A port is a 16-bit unsigned integer, and the total number of ports available in the TCP/IP model is 65,535 ports. Therefore, the range of port numbers is 0 to 65535. In the case of TCP, the zero-port number is reserved and cannot be used, whereas, in UDP, the zero port is not available.
Port 9000: for requests using TCP or UDP protocol. Port 9002: for requests using PDP protocol. Port 9099: for general requests through TIBCO Accelerator.
Port 30000 Details Stack-based buffer overflow in NT_Naming_Service.exe in SAP Business One 2005 A 6.80. 123 and 6.80. 320 allows remote attackers to execute arbitrary code via a long GIOP request to TCP port 30000.

Port 21 is commonly associated with FTP. FTP has been assigned to Port 21 by the Internet Assigned Numbers Authority (IANA). The IANA also oversees global IP address allocation. FTP is often thought of as a “not secure” file transfer protocol.Nov 29, 2018

By default, port 22 is open on all IBM StoredIQ hosts. The port is used for Secure Shell (SSH) communication and allows remote administration access to the VM. In general, traffic is encrypted using password authentication.
Transmission Control Protocol (TCP) – a connection-oriented communications protocol that facilitates the exchange of messages between computing devices in a network. It is the most common protocol in networks that use the Internet Protocol (IP); together they are sometimes referred to as TCP/IP.
Answer: The most common alternative is UDP ( user datagram protocol ). UDP is designed for applications where you don't need to put sequences of packets together. It fits into the system much like TCP.Oct 18, 2020
If you lose several packets in the middle of the message the recipient might not even receive the message and if they do they might be missing key information. This makes TCP more appropriate because it ensures that every packet is delivered. UDP is NOT a reliable ordered data stream channel.May 29, 2013
