Oh absolutely. Well, considering you're working on a
   computer-like device now and utilizing the very same systems
   you're learning about... maybe a packet sniffer that shows you
   the packets coming in and out could help?

   Or maybe look at your router's settings and try to see it from
   that angle.

   Another might be to read the headers in an email message, or
   look at the TCP/IP protocol by using Telnet into a system and
   going onto a webpage.

   You can WATCH the communications take place - all in English -
   as it happens.
