharing are some of the extras you can incorporate into this conferencing method.
