RDP

The RDP was developed for Microsoft and is used primarily to connect to a remote machine, server, desktop, or virtual machine using TCP IP. The RDP is now more commonly known as the Remote Desktop Connection. You probably use it daily to connect remotely to your server infrastructure in order to manage servers remotely.

When you connect to the remote desktop or machine, you are essentially connecting to a terminal service component, which then relays the screen content back to the client, along with keystrokes and mouse movements.
