VNC (Virtual Network Computing) is a tool initially developed by AT&T Laboratories Cambridge for visually operating a remote computer over the Internet.
VNC is a client-server program which, using with a VNC client, lets you view and control a remote system on which a VNC server has been opened. There are VNC clients and servers for a wide range of platforms (Windows, MacOS, Unix, Linux, etc.), so with a client running Windows, you can take control of machines running other operating systems.
VNC has many fields of use, such as performing administrative tasks on remote machines, online tutoring, and tech support.
