What is a Protocol ?
In Networking on 6:19 amIn a beautiful summer you have a picnic at a nice garden with some friends.
Immediatelly you’re meeting a stranger from another country which of course having a different language with you.
He asking you to get know each other and introduce him self to you.. Of course you don’t understand what his purpose, why ? of course because you are using different language with him.
You just taking it easy and introduce your self too. After all, you start to tell him about your beautiful country.. once again.. with your own language which unknown by your new friend.
You told him many things.. and immediatelly he bust you and take you to the police because he thought that you’re a terorist according to your conversations.. once again.. why ? sure.. because he dont understand your language.
Well, now lets finish the story and start the lessons… 
how important a Protocol are ? of course the answer are: very important.
the protocol allow some device (in this case computers) to communicate each other.
We can say that protocol is a language for human being.. by the protocol devices can share information, share the source or even some connections to internet.
there are many protocol invented. As long as my experience each vendor has assign their own protocol to connects their devices.
as example Novell with NETBios, Aple MacIntosh with ApleTalk also Unix with IPX.
OK, enough for this time.. see you at next tutorials..
bye!
