VNC (Virtual Network Computing) is a system that allows us to control another computer from a distance, in such a way, that if we are connected to a local network or Internet, we can use another PC with our keyboard and mouse, without worrying about the distance.
A program to control any computer remotely
It's only necessary to install a server application (Server) in the computer that is going to be controlled and a client application (Viewer) in the computer from which we are going to control the remote PC, type in the corresponding IP address and insert the password with which we will protect the connection.
With the free version of this application we can be capable of remotely controlling almost every operating system on the market (Windows NT 4, 2000, XP, Server 2003, Linux, Solaris, HP-UX, AIX,...), with the current Mac OSX and Windows versions limited to the paid product (Vista, Server 2008 and Windows 7).
Connect to your home PC from wherever you are around the world with your laptop or any other computer, without complicated configurations thanks to VNC.
