Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft that allows users to connect to and control a remote computer over a network. RDP enables a user to interact with a remote computer's desktop as if they were sitting in front of it, even if the remote computer is located in a different physical location.
A basic example of Remote Desktop is connecting your home laptop to your office PC so you can access files, run applications, print documents, etc. on that PC without going into the office. However, the host device does not have to be a PC. It is often a server or virtual server environment in many business use-cases.
