Remote Desktop Protocol (RDP), developed by Microsoft, is a proprietary protocol that enables users to connect to a remote computer over a network, and access and control its resources, as if they were using the computer locally. This is useful for users who need to work remotely, manage servers or troubleshoot issues on another computer.

How RDP Works

RDP uses a client-server architecture, where the remote computer being accessed acts as the server and the user’s computer acts as the client. The client establishes a connection with the server to access its resources, such as display, keyboard, mouse, and other peripherals.

The protocol primarily operates on standard Transmission Control Protocol (TCP) port 3389 (although it can be customized) and uses the User Datagram Protocol (UDP) to provide a more robust and fault-tolerant communication channel.
