Software that lets someone take control of another user's computer in a distant location. Only keystrokes, mouse movement and screen changes are passed between the client "controlling" computer and host "controlled" computer. All application processing takes place in the host (see illustration below).Remote control is the only effective way support reps can troubleshoot serious problems with a user's computer in another location, and the Internet has made it simple. The software is installed at both ends, and both the user and the technician see the same screen and can run the machine. Remote control is also used to provide training to a remote user who can watch and imitate the actions on screen by the remote instructor. In addition, remote control provides a shared desktop that lets two users collaborate on drawings and other visual objects. Also called "remote access software," "remote desktop sharing," "desktop sharing" and "application sharing." See application sharing, Remote Desktop and VNC.
