As a 20-year veteran of working as a network engineer, currently on the backbone for Super Huge Major Telecom, Inc., I heartily endorse this video. It is as succinct, accurate, and accessible as anything I've ever seen.

Two Professors with PhDs in computer science spent 6 hours in lectures trying to explain this in my Master's lectures. You guys did it in 12 mins, phenomenal!

The video is totally worth watching!
Now i get it:
IP - is simply what and where to send
UDP - on top of IP provides ports and packaging but does not ensure the delivery, just informs when the data is corrupted
TCP - on top of IP also provides ports and packaging, but insures the delivery (thus increasing the network load)

I am now 38 years old and I am learning Python. I tried to learn programming early, but despite all my efforts this opportunity was not given to me in my country. Despite all the obstacles I have never given up on this dream and now I am more motivated than ever to learn from the precious help of the internet. Luckily there are many bright people here who kindly help anyone looking to learn computing. Although very difficult, I hope that one day I will become a programmer.

Wow, so much work has been put into this video, and all for the purpose of spreading knowledge didactically! You guys are awesome, please keep up the excellent work!

I've been computer science since childhood (for about 25 years now) and I haven't seen such a great explanation of Internet and especially ISO/OSI standards. However I had take exams of these during my university years. Thanks for making this video and please make more videos like of this. :)

Who knew so much thought went into distributing cat videos?

I could tell you a joke about UDP, but you might not get it.

[splooshmccooch]

I know absolutely nothing about computers besides clicking the thingy to get the stuff and thought it was just magic but I love this series and have binge watched it all. Now I actually have a basic understanding on how all the components do relatively simple jobs to make everything happen and why things are the way they are. Now I just think it's magic that it was thought up by somebody in the first place. Awesome show and please keep them coming

I'm taking CCNA (Cisco Certified Networking Associate) and this video would have really been helpful as an introduction to the course.

The Cisco site really should link to your video.

As a non-cumputer person, thank you very much for this whole series !

[sibtiali]

This video single-handedly made me understand more about networking than a whole year of my university module.

[olivierbegassat]

Everyone involved in this : thank you ! This series is AMAZING !

[yt_chill]

This video sums up my entire networking course in a thousandth of the time. Truly amazing stuff, I absolutely love the level of detail that goes into these videos!

But I thought the Internet was a black box with a red light on top. MY LIFE IS A LIE.

[jlupus]

Jokes on you- I didn’t stream this. I sent someone to download this video, burn it on a disk, then play it for me off an old portable DVD player. Now he’s writing this comment for me. Checkmate, computer lady.

[bipolarpenguinmusic]

The production of this is amazing, explained so well from scratch. I am honestly impressed, thank you so much for this!

Here's a practical question...why is it not recommended to type sensitive information (passwords, card numbers) on public networks (coffee shop or airport), like how exactly can someone view that info?

[filipfilipovic]

Hmm... I tried doing traceroot for dftba.com from Serbia. It took me only 8 hops and my latency was lower than Carrie Anne’s. Didn’t expect I had such a good connection.
