Virtual Network Computing (VNC) is a remote desktop sharing technology that allows you to control another computer over a network or the internet. It works by transmitting the keyboard and mouse inputs from your device to the remote system, while also displaying that system’s screen in real time on your device. VNC is platform-independent, meaning it can be used across Windows, macOS, Linux, and more, making it useful for tech support, remote work, or accessing files and programs from afar. It typically requires a VNC server on the remote machine and a VNC viewer on the accessing device.
