VNC – Virtual Networking Computing
Virtual Network Computing is a graphical desktop sharing system with which another computer or other computers may be controlled. It basically transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction.
VNC is platform-independent — a VNC viewer on any operating system usually connects to a VNC server or host on any other operating system. There are clients and hosts for many GUI-based operating systems. Multiple clients may connect to a VNC host at the same time. Popular uses for this technology include remote technical support and accessing files on one's work computer from one's home computer, or vice versa.
VNC was originally developed at the Olivetti Research Laboratory in Cambridge, United Kingdom. The original VNC source code and many modern derivatives are open source under the GNU General Public License.
VNC can be used in a school environment where teachers and students log in on their own computer and view either the schools computer or one of the students. Weekly meetings could be arranged for after school tutoring in a whole range of subjects including math and science.
How does it work?
To establish a connection between two computers is easily accomplished by making use of the free internet site www.showmypc.com This website shows a user how to be a host as well as a viewer. This website loads a small program on the host and client computer which allows host to communicate to the viewer(s) and vice versa.
The host computer will generate a password so client computers can log in over the internet.
Additionally, the host can choose whether clients have access to the keyboard and the mouse or not.
Once the host has set up his or her computer, clients can log into the host by going to the same website and choosing the client app. Once the app is run and the password is entered, the client sees the host computer.
To communicate between the host and clients, the host can set up a meeting room. At the bottom of this window, the host can actually use a rudimentary form of a white board to draw images if needed.
