                 Video Conferencing

                 Video conference is a live virtual meeting held between two or more geographically separated
                 people. Each participant requires a video camera, a microphone, speakers and a high-speed
                 Internet connection to transmit audio and video data. As a participant speaks, members of
                 the meeting hear his voice on their speakers. Anything in front of his camera, such as his face,
                 appears in a window on each participant’s screen. Video conferencing is used in businesses
                 to conduct meetings or online classes for students located anywhere in the world, and in the
                 healthcare industry by doctors to interact with patients and colleagues. Examples of applications
                 that support video conferencing are Google Meet, Skype and Zoom.
