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

@PracticalNetworking 3 года назад

I hope so =). Thanks, Badrinathan!

@PracticalNetworking 3 года назад

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.

@kashish1424 Год назад

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.

@PracticalNetworking Год назад

@@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/

@rotrose7531 2 года назад

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.

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.

@PracticalNetworking 2 года назад

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_ .
