Welcome to Saberi Empty, A 98 3 66
network and Fundamentals certification prep course. Now, if you recall in the previous Marge or previous presentation, I personally walk to do several questions pertaining to Model one now in Marjah. When we discuss understanding NOK area networks, we learned their different types of networks, ranging from local area network
too wide every network to man as well. In addition, there's some additional networks as well.
Eager is important. You learned that understanding. Look, Aaron Network. It's a search a foundation for this particular course of instruction.
Moving onto margin number two now in modern to we're gonna take it a step further. We're gonna move into the topic of the finding networks with the oil side model on your side model stands for the open system interconnection model. Now it's a reference to for understanding data communication between
any to network
systems. We'd also discuss understanding switches as well in this particular module. Two.
So let's take a look at the objectives. First course of instruction.
First of all, we begin by discussing the ice. Our model
the next time we discuss revived you with an overview off the West our course, our model is well.
We discussed the topic of analysis and comparison.
Then we're moving to model design. That's all going to discuss it in this particular Marjorie or particular video presentation
in the upcoming presentation will move on to the topic off
real verdict communication as well as effective horizontal communication. We discussed the seven layers off the ice I'm on in terms of what happened in each of those specific layers, and we'll finish out the round up this course by looking at the TCP I P model as well.
So let's take a look at an assessment course, and that's perhaps the best place began in this particular course of instruction. In the first question that I have for you is this.
How many layers of Stax or layers or stack comprises again the OS our model? Is that a four?
Is it B seven,
or is it c nine or deep?
If you said, like, maybe you're absolutely correct, their seven layers in the O. R S I. R model.
Now that is important for your organization.
Therefore, it's necessary again for us to be able to send it down to another location easily with a minimum amount of time.
And so the West I'm on is one model that we can actually again that we can use. In terms of demonstrating this,
the data could be sent to the destination using network A network again, as you recall from previous presentation, is a collective interconnected devices such as your computer. Prentiss. But sharing the various resource is now has this information moves again from transmit
up to what we call received out. It goes to a prices ago encapsulation as a move down the different layers,
and as it moves up the stack on the other end terms of receiving data, it goes to a price of de caps elation, not an encapsulation. The data moves from the upper layers to the lower layers, and each layer includes a bummer of information known as a header, along with the action data while en de caps elation.
What happened? The data moves from the lower layers
to the upper layers, and each of their unpacks the corresponding ETA to obtain the actual data.
So what is open system in the connection model?
It's a reference mark is essential component of computer network design since its inception back in 1984
the I S 00 S. Our motto was developed because it appeared that IBM was goingto Patton design of its estimated network so that no one else could use IBM design model for networking.
And so again, the S I r model. Basically, you cannot by the wayside tomorrow
again. One of the main purposes or three purposes to analyze allows you to be to compare. And lastly, you able to troubleshoot particularly, let's say for that, for you having a network issue again,
obviously one in the first place will begin at the very lower level. Whether they're going essay is a little three issue or later. One issue, obviously the best in the new look. A lot of time, your issue. Maybe a little one issue like, for example, at the physical, maybe a cable.
That may be the issue, and not necessarily what we call a layer three issues.
So again, no es armada is an abstract modern mean that actual network implementation need not adhere to it. Strictly horse eyes. Also a steady effort, a product of the international standard organization.
Now let's take a look at it over your door, side or sigh. Morrow, a network and Mara. Again, this model officer generic means to separate computer network and function, and to multiple layers.
Each of the layers were lies on the layers below to provide supporting capabilities and perform support to the layers above
such a model of lire functionality, Also called a protocol. Stack our protocol sweet.
So what's something Benefits of us? Our model.
First of all, he has used understanding. Big pitcher of networking. It has used understand how hardware and software elements function together.
It makes Trump Street easier by separate networks into what we call manageable pieces. It also defies a term that network and professionals can use to compare the basic functional relationship on different networks. It helps the user's understanding new technology as they are developed.
It also aids in interpreting Bender explanation
Ah, product functionality as well.
Now let's take a look at your side money for med analysis and comparison, as I mentioned earlier that it's not the only model right there again. As we could see, he was seemed that where we see teacher happy model, we said it was our motto. The IBM ES and a martyr as well as Appleton and open sister in a connection. Morrow
is a conceptual model knit characterize in standardized the communication function
off your telecommunications computer system without regard to its underlying internal structure and technology.
Now four source. I'm modest concerned memory. There were looking a different layers in this particular sly. We're comparing the TCP martyr as opposed to the OS. I model what we see here that each layer, maybe a protocol
and some protocols other words to my rules. And that's what protocol is, in fact. And there's don't match up perfectly with again when you look at the TCP I model, not one thing interesting enough that each layer interacts with them immediately above and well, as below. Now, one thing we're going through the process of comparing
again us. Our model wouldn't teach that be model once they want to mention here.
The rest I'm ANA is a generic protocol independent standard,
acting as communication gateway between the network and the end uses wound on the hand. Were you thinking about the TCP F P model is based on standard protocols or rules around which the Internet has developed. It is a communication protocol, which allows connection off hosts over a network.
just a reminder or some model again is a stands for open system in the connection model. It's been developed by Iess or International Again. Organization of standardization
is a seven Liam Otto.
All these seven lives work collaboratively to transmit data from one person to another across the globe.
Let's take a look at post assessment question here.
What it's not an invention of the West are marked.
Is it a. It helps us understand the big picture of networking.
Is it be make troubleshooting easier by separate networks into manageable pieces? Or is it seeing ace and interpreting been explanation of product functionality? Or is it D? It makes troubleshooting difficult, and it's hard to understand
now if you said like the D, you're absolutely correct.
Now, during this particular course of structure, we discussed the US our model. We learned that the S Armada is braced based upon seven layers. Oftentimes for two at seven stacks, we learned some of the benefits of the Orson. Tomorrow we looked at analysis and comparison again of the various models,
realizing that the West Armada is not the only more out there.
We also discussed modern is that is well,
now, this brings us to the conclusion of this particular course of instruction.
Nine upcoming presentations would be just taking a look and discussing Riel Berta communication.
And we have finished around at that particular president by discussing effective horse owner communication as well. So again, we're gonna be compared as west compare contraction. What? Israel verdict. Communication as opposed to effective hordes on a communication.
I want to thank you very much for your attention detail
during the course of this particular presentation.
And I look forward to seeing your future training presentations.
