If you manage more than one computer, you may have wanted, at one point or another, a “remote keyboard,” a “remote mouse,” and a “remote screen” for that far-away computer, even if it is just up or down the stairs in your house.
VNC (Virtual network computing) can help here. Think about it as your screen, a keyboard, and a mouse at a remote workstation, controlled via the network and quite usable in terms of speed, even on somewhat slower connections.
