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!

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!

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?

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?

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?

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?
