Virtual Network Computing (VNC) is a remote access software that enables you to control a computer from a remote location. It allows you to view and interact with the desktop of another computer, as if you were sitting in front of it. The software uses a client-server architecture, where the VNC client runs on the remote computer, and the VNC server runs on the computer you want to control. You can connect to the remote computer using a VNC client on your computer or mobile device, and then use the mouse and keyboard to control it as if you were sitting in front of it. VNC is widely used for remote administration, remote support, and for accessing your own computer from another location.
