Everything Hosts do to speak on the Internet - Part 1 - Networking Fundamentals - Lesson 3

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.

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.

[@PracticalNetworking]

@@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 =/.

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.
