Similarly many of the official assignments refer to protocols that were never or are no longer in common use. This article lists port numbers and their associated protocols that have experienced significant uptake. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well-known ports. They are assigned by IANA for specific service upon application by a requesting entity. From Wikipedia, the free encyclopedia.

Both of these protocols are involved in the process of transmission of data. While UDP is used in situations where the volume of data is large and security of data is not of much significance, TCP is used in those situations where security of data is one of the main issues. While the transfer of data, the existence of ports is a matter of high significance. Each data packet comes with a port number associated with it. This enables the protocols to decide that what are the requirements of the data packets and to which port are they supposed to be directed. In fact, the existence of ports is crucial to make sure that data packets reach their desired destinations accurately.

TCP/IP Ports and Protocols

Below, we take a look at these protocols, provides a basic description of their function, and lists the port numbers that they are commonly associated with. FTP is one of the most commonly used file transfer protocols on the Internet and within private networks. An FTP server can easily be set up with little networking knowledge and provides the ability to easily relocate files from one system to another.

Udp Port Numbers. A protocol is a set of formalized rules that explains how data is communicated over a network. Port ranges from , covering all Well Known Ports, along with severity levels of low, medium, high, and critical, are displayed.

 Нет, конечно. Я просто подумал… - Толстяк быстро убрал бумажник.  - Я… я… - Совсем растерявшись, он сел на край постели и сжал руки. Кровать застонала под его весом.
