VNC is a remote control application that proves to be useful for users that want to help other people with their computer by establishing a connection between the two devices. However, it can also serve for teaching purposes and it can be used to control a server from another location. The tool can be installed with ease and must be present on both computers in order for the connection to be established.

VNC uses a secure authentication method and users have to provide their login credentials so that they can access the other computer. After the connection is set up and users stat the remote control session, they can work with the other computer just as it would be their own. This is because a virtual desktop will appear, containing all of the elements present on the target computer.

With the aid of VNC, users can forward keyboard shortcuts and they can also use the Internet for different tasks. They can access more functions through the toolbar that is located at the top of the virtual desktop. File transfer can also be achieved and it is quite an easy task to do, because users just have to drag and drop files from one desktop to the other.
