What is the Remote Desktop Protocol (RDP)?
The Remote Desktop Protocol (RDP) is a protocol, or technical standard, for using a desktop computer remotely. Remote desktop software can use several different protocols, including RDP, Independent Computing Architecture (ICA), and virtual network computing (VNC), but RDP is the most commonly used protocol. RDP was initially released by Microsoft and is available for most Windows operating systems, but it can be used with Mac operating systems too.
