Transport Layer protocols, such as the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), specify a source and destination port number in their segment headers. A port number is a 16-bit unsigned integer, thus ranging from 0 to 65535. However, for TCP, port number 0 is reserved and cannot be used. For UDP, the source port is optional and a value of zero means no port. A process associates its input or output channels via Internet sockets, a type of file descriptor, with a transport protocol, a port number and an IP address.
