Remote desktop protocol RDP is a secure network communications protocol developed by Microsoft. It enables network administrators to remotely diagnose problems that individual users encounter and gives users remote access to their physical work desktop computers.
RDP can be used by employees working from home or traveling who need access to their work computers. RDP is also often used by support technicians who need to diagnose and repair a user’s system remotely and by admins providing system maintenance.
RDP clients are available for most versions of Windows as well as for macOS, Linux, Unix, Google Android and Apple iOS. An open source version is also available. RDP is an extension of the International Telecommunications Union-Telecommunication (ITU-T) T.128 application sharing protocol.
RDP is a secure, interoperable protocol that creates secure connections between clients, servers and virtual machines. RDP works across different Windows OSes and devices and provides strong physical security through remote data storage.
