Computer and home networks are becoming more and more popular. Every adult has a laptop, children have game computers; computer-based media-centers are also becoming a common thing. Some advanced users go even further: old jokes about married couples that communicate over e-mail or instant messengers have become a reality :)
Moving from one PC to another takes too much time and distracts from the main objective. Also please note that your favorite and the most ergonomic and smooth mouse in the world, as well as the most modern and multi-functional multimedia keyboard are connected only to one computer. In light of this, using any other computer can make you feel uncomfortable and uneasy. That is why working with other computers without leaving your own favorite chair and tuned PC makes a lot of sense. It becomes even more reasonable when the remote PC you need to manage is located on other floor, or in another building or even in another country.
We often need to install software on several computers. For example, you might install the latest antivirus utility or database on your laptop, your wife's laptop and your child's games computer...oh (I almost forgot!) and to the family media-center in the living room. What would you suggest in such situation? Copy the software to a diskette and go to every machine? It is so tiresome and boring, besides, I don't recall my wife's laptop even has a disk drive!
The modern solution looks like this: from your PC you connect to other computers using Remote Desktop Control software. You can connect to one computer at a time or simultaneously connect to all of them. Simply run the installation file in every machine, and that's all! You won't even have to leave your cozy chair :)
