Remote Desktop is software that allows a user to remotely access and control application on some other system on the internet. Just the way it is possible to use a remote control to control electronic devices at your home (like your television, air conditioner, music system and others), remote desktop software is like a remote control to some others system on the internet.

Remote desktop software usually works by transmitting images of the controlled computer to the controlling computer at period intervals of time. It is almost like a live video feed of the controlled computer being watched on the controlling computer. The controlling computer can also control the controlled computer using their mouse and keyword. Typically, remote desktop tools are used by the technical helpdesk of a company or manufacture to diagnose and fix technical issues on the controlled computer. Remote Desktop tools can also be used by users to access their home computer from your collages or company remotely. Most importantly, they can also be used to bypass blocking mechanisms and access blocked website and applications.

If you are working for a company or studying in a collage, then chances are that they would have blocked access to all your favorites’ websites on the internet (like Facebook, YouTube and Google Talk, Skype and others) and even blocked applications like instant messengers. However, if you still want to access those blocked websites and applications from your office or collage computer then Remote Desktop Software can be very useful.
