Understanding Segments, Packets, and Frames - Data Encapsulation Series

In this video we go into more detail about the data encapsulation process and discuss in a little more detail for our layer 4 segments, layer 3 packets, and layer 2 frames.

Dude, what a great explanation of the encapsulation process. I was reading Odom Wendell's Cisco CCNA book. He doesn't quite explain it in a way that worked for me. This video broke down this process that made sense. Thank You!

wireshark never made this much sense, thanks man. The way you break down the concepts, excellent !

The best video i've found on YouTube about TCP/IP model. I saw many in german and polish, but just yours is coplete! TNANK YOU SO MUCH!

[mrrairai]

These trainings are amazing. I understand all of this so much better now.

Thank You so much, your channel and your explanation is really amazing!
Please keep your channel updated!

[redhippieful]

I am finally understanding the difference! Thanks!

[MahipalYadavmahii]

excellent video, clears many of the obvious doubts that one can have while studying for ccna certification

The pacing is intense! Loved it though. It gave me a fuller understanding on the segment, packet, frames and bits part of the OSI model. Thank you!

Great quality video, hope to get some notifications from any new work in the future

[zenapplejones]

Had to slow it down to understand- I got it NOW !!!! Thanks !!!

This is the best explanation I've got on Networking, thank you so much sir.

The best video on youtue explaining this, trust me have done lots of searching..thankyou, keep doing more videos, pls cover SAN also..

[allybiggs]

Excellent clear and concise explanations I now understand the encapsulation process thank you :)

[lukasbeacon]

Than you so much!! Awesome instructor. This is amazing content

I understand why the packets are built but not the how they are built. It would be very useful to also know, *where* does the transport layer get the port numbers from? Where does the Network layer get the IP addresses and how does the data layer get the MAC address of a machine that is on the other side or the world?

[TheMyth.]

Hi, this is a good tutorial. I am just a bit confused about a few things. I thought MAC addresses were only there to resolve local IP addresses? So if a packet is moving from one router to another and they are in different networks, how will it get the Mac address?

[donhjoe]

I have a question, there are 2 computers connected directly and configured to be a point to point network I mean PC A and PC B. And I want to send a data (word, name, characters) from one computer to another (from A to B), How the computer B knows that the package have been send completely from computer A, in what layer this happen?

[waterwalker]

Man, you talk fast but great video! Very well explained.

[slyuk]

Very useful video...but at warp speed! :-)

[spacefentionz]

I understand everything except what unpacks the segment layer and how. The router needs to remove the frame layer in order to see the ip address, and then repackage the data block in another frame and then send it off, but what I don't understand is where the segment is looked at. The destination port is 80, and I thought that that was handled at the router level as well (firewalls are usually on the router), but you didn't really talk about that part. What am I missing?
