Very, very elementary question - how do I make sense of the trace?

[Lisi <lisi.reisz () gmail com>]

I cannot find anywhere a basic and simple enough explanation of the meaning of 
the output from Wireshark for me to be able to understand it (the output).  

Can anyone recommend something that I could read, that might slightly reduce 
my ignorance?  My ignorance is so total that I do not even know what 
questions to ask, so that Google is sadly not my friend. :-(.

Thanks,
Lisi
