Virtual Network Computing (VNC) is a technology that allows users to remotely control another computer over a network. It works by transmitting the keyboard and mouse inputs from the user's device to the remote computer, while sending back the graphical display of that computer to the user's screen. This enables users to access and manage their computers from different locations. VNC is platform-independent, meaning it can be used across various operating systems, such as Windows, macOS, and Linux. It is commonly used for remote technical support, accessing files, and managing servers, making it a valuable tool for both individuals and businesses.
