what is rdp server

Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft Corporation, which provides a user with a graphical interface to connect to another computer over a network connection. RDP allows users to control their remote Windows machine as if they were working on it locally. It is a secure, interoperable protocol that creates secure connections between clients, servers, and virtual machines. RDP works across different Windows operating systems and devices, and it provides strong physical security through remote data storage. RDP servers are built into the server and professional editions of Windows operating systems, but not home editions. Clients exist for most versions of Microsoft Windows, Linux, Unix, macOS, iOS, Android, and other operating systems. RDP servers listen on TCP port 3389 and UDP port 3389 by default. The protocol is an extension of the ITU-T T.128 application sharing protocol. RDP is widely used for remote troubleshooting, remote desktop access, and remote administration.
