NBT exposes information and interfaces that are often appropriate for a LAN under an organization's administrative control, but which are not appropriate for a less trusted network such as the Internet. For example, the NetBIOS Name Service (NBNS), running over UDP or TCP port 137, allows any computer to register its hostname with other computers.
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
A port is a software structure that is identified by the port number, a 16-bit integer value, allowing for port numbers between 0 and 65535. Port 0 is reserved but is a permissible source port value if the sending process does not expect messages in response. The Internet Assigned Numbers Authority (IANA) has divided port numbers into three ...
For TCP, port number 0 is reserved and cannot be used, while for UDP, the source port is optional and a value of zero means no port. A process associates its input or output channels via an internet socket , which is a type of file descriptor , associated with a transport protocol , a network address such as an IP address , and a port number.

The API was created in 1983 by Sytek Inc. for software communication over IBM PC Network LAN technology. [1] On IBM PC Network, as an API alone, NetBIOS relied on proprietary Sytek networking protocols for communication over the wire. [2] In 1985, IBM went forward with the Token Ring network scheme and produced an emulator of Sytek's NetBIOS ...
Wireless Application Protocol (WAP) is an obsolete technical standard for accessing information over a mobile cellular network. Introduced in 1999, [ 1 ] WAP allowed users with compatible mobile devices to browse content such as news, weather and sports scores provided by mobile network operators , specially designed for the limited ...
UDP-based Data Transfer Protocol (UDT), is a high-performance data transfer protocol designed for transferring large volumetric datasets over high-speed wide area networks. Such settings are typically disadvantageous for the more common TCP protocol.
