How to interpret newsgroup headers

Below are some typical headers. I'm just wondering what each group of characters means. Some change during use, some change when the power is turned off. Others stay the same. Just curious.

If there is a newsgroups specific to headers, I would ask someone to please let me know.

Thanks in advance.

Typical examples... I added the spaces to separate the groups...

PS - It's easier to see the grouping using a fixed font.

Are you asking how to interpret Message IDs? Each newsreader has its
own, ideosyncratic method for generating them. They're generally a
combination of some characters that are generated from information
unique to the client machine, so they won't conflict with posts from
other clients, and some characters generated from the posting time, so
that messages from the same client will not have duplicate IDs.

In your case, I'd guess the RHD5iwII3 part is the machine-specific part,
while the stuff to the left of it comes from the time.

And the OP can read more about them e.g. here:
