In videoconferencing technology, two or more people at different locations can see and hear each other at the same time, sometimes even sharing computer applications for collaboration. Videoconferencing offers possibilities for schools, colleges, and libraries to use these systems for a variety of purposes, including formal instruction (courses, lessons, and tutoring), connection with guest speakers and experts, multi-school project collaboration, professional activities, and community events.
Placing a video call is a lot like placing a telephone call. After you connect, you see the other person in color video on a TV screen and may be able to transfer files or collaborate via options such as document sharing or white boarding.
