How to configure receiving connections through 8080 (port): instructions, diagram and reviews

A port on computer networks is a natural number that is written in the OSI protocol header. It is intended to identify the process of the recipient of the package in one host.

As a rule, in a user space on a host with an installed OS, several processes occur simultaneously, and a specific program runs in each of them. If these programs affect the computer network, the “shell” from time to time receives through it an IP packet, which is intended for one of the programs.

How it works?

If the program uses data exchange over the network, this process can occur as follows:

• The OS is prompted for a specific port number. In this case, the system can both provide it to the program and prohibit the transfer (this happens in cases where this port number is already used by another application).
