HTTP vs HTML: Unveiling Network Protocols using Telnet

At the surface, this video is about HTTP, HTML, and Telnet. But beneath that this video is actually a demonstration of how every Network Protocol works. A Connection is made via TCP or UDP, a request is sent, a response is received. We demonstration this with HTTP / HTML / Telnet, but this same sequence occurs with nearly all other protocols as well.

In this demonstration, we show you exactly what your web browser does: It initiates an HTTP request in order to download an HTML page, and then it renders it in a way that is more visually appealing.

So, what do you think... was that not the _greatest_ web page ever created? 😏

[kevinconnolly]

You are without a doubt the best networking resource on youtube, if not the internet. Many thanks

[azeezkola]

Thank you. It is nice seeing the face behind the informative series of NETWORK FUNDAMENTALS. Thank you once again.

Yes! Finally learnt how webpages do the magic. Btw I am not a network engineer. But it is valuable to know these things. It helps to connect the dots.
I love the way pace your words. You would be a good lecturer in top universities.
Thank you!

Man you're a true gem, you explain things super clearly and simply.. big thumbs and big thanks

Looking forward to this, the current videos have been great. I've gone from procrastinating to watching all your videos on networking over just 2 days!

[rigelmandarakuriom]

It was a timely explanation. Thank you

[infantajeesh]

Outstanding video ❤ . Expecting from you some more videos from TCP series as you said.

[KarthikR-mhtj]

Hello Sir, that was a very good video on the HTTP basics.
Would be really appreciated if you could provide a deep dive on the telnet protocol.
Thanks for the video. keep inspiring us with great content.

[MrMkarakaya]

I really like your videos. Thanks for your time and effort.

[BrunoMiguelLoureiro]

Hi Ed, thank you for the awesome video series 👍 The first mention of the upcoming course was 3 years ago, do you still plan on going through with it?

[Easy-Console]

Very well. So the HTTP request consists of basically two steps 1. Make socket connection 2.Send appropriate HTTP protocol string and receive response ?

[waverache]

Next video on : all types of authentication method ( ie oauth, cert based, MFA, etc ) . Can we have that ????

@ 3:22

Is it possible to use WSL (Windows Subsystem for Linux) to try out telnet connection like that?

[Tanibu]

Well, I am not a native English-speaker. Do you have caption on your website(multi-languages)?

[franciscopen]

now, could you explain what do you mean by establishing a connection and it's implications? also ports and tcp udp

thank you very much! great channel
