Remote Desktop Protocol (RDP) is a proprietary technology developed by Microsoft that allows two computers to exchange a graphical user interface (GUI) using a standardized network connection. It is a protocol or technical standard for remotely accessing and controlling a desktop computer. While there are other protocols available, RDP is the most commonly used protocol for remote desktop access.
RDP enables users to connect to a remote computer and interact with its desktop as if they were physically present in front of it. This means that users can access files, run applications, and perform tasks on the remote computer just as they would on their local machine. It provides a seamless way to work remotely or provide support and assistance to others remotely.
How Does Remote Desktop Protocol (RDP) Work?
Remote Desktop Protocol works by establishing a connection between a client and a server. The client is the computer from which the user wants to remotely access and control the desktop, while the server is the computer that the user wants to connect to. The server computer must have the RDP software installed on it.
When using RDP, input signals from the client’s keyboard and mouse are sent over the internet to the server. The server processes these signals and sends back display signals, allowing the client to see and interact with the remote desktop. The communication between the client and server is done through the Transmission Control Protocol (TCP) using an encrypted format to ensure security.
RDP uses the network port 3389 to transfer data related to remote desktop access. The data is packaged by the transport driver, directed to the Remote Desktop Protocol (RDP) and transmitted to the host computer. The host computer encrypts the data and sends it back to the client.
It is important to note that a stable and fast internet connection is necessary for smooth RDP performance. Additionally, RDP can support additional transport drivers for different network protocols based on user requirements.
