NetBIOS Name Service operates on which port number?

Explanation:
NetBIOS Name Service handles registering and resolving NetBIOS names so devices can find each other by name, and it operates over UDP port 137. The other ports have different NetBIOS functions or are unrelated: 138 is the NetBIOS Datagram Service for broadcast messages, 139 is the NetBIOS Session Service used for SMB-style connections, and 119 is a separate service (NNTP). So the port used by NetBIOS Name Service is 137.
