What Does Remote Desktop Connection (RDC) Mean?
Remote Desktop Connection (RDC) is a Microsoft technology that allows a local computer to connect to and control a remote PC over a network or the Internet. It is done through a Remote Desktop Service (RDS) or a terminal service that uses the company's proprietary Remote Desktop Protocol (RDP).
Remote Desktop Connection is also known simply as Remote Desktop.
Techopedia Explains Remote Desktop Connection (RDC)
Typically, RDC requires the remote computer to enable the RDS and to be powered on. The connection is established when a local computer requests connection to a remote computer using an RDC-enabled software. On authentication, the local computer has full or restricted access to the remote computer. Besides desktop computers, servers and laptops, RDC also supports connecting to virtual machines.
This technology was introduced in Windows XP.
