Quick Answer

Also known as the Virtual Network Computing, VNC viewer is a graphical desktop sharing system or remote-control software which serves to give you the control of a computer over a network connection. With the program, you can gain access to and manage a server, desktop, or even servers from another computer that may not necessarily be in the same location as the other.

The technological world has grown in a very crazy way over the years, thanks to a lot of things including Remote Desktop Applications which serve to give you an experience of one computer while using another. With that, you can gain access to your desktop using your laptop even when you are in a different location entirely. That is what you get with a VNC viewer.

The interesting thing about the Virtual Network Computing System is that it is available for both Windows and Mac and you can as well use it on mobile devices. Nonetheless, the important thing to know is that because its system is platform dependent, it can only be connected to two systems using the same types of operating system.

The way VNC work is by transmitting the movements of your mouse and keyboard from a thin client computer to that of a large client computer. It makes use of the RFB protocol through which you can transmit screen pixel data from one system over a network to another and then send back commands (control).

While what you need is a VNC Server app for the remote computer that you want to control, a VNC Viewer app is needed for the computer that will do the controlling. This means that the two computers that are involved have to be connected through the VNC.
