Wireshark · Wireshark-users: [Wireshark-users] Hex numbers and fields

[Lisi <lisi.reisz@xxxxxxxxx>]

I'm sorry, I obviously don't know enough about networks for it to be sensible 
for me to use Wireshark.  But I am where I am, and I want at least to try.

What is the connection between the fields and the hex numbers at the bottom of 
the screen?  I can see that there is one, but I couldn't even begin to use 
the hex numbers to enable me to describe the fields, which is what I am 
supposed to be doing.  I need to go the other way round!

And what are the letters, numbers, dots and symbols beside the hex numbers? 

I have Googled, I have searched the Wireshark site, I have searched the course 
text book.  I cannot find anything that describes this.
