What is Virtual Network Computing (VNC) and how does it work?
Virtual Network Computing (VNC) is a graphical desktop-sharing system that allows users to remotely access and control another computer over a network. It works by transmitting the keyboard and mouse events from the client computer to the server computer, and then sending the graphical screen updates back to the client. This enables users to interact with the remote computer as if they were sitting in front of it. VNC is platform-independent, meaning that it can be used to access computers running different operating systems, such as Windows, macOS, or Linux.
The VNC protocol is based on the Remote Frame Buffer (RFB) protocol, which is a simple and efficient protocol for remote access. When a user connects to a VNC server, the server sends the current screen image to the client, and then the client sends keyboard and mouse events back to the server. The server then updates the screen image and sends it back to the client, creating a seamless and interactive remote access experience. VNC is widely used in various industries, including IT, healthcare, and education, for remote technical support, training, and collaboration.
