thanks for your reply.
It helps, though I am trying do write a less abstract statement. 

Would you say that the following statement conveys a correct understanding
of the matter of fact:  

---- the Internet protocol contains numerous parameters, for example to
identify the character set of a text, or a operating system. (A character
set is a set of conventions to code a traditional alphabet, e.g. latin,
cyrillic, japanese). The values of these parameters need to be assigned
uniquely. ICANN/PSO is to make those unique assignments and to maintain a
registry of the currently assigned values.

(here I am cutting & pasting statements from IANA's web site)  


ps do you have a two lines definition of what a port is?
