00:00:00,330 --> 00:00:03,960
We use the term modeling quite a bit within the networking world.
2
00:00:04,110 --> 00:00:09,090
And, in order to understand why we use the word modeling, I'd like to take a minute and discuss, what is
3
00:00:09,090 --> 00:00:09,960
a model?
4
00:00:10,020 --> 00:00:14,450
So up here on the screen I've got three examples of models. On the far left
5
00:00:14,490 --> 00:00:17,520
I've got a weather forecasting model, in the middle
6
00:00:17,520 --> 00:00:22,950
I've got a model airplane, and on the far right have an incredibly attractive male model, that's my buddy
7
00:00:22,950 --> 00:00:24,500
Ford Pearson.
8
00:00:24,580 --> 00:00:27,170
Anyway, all three of these are models,
9
00:00:27,240 --> 00:00:29,040
but obviously they're quite different.
10
00:00:29,040 --> 00:00:35,410
So, what is the theme that ties these three otherwise very different things into the term model?
11
00:00:35,490 --> 00:00:42,570
Well, first of all, it's representation. Whether a model of weather, of an airplane, or of a person,
12
00:00:42,600 --> 00:00:49,270
these represent, in some aspects, a fairly idealized idea of what the real McCoy is.
13
00:00:49,320 --> 00:00:53,370
For example, the model airplane in the middle doesn't have oil stains all over it and things like that.
14
00:00:53,370 --> 00:00:55,530
So it's a bit idealized.
15
00:00:55,530 --> 00:00:59,820
The other thing, is that they're simplified. On the far left,
16
00:00:59,850 --> 00:01:06,750
the weather model doesn't put into every molecule for its consideration, and the far right hand side
17
00:01:06,870 --> 00:01:10,680
we don't worry about the fact that Ford actually has a bad cold that day.
18
00:01:10,680 --> 00:01:16,380
We're really worried about the simplified processes that allow us to represent the form and function
19
00:01:16,530 --> 00:01:17,840
of the real McCoy.
20
00:01:18,090 --> 00:01:20,820
And that's what networking models are all about.
21
00:01:20,820 --> 00:01:26,500
There are two networking models on the Network+. There is the OSI seven-layer model,
22
00:01:26,610 --> 00:01:28,950
and then there's the TCP/IP model.
23
00:01:28,950 --> 00:01:33,840
We need to go over both of these in great detail, and we're going to be using the next several episodes
24
00:01:34,110 --> 00:01:40,320
so that you can understand both the OSI and the TCP/IP model, not only so you can pass the Network+,
25
00:01:40,560 --> 00:01:42,990
but so you can talk the Network talk.
26
00:01:42,990 --> 00:01:46,600
So, let's get started into the world of modeling!
