TCP/IP in simple terms
S.GURUMANICKAM
Prologue: MISSING THE WOOD FOR THE TREES: Very few view the TCP/IP
fully. Everyone knows what an IP is and nearly have perceive about MAC addresses.
Ask them what is TCP, what is its role? A snowy stare would be the reply. Add the
MAC; its very a jungle out there. It just throws anyone away. It would be in truth nice
to know, where they fit, how they interact with each other. Isnt it.
I had valued to understand it in simpler terms and burnt many a midnight oil towards
that goal. After an eon and after having learned to some extent, I would like to share
with anyone who doesnt want to go through that ordeal.
It is truly missing the wood for the trees when you get befogged in anyone of the seven

With a real world example, I will try to explain what is actually happening in an
allegorical way relating to the TCP/IP.
