The idea is pretty simple: it allows users to remotely control their desktop computer over the Internet. The user's mouse movements and keystrokes are transmitted to their desktop computer via a dedicated network channel using TCP/IP, ensuring secure communication. This channel operates on network port 3389. The user's desktop is then displayed on the computer they connect to, providing a seamless experience.
RDP is commonly used for various scenarios, such as accessing files, running applications, and printing documents on a remote PC without physically being present. It is not limited to personal computers but is also utilized in server or virtual server environments for business purposes.
To use RDP, the host device (the machine being controlled) needs to be turned on and remain powered on. Sleep settings may need adjustment to prevent the host computer from turning off. RDP is built into Windows machines and can be enabled by going to Settings > System > Remote Desktop. By default, the options to keep the PC awake for connections and make it discoverable on private networks are enabled.
Occasional slight delays may occur due to the encryption and transmission of keyboard and mouse inputs, as well as the display data. However, RDP provides a practical and secure solution for remote access to desktop computers, enhancing productivity and convenience.
