The Remote Desktop Protocol (RDP) is the network protocol used by Terminal Service client devices for client-to-server session communication. The RDP protocol actually transmits keystrokes and mouse movements from the client to the server, and screen images from the server to the client.
RDP and VPS are the same, the only difference is RDP is shared with many users and VPS is a private server, it's non shared with full root admin access. In VPS you can choose O/S accordingly like Windows 10/ Windows 2012/ Windows 2016.
