Work on everybody to the GCB be courts aren't.
There's a lot of things that we need to understand about TZP IP since it's a suite of protocols.
So through the course in its different sections we well first of all yes we'll look at just a brief
history which is interesting.
We're going to get to ing death or anything like that but it's something you should know where it came
from.
Was it meant to be for the other.
We're talking about way back in the 50s and 60s and 70s and then IP comes off.
OK.
Remember that TZP is all always connection oriented.
An IP connection unless they both have their all purpose.
That's why they're called A sweet.
That's why they call these stack Easy-Bake stack because there are different things that they do.
Now one will be comparing the TZP model to the side and to a new or finer layer.
OK.
Before that is going to be model or DVD as they like to call it.
And there was the deal who started this whole thing.
There were four letters original.
OK.
And now is really for.
They just broke it up into a fight.
Think layers layer's same means nothing different.
They just want to be a little bit more granular.
If for today's standards OK we'll look at how the layers map to all the different models.
We're on the oil side being the first one then the original TCAP model and then the newest model will
be breaking down different layers.
That is the model and also we'll be discussing the ports because remember not only do you need a source
IP destination IP source Mac destination MAC you need a port number one time for numbers.
Obviously there's well-known four numbers that we use on a daily basis that we're not aware of like
telnet or S-sh or HDTV.
All the or SMG all the we need to know that they're obviously working in the application layer but we'll
take a look at those port numbers as we get there.
Most importantly will be the addressing.
Is the IP portion model.
Yes.
We're going to go ahead whether or not you can get away from it.
Okay.
It's IP.
Okay.
You can't get away from IP when I say IP I mean IP addressing now or there's some terminology that you
need to understand.
Okay.
There's an earthquake plane the flat versus a high art.
Tickle everybody for word.
So you know what the differences are what the advantage is is our net worth in class ranges and private
IP address.
Basically I'm using a brief but a good solid foundation of IP because if you do not know IP addressing
whether what's a gateway do we need a gateway more.
So what if it doesn't have the same something in math just put whatever you want in there.
I don't know put all zeros put 169 through the fourth.
You need to know.
You know we watch IPs are going to be a broadcast that we are not going to be ridable on the Internet
IPs that are reserved.
OK you need to know about that.
Is this a multicast and who uses multicast.
Is is a broadcast.
Why would you use a broadcast where routers by default don't accept that.
So there's a lot of things that we're going to cover.
There's a lot to be huge of course but it will give you a very solid foundation to help you move forward
in your networking career.
You.
