Wish my CCNA teacher was this easy to understand. And for free !!

[@uav2246]

Been watching Mike Meyers on Udemy. He explains it differently with blocks, but its pretty close to the same. It's enough to make this a little confusing, but I'm sure that's because he is covering NET+ in those videos.

Took ccna classes a few years back and everything he's touched on thus far is on point. Having someone who loves what they do break it down in layman's terms is much more effective in teaching than being told to read and learn from some dry textbook. Excited to see more of these in the future! Thanks Chuck!

You are the best teacher I've found on KZbin by far. You actually explain everything in a clear and concise manner as you go along, instead of just throwing around IT jargon and assuming we already know what you mean, or explaining it in a very convoluted way. I thought I wasn't smart enough to learn this stuff, but with your videos I can understand all of this with ease. Thanks for doing what you do, Chuck.

[@IanSilk]

I struggled with this for the past few months, but now I get it. I must have watched this a few times before, but it never sunk in initially until recently. When it clicks, it clicks. Thanks for the content, it's really helping me in my career, and in my development in general.

[@efanheadford6735]

I'm a second year studying Cyber Security and Computer Forensics, and I'm making a video on TCP/IP and OSI for the first years and to go onto the uni's KZbin channel, let me just say that this video, as well as your other on TCP/IP and OSI have been absolutely invaluable to the process! I've not found anywhere else that's described and explained the process as well as you have, in a manner both technical enough to be useful, but conveyed in a way that is easy to understand. Great work!

As a software engineer of 4 years, and a university student of 4 years before that.. I've never seen someone explain the OSI & TCP/IP process better than this. You really broke it down amazingly. I spent years looking back at videos of networking trying to figure this stuff out. I eventually grasped it but it took way longer than it should've. I feel like if your video was around when I started, I could've grasped it from this video alone. Amazing stuff.

[@semtex6412]

3rd choice 1st question - is WAY MORE fuzzy. because that sounds like TCP to me. if i have to be nitpicky, i'd say it's particularly in the vein of source & destination PORT NUMBERS. see, the application (i.e., the program) that sends a request to the server creates a RANDOM SOURCE PORT number so that when the server responds to that specific request, that's going to be the server response's DESTINATION port this time. when the client computer receives it, its operating system knows which application started this communication to begin with --> by looking at the destination port, cross references the requesting application's source port, match is made, data is sent. ergo - 3RD CHOICE: "DIRECTING DATA to the correct program" HARD CASE IN POINT: kzbin.info/www/bejne/ZoPFaXShiap0idk

[@Gamelover22478]

I seriously cannot thank this man enough for going so in-depth with how this all works. Thank you 🙏 although I did start to get confused about the encapsulation and de encapsulation. What’s the purpose of doing that over and over for each layer ?

[@jay-9197]

Anyone is welcome to correct me if I'm wrong, I'm new to this as well. As in the example in the video, imagine it's a letter which being put into more and more envelops(encapsulating) as it goes further down the layers. Each layer has it's special envelop and on each envelop is written more information that the other layers don't know about. Imagine each of these envelops is written in completely different languages. Then the router receives this big package, and starts unpacking it until it finds an envelop with information it can understand(Layer 3, IP addresses..). Once the router knows where to send this bundle of envelops, it packs it all together again nicely and sends it to the correct destination. From there starts the processes of fully unpacking(de-encapsulating) by each layer in the destination. Basically doing the opposite of what happened while packing the letter to send it. Remember that each layer is simply there to represent certain devices, programs, type of information, etc. Like routers, switches, cables, different applications, IP addresses, MAC addresses etc. Each of these can "understand" only certain information, which is why it can only read and add information it understands. Hope it makes sense!

[@Gamelover22478]

@@jay-9197 that does make sense! Thanks for clearing it up. It’s so cool to hear how it works from under the hood. I’ve taken Cisco classes and I remember the processes of having to implementation encapsulation using the 802.1Q for the addresses but I only remember doing it once and I don’t remember actually de encapsulating it. So knowing how it works from each layer is amazing.

it's just example, on every port router has different mac addresses. for example , receiving port mac address was ending on X, and sending port mac was ending on Y.

[@msfkmsfk]

I like your channel a lot and I will continue to watch your videos because your teaching style is perfect for me because you break everything down and explain the basic flow of everything without using jargon and then once you've explained and defined the process you then name the process so it makes it easy to understand because you already explained it previously. Not that's probably an overcomplicated way of describing your teaching style but however you do it it is extremely effective and engaging not to mention all the diagrams and labs that you show also go along extremely well with everything you explain. Your videos are a great combination of visual and audio learning combined and I can't appreciate you enough for it.
