Remote Control SoftwareRemote control software is software designed to allow use of computers or other hardware that is far aware. A typical usage is to control a server or desktop computer from another desktop computer. Remote controlling is possible in two ways: Duplicate desktop The controlling computer receives a copy of the controlled computes screen image. The copy is updates regularly, for example after a certain time, or when a change on screen is notices by the remote control software. The software on the controlling computer watches keyboard and mouse activity. The actions is sent to the controlled computer, where the remote control software simulates these actions. The controlled computer should then behave as if the actions was performed directly at that computer. This method is most usable for support and education. Remote control combined with audio communication can be as helpful for novice computer-users as if the helping person was actually there. It can also be used for "headless computers". In stead of having several monitors and keyboards next to each other (one for each computer), or using a switch*), you can attach a single moniter, keyboard and mouse to one computer, and use that one for remote controlling the other computers. *) A computer switch: Connect one moniter, keyboard and mouse to the switch, connect each computer to the switch. Using the switch you can select which computer the monitor etc. should be connected to. Virtual desktops The controlling computer will work almost the same is with duplicating the desktop, but the actions of the controlling computer is probably almost unnoticeable on the physical screen. This way several people can use the same computer at once, without disturbing each others work. This could be usable for several administrators doing different tasks on the same server. It can also be used for using hardware attached to the controlled computer, without disturbing a person who may already be using the computer. If the controlled computer is powerful compared to the controlling computer, it can feel as if the controlling computer is a better computer. The controlling computer only need to be powerful enough to run the remote controlling software, therefor it can be a very simple and cheap computer. When you use such a "thin client" or "dumb terminal", you may not even know that your softare is actually running on another computer. In some cases it is cheaper to buy one large computer, and a bunch of thin clients or dumb terminals, that buying a complete computer for each workstation. If you already have enough computers, but they are not powerful enough, you may only need to buy one new computer, and then use the old ones as thin clients.
