A port is a channel on a machine, that can be used for communication. There are 65536 different ports (0-65535). Some are standarized, that means they are bound to a given defined task, like the mail ports, web ports, and others…
All other ports can be used as one sees need.
Knowledge of ports is important for the configuration of the firewall, to open required ports and close the rest. Communication over a port requires the port to be open.
Therefore it is useful to know the standarized ports and ports required by some programs.
