What protocol provides a graphical interface to connect to another computer over a network connection?

The Remote Desktop Protocol (RDP) is widely used for connecting to another computer over a network and providing a graphical interface for users to interact with that remote machine. RDP is developed by Microsoft and allows users to take control of desktops and applications remotely, which is particularly useful in various scenarios such as IT support, remote work, or accessing a work environment from a different location.

RDP leverages a client-server architecture, where the client software on the user’s workstation connects to the RDP server running on the remote machine. Once connected, users can perform tasks as if they were sitting right in front of the remote computer, making it a powerful tool for managing servers and workstations.

In contrast, while Virtual Network Computing (VNC) also provides remote access, RDP is more commonly associated with Windows environments and offers a more seamless integration into Microsoft operating systems, particularly with features like support for sound, printer redirection, and more. Traffic Mirroring does not pertain to user interface access but rather focuses on monitoring network traffic, and the Domain Name System (DNS) is a protocol for resolving domain names to IP addresses, which does not offer a graphical interface or remote access capabilities.
