VNC (Virtual Network Computing) is a software package which serves as a medium of connection between a user client and a remote computer. It creates a session with the remote server, which allows us to treat the remote server as if it were our machine, access the GUI of the remote server, and interact with it using the mouse and keyboard as a normal user.
