How It Works
The controlling computer displays a copy of the image received from the controlled computer's display screen. The copy is updated on a timed interval, or when a change on screen is noticed by the remote control software. The software on the controlling computer transmits its own keyboard and mouse activity to the controlled computer, where the remote control software implements these actions. The controlled computer then behaves as if the actions were performed directly at that computer. In many cases the local display and input devices can be disabled so that the remote session cannot be viewed or interfered with.
The quality, speed and functions of any remote desktop protocol are based on the system layer where the graphical desktop is redirected. Software such as VNC and others use the top software layer to extract and compress the graphic interface images for transmission. Other products such as Microsoft RDP use a kernel driver level to construct the remote desktop for transmission of data.
