How Does RDP Work? Here’s a Simple Breakdown

Connection Setup

RDP operates by establishing a remote network connection between a client computer and a host computer. 

The client uses RDP server software to initiate a connection request, which the host must accept. This connection can be made over the Internet or through a local network, depending on the RDP client software setup.

Display and Interaction

Once the connection is established via the remote desktop software, the desktop interface of the host computer is transmitted over the network to the client computer’s display. 

This allows the user at the client computer to see and interact with the host computer’s desktop environment as if it were local. The client can open files, use applications, and manage settings remotely.

Data Transmission

Interaction details such as mouse clicks, keyboard inputs, and other commands are sent from the client to the host, where they are executed. Responses from the host, including graphical updates, are then sent back to the client. 

This two-way communication happens quickly to ensure a smooth user experience as if the user were directly interacting with the host machine.
