They are widely used for virtual classes, webinars and administrative meetings. ICT infrastructure such as cameras, microphones and bandwidth are essential. Hence, the meetings described are called video conferencing.

Option C:
Option C, text chatting, offers real time communication but usually without integrated audio visual components.
Option D:
