Everything Hosts do to speak on the Internet - Part 1 - Networking Fundamentals - Lesson 3
ฝัง
- เผยแพร่เมื่อ 9 มิ.ย. 2024
- Module 1 of the Networking Fundamentals course will illustrate the core of networking: How data moves through the Internet. In this lesson, we'll explore Internet commuication from the host's perspective. We'll illustrate EVERYTHING a host does when speaking with other hosts on the Internet.
We'll do this with two illustrations:
First, we'll look at everything that occurs for two hosts which are directly connected to each other do to communicate.
Second, we'll look at everything that occurs for two hosts to speak which are on opposite sides of a Router.
Remember, Hosts don't know what they are connected to. Our first illustration also applies when hosts are connected through Switches and Hubs. And our second illustration also applies when hosts are connected through multiple Routers.
These two illustrations will cover 100% of the scenarios that hosts use today to send data through the Internet.

practical networking is creating a masterpiece
I hope so =). Thanks, Badrinathan!
Hey everyone, I hope you enjoyed that video! I try to put most of my effort into creating effective, practical teaching videos for you. Which means I can't put a lot of effort into marketing. Which is why I need your help! If you enjoyed this video, please share a link to this video to a few of your friends or coworkers, or post this to LinkedIn, Reddit, Discord, Facebook, or any other social media you might use. You'd be doing me a big favor, and it will encourage me to continue publishing videos. Thank you.
Would it be possible to provide the slides? Or you could have the same videos transcribed on your website. It would help a ton for a quick revision.
@@kashish1424 I'm afraid I can't provide the slides ... some of the editing was done in post processing, so it isn't fully contained in just the power point =/.
If you prefer written content, I did this same series as a set of blog articles, that might help: www.practicalnetworking.net/series/packet-traveling/packet-traveling/
Excellent! Thanks.
You are the ultimate definition of a genius. I am so blessed about how you detail the processes without leaving any grey area. Thank you. Please keep this generosity going. You are a blessing to the world!
Thank you for the kind words, Azza =). I'm happy you are getting so much out of these videos and this series.
Thank you you are a very resourceful channel!! You think this would help me with the Network+ certificate? And if you could can you make a series for network+ exam following the objectives and I will watch your videos and follow your lessons pleaseeeee???

I did a Apprenticeship as Hotelspecialist and wanted to change my job, so I watched your TH-cam series and convinced in the interview, after a 2 years as a IT-firstlevel supporter.... Since 2 Months i am It-systemadministrator. I am on the same level of knowledge with my colleague because I have pulled through. Although some studied computer science.
Thanks for everything :)
I needed to learn about computer network fundamentals for cybersecurity and this is exactly what I needed at this point. This is literally perfect for me. Thank you so much for this whole playlist!
I have read many books and watched many videos about networking and OSI Model but so far this is the best. you made it better to understand without memorizing the concept. You have a simple and practical way to make a big subject easy to digest. Thank you
Thank you for the kind words, Aziz. I'm glad you've enjoyed this content =)
Currently studying for the CompTIA Network + and your videos have made me feel like I can take the test tomorrow and pass it. I’ve particularly struggled with some concepts, but your way of explaining things is beyond remarkable. Thank you so much for putting out great videos.
Ed is the BEST Networking educator on TH-cam - so clear and precise explanation of any topics. Thanks Ed, can you please also teach us Value Investing too hahha...😂
Thank you again, RiseOfTibet =). I appreciate your support! ;)
Many causes explain these concept on a part by part basis, so it is difficult to see the whole picture, but this couse bind these all together and follow the sequence one by one, now it is difficult to forget the whole picture. Genius.
So glad it's all fitting together and making sense for you =). Now you can help teach others the same !
Wow😲... I can not believe the way you teaching this subject.. so simple to understand... It amazing
Thank you, Ajewole.
I am usually not a person who likes online learning, but you have taught in such a simple way, even without a background of Networking , I can understand every step you explain. Thank you 😊🙏🏽
Love your sense of humour.
Keep up the great work and this is the most clear training course I've ever had,
🙂
"Screen Real Estate"😂😂 Will definitely incorporate in my vocab
The way you put those concepts in our minds is incredibly amazing. Thank you very much.
I am watching this again, like new wine, its evergreen. Thank you.
most of the materials teaching CCNA just teaches what this does, what this definition and what it function but doesn't really provide linking or context on how it relate with one another, you're video helps a lot on helping linking what this have to relate to this, Thanks you don't know how much simpler to understand is watching your video
So glad this video helped link ideas to each other =) That is very much a goal of what I am trying to do with this series.
true bro. It will just be like ok these are all the layers. Bye. Instead of explaining how they work together and what they all do. This man is a literal G.O.A.T
This video series is a brilliantly concise illustration of networking basics. Essential for everyone to understand nowadays since most people use the internet in their life.
No one can explain networking as simply as you , you are a genius
Actually, I was disappointed to learn networking until I saw your videos that are so beneficial and clearly explained..Thank you so much for this.
The best channel.
Goodness, this is so well-made
This is a great channel. Thank you so much for creating it and making it available. Computer networks finally make sense to me.
You're very welcome! Glad to hear Computer Networking makes sense now =)
This series is great! Simple and easy to understand!
I don't think anyone could explain fundamentals so great like this to a common man like me .. continuing with your lessons .. 🙏🙏🙏🙏
Thank you for the kind words, Antony =). Glad you're enjoying this series!
I can't thank you enough for your easy-to-follow and easy-to-understand video's. I have watched several of them so far and plan to watch all of them over time.

Please keep up the magnificent work, you are truly gifted, and I can't thank you enough!!! 👍😀
You're welcome, Mike. Thank you for the kind words. I'm glad you got so much out of this video, and I hope you get just as much out of the full series! =)

*Full Course Status: Wait and See.*
Hopefully you've come to realize that I put _a lot_ of effort into the content I create. I'm not a course creator that will simply turn on the screen recording and ramble, then call that teaching. I meticulously plan _every_ module and lesson to _maximize the learning and value_ for the student.
To that end, it takes me a while to put together courses. If I'm going to dedicate the time, resources, and energy to putting this full course together, I need to know that there is enough interest in the full course. I'm rating that by how wide a reach this series achieves.
*If you are interested in seeing the full course developed, then the best way to bring that to fruition is to spread the word about this content* . By itself it already conveys _a lot_ of value. So sharing even just the 7 lessons (13 videos) in this series will surely help whoever you share it with.
Plus ... many online communities would greatly benefit from these videos. Think of all the Internet points you could acquire if you shared this series (karma, likes, follows, etc.) 😉

Excellent video explanation. So clear and so easy to understand. Looking forward to the rest of the video course. My question is not later to this lesson or course but I am interested to know if you'll be doing similar courses on cyber security. Many thanks and keep up the excellent work.

I just finished a full course discussing SSL and TLS in great detail. Maybe that would be of interest to you?

Great learning experience thank you so much.....
You're welcome!
Great job
way to go. awesome explanation
This lesson is really crucial to understand ARP for the first time.
Thank you, Gman =). I've enjoyed seeing your comments on the videos that follow =)
great video!
This is the best video series on networking i have ever watched in my life. Thank you so much. I am curious to know if you are releasing the full course at some point of time in the future. I would like to purchase that course and hone my networking skills. In addition, i would also like to see some hands on exercises using something like Cisco Packet tracer.
Thanks for the kind words, Kiran =). You're very welcome.
I have a few other projects I'm working on, but creating this full course is certainly on my mind. I have some Packet Tracer walk throughs here: www.practicalnetworking.net/stand-alone/packet-tracer-labs/
thank you straight to the point
You're welcome!

Super video.
Thank you!
Header heaven - too good😍
hanks lot Sir.. You helping us..
You're very welcome.
I AM HOOKED!
Mind you that I am a layperson.
I came across your channel by sheer chance and I won’t let go.
With your smashing narration and presentation, I have already understood basic concepts I had never, EVER, taken the trouble to look into.
Bad for me and shame on me… but it’s never too late.
Question as a true novice (still, extremely curious and it just popped naturally as a question): does this (seemingly ?) innocent, initial ARP broadcast present any sort of potential security liability for the host who makes it?
Thanks and cheers.
Hi again, happy to hear you're loving this series =). Please keep going w/ the rest of the videos!
Great question! And good instincts... the issue is ARP is "everyone" on the network gets it, and "any" answer is accepted. Which leaves the door open for a malicious host providing the wrong ARP mapping. This can lead to "ARP Man In The Middle (MITM)" attacks.
If you've enjoyed this series as much as you have, could you do me a favor? Do you mind sharing this video on Linked In, Reddit, Twitter, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ .
@@PracticalNetworking thanks for the response, Ed! Appreciated! Sure thing. I will share the link of this series. Cheers!
