VNC, which stands for Virtual Network Computing, is a remote desktop sharing system that allows a user to control and interact with a computer workstation or server located remotely. It enables users to view and operate one computer's graphical interface and applications from another computer using a network connection.
In essence, VNC functions as a server-client software combination. The computer being controlled is referred to as the server, while the computer controlling it is called the client. Both computers must have the compatible VNC software installed to establish a connection.
The VNC server captures the display from the remote computer and transfers it to the VNC client over the network. This allows the client to display the remote desktop and sends any input from the client's keyboard or mouse back to the server. The server processes this input and responds accordingly, enabling the user to control and manipulate the remote computer as if they were physically present.
VNC employs a remote framebuffer (RFB) protocol that enables the client and server to communicate with each other. The RFB protocol defines the standard format for transmitting keyboard and mouse events, as well as graphics updates between the client and server.
VNC provides a convenient solution for remote support, collaboration, and access to resources on remote machines. It is widely used by IT professionals, system administrators, and individuals who require remote access and control of computers located elsewhere.
