I see your point here.  I have included my personal expierence in my resume.  
I was hoping by putting it there that it would be picked up on in a way that 
you have mentioned.  Maybe it will.
The more I read around I am seeing what you have said about big companies 
wanting certs.  I have found a much smaller company that needs help from time 
to time (Which fits in with my college sched).  This will enable me to get 
something more tangible on the resume.
Thanks for the reply.

Thanks Mike. I went and re-read text about the OSI reference model because
you mentioned Network layer and link layer in your previous response.
Then it became clearer. Packets originate in network layer. Frames in link
layer. As such packets are in frames. There could of course be one packet
in a frame or more.
