RDP is a proprietary protocol that provides a user with a graphical interface to connect to another computer. It uses a client-server model, wherein the computer being controlled is the server, and the device making the connection is the client. When a user initiates an RDP session, the client device sends various input commands (like keyboard strokes and mouse movements) to the server, which then processes these and sends back the corresponding graphical output. This real-time communication occurs over the TCP/IP network, typically using port 3389, although it can be configured to use different ports.
