What is the default port for RDP (Remote Desktop Protocol)?

The default port for Remote Desktop Protocol (RDP) is 3389. RDP is a proprietary protocol developed by Microsoft that allows users to connect to another computer over a network with a graphical user interface. The use of this specific port is standardized, making it essential for configurations involving remote desktop services, as it enables client machines to establish a connection with the server hosting the remote desktop session.

When setting up a remote desktop service, ensuring that traffic through port 3389 is allowed in firewalls and network configurations is critical for successfully accessing the remote machine. Other ports mentioned, such as 8080, 53, and 80, are reserved for different protocols and services, and do not apply to RDP functionality. Therefore, understanding that 3389 is specifically assigned for RDP is crucial for anyone working with remote connections in networked environments.
