The hidden network that makes the internet possible - Sajan Saini 

I’ve watched your animations since I was 6, I found your channel on my moms iPad and made it my goal to watch all of the videos you already had posted. I watched every single one of your videos every time they uploaded. Until now. I’m 12 now.

Whoa, it's almost as if this channel can answer any inquiry that comes to mind.

While we're all in lockdown and can't see each other in person, I've been video calling my dad every weekend. I'm in London and he's in Singapore, and it's almost unbelievable how little delay there is, given that it takes a person 14 hours to fly that distance.

I love this animation style! 🙃

The narrative and animate are top notch as always. Inspiring !!! Hope we get 6G sooon lol

The animation, as usual, never disappoints. It almost feels like it's getting better and better!! Every animation team understands the brief so well, and they just know what the subject matter needs. Well done again, Ted-Ed!

Informative video bro Keep up the good work

This video was accurate up until the 2:58 mark..... 1.) Most data centers moved to fiber optics between server racks years ago, with some racks using fiber optic exclusively for high bandwidth applications. 2.) "Integrated photonics" is currently a pipedream next to everyday quantum computing, way too much has to happen before we can use the technology, like figuring out how to build it. 3.) We have a technology to convert electricity to light, it's called a modem. 4.) Researchers maybe working THz tech, but we have enough issues with day to day 60Ghz wireless, to the point, it's not used commonly yet due to pitfalls. Also, the THz spectrum is approaching the visual light spectrum. You'll need more more power as you go up to get the same results, like 300x ~ 1000x the power of used by current Wi-Fi. Also, while using that much power, it won't be able to penetrate anything whatsoever. 5.) Good luck running fiber to all those nodes that will provide coverage, even if you could convince a large Telecom to pay for that bill. The FCC or equivalent government bodies would have to give up all control on the spectrum in use and where nodes could be placed. 6.) 6G, lol, come talk to me in 25 years, then maybe we'll be there. We still haven't finished 4G, the original standard called for 1Gbps, you're lucky if you can get 2.5% of that.

It still amazes me how humans managed to capture audio,photo/video and transfer them around the globe in the form of electromagnetic waves...so magical

*2:46* There's a dinosour above Australia. Lol

Making it understandable to public is a real hard work thank you so much

Thank you 🙏 so much for this video I’ve always wondered how the internet was made possible

some say the fire, wheel and electricity are the most important manmade inventions. i agree and i think the internet should be up there with them too

Thanks Ted-Ed, your videos are always so nicely presented and great to watch. New Zealand isn't on the map at 2:46...

I love TED. Every video puts me into a new perspective, whether it's a talk, riddle, or Q&A.

Keep doing what you guys do! Such a great and informative channel! These videos make my day!

I never missed any Ted Ed video, and this one is definitely one of my favorites. Thank you so much for creating this amazing content!

Wow Ted-Ed never stops amazing me. Thank you!

Incredible technology used for watching memes 🤔

Thank you for this video, because I was stuck in this topic for 2 today's and when I see is five minutes video the concept was instantly clear by this animation... Thanks a lot.

If it can make the internet possible, then it can make skynet possible

COMPUTER TECHNOLOGY + ENGINEERING + PROGRAMMING =LIFE

*2:17* This is how my television screen looks like on a rainy day

*0:49* I'm so happy on seeing that person so happy Idk why😀😊

TED-Ed , please don't change the style. Animation, background score and narration, they together give an experience of a miniature "feel-good" movie. And knowledge and information, they are bonus.

If you look from *sky* the hidden wires looks like a *net* . Hmmm. So it's a *SkyNet* 🤨

Very simplified and easy to understand explanation of how internet has spread so easily worldwide.

Amazing video, learnt this phenomenon in school recently! Great to see how this translates into real life

Great animation as always

That's a long way this video had to travel before coming to my phone

Always, always, and always a very clear & interesting narration and outstanding animation. This channel makes me addicted to watch over and over again their videos. Keep up the good work, wish someday that I'll be able to be a part of Ted Ed team 😊

Have to mention... Dr. Thomas Mensah is a world-renowned Ghanaian-American inventor and chemical engineer. Mensah is most well-known for his pioneering innovations in fiber optics and nanotechnology.

You animation is amazing 😋.

Superb animation ....!

Very excellent phyllosophy Plz make video on a topic....... Sometimes When we are watching something we realise that this scene and environment we have experienced in our past times Why this happens

Nice video ted-ed about optic fiber.. Thanks for the video..🙏

I am proud to be a human. Atleast some people from our species could able to invent such great technology.

Two facts I am critical of are: 1. the limits of fiber optics. The biggest limitation of fiber optics is “modal dispersion”. Submarine cables do not simply connect one continent with another with a single long cable. The cables are actually many short sections joined by repeaters that amplify the signal. Repeaters are required every 100 kilometers, or every 50 to 100 miles. The cables include electrical lines to power the repeaters underwater. 2. The narrator states that computer servers are overworked. This is a characterization that is both undefined and not supported. Servers infrastructure is always being upgraded as a normal part of technological demand and growth.

The animation is fantastic!

I was watching the previous video, then I found this new video just about 10 minutes uploaded. LOVE IT

I love Ted Ed because it can explain any thing.

How are there dislikes???😔 keep up the good workTed Ed love it!

Thank you Sir Tim Berners-Lee for making the internet free!!!! 👍👍👐👐

Ted...always the best

Thank you😊😊.. 3 min . Ago uploaded. .

I had no idea they were all on the ocean floor! I mean, now thinking about it, that makes sense, but still way cool!!

Love those quirky animations.

i like ted ed giving useful and unique information

Ted i have a question. What if all the people decide to sing all together. Same tiem and same day what's gonna happen. Whats the hight of the sound wave can rich

Top notch animation and narration as always. Keep up the terrific work 👍🏻

Ted-Ed always saves my sanity here in RU-vid.

Yesterday : discovered channels Today: subed I already love yall!!!

Bless the scientists who changed our world yet again.

This channel even taught me better and more than in high school !!!

Love You from INDIA✌🇮🇳

Animations, the knownledge with the narrator is so relaxing

I honestly learned much more from TED-Ed rather than school

I had this question in my mind almost forever. Thanks for answering it . I love Ted Ed. Did you also think of this question before ?? Like if you did.

Love it ❤

Please make a video about how internet cables are laid through the oceans around the world.

what an amazing video, really blew my mind

I never even considered asking how fibre optics worked. I had no idea it wasn't just a metal cable of some kind. TED-ed videos: answering questions I never had a burning need to know until the moment I see the title of the video.

THANKS TO SAJAN SAINI

About two days ago I was thinking about how does the damn internet works and boom here it is. This vid made me go like ohh my biggg god this is genius. Thanks for the vid. Keep doing this we need this

One of your greatest videos

Thanks for the good animation

You are best, as always. Love your canal

One cannot overlook the contribution of glass in this. It made possible the internet we cannot live without today..

Gotta love the animation in ted ed videos. I need to use more animation in my own videos this is inspiring

Amazing technology of optical fiber transformed the communication world. But not much is known about the inventor of process to make optical fiber, Mr. Narinder Singh Kapanny, a sikh gentleman, an another unsung hero proclaimed by Forbes magazine. I think TedEd should make video on his life and achievements.

this gonna need part 2

Further extended my knowledge on optic fibres.

Congrats on 9M Subscribers Ted Ed

This is so fascinating

I could watch this channel all day without feeling guilty cause I actually leant something.

Excellent video and superb demonstration .Bingo !!

The animation diversity is magnificent

TED-Ed answering questions I didn't even know I had!

Astounding

Nice video, worth watching...

💖 u TedEd Team

Very educational!

Finally a ted ed video I can actually understand

Incredible

Very nice explanation..

Awesome and informative video

I watch Ted Ed every single morning I’m not even close to finishing watch your videos they are incredible and very eductaional

The working of the internet has always surprised me!

WOW this is an awesome video. Learned a lot, and love the animation style :)

Yes pleaaase, more videos like this. My fav topics are food science and current technology. :O

I find Addison Anderson to be the best educational video narrator. Let's keep him busy! (Only issue: He said a "ta" instead of "to" vowel sound.)

Very nice video and informative.

This is something. Very nice video

Fiber is amazing. Love it.

amazing animation

우리가 빠른 속도의 인터넷을 사용할 수 있게 해주는 해저 케이블이 어떻게 작동하는지 새롭게 알게 되었습니다. 전기 신호가 아닌 빛을 주고받는다는 점이 신기하네요. 앞으로는 또 어떤 통신 방법이 개발될지 기대가 됩니다.

It's so good I watched 3 times

Impressive :O

Wish I could join you guys so that I can learn and also make learning possible. I've no clue how to do it....
