The internet is not a fuzzy cloud. The internet is a wire, actually buried in the ground. Computers connected directly to the internet are called "Servers," while the computers you and I use are "clients," because they are not connected directly to the internet, but through an Internet Service Provider. Routers shuttle packets of information across the internet, and transmit e-mail, pictures, and web pages.
Before watching: "Man this video is from 2009?!"
After watching: "This video is a national treasure."
agreed
so true....
international
I agree. The best explanations are from the early days.
LOL
Pro tip : Don't skip videos just by seeing its OLD... This was so simple and easy to understand
Waow
so simple to understand
Tha famous phrase: old but gold!
ok
i’m usually more inclined to watch something if it’s old since it seems that newer videos are unnecessarily bloated up because of modern standards or something
Here from the Odin project, Great video. Wish everyone the best.
Hi, how's your progress so far?
Me too!
Same bro
same lol, good luck everyone
edit: 2 months later after this comment i decided to enlist in the navy for free college 😂, stem degree here i come…
Me too! :)
I cannot realize that it's been done 14 years ago! This video is far better than what we see today! Thanks for the great teaching!
Completely agree
When ppl couldnt rely on fancy graphics back then, they rely on being a great teacher!
When ppl overuse fancy graphics today, they forget how to teach!
youtube commenters try not to compliment a video by bringing down some imaginary strawman (99% impossible)
The Odin Project sent me here.....so glad they did. Stay curious!
Hi, How's your progress so far?

This is pretty timeless, no matter how complex the Internet may become. The basics are always there to show you the way everything works.
i get your point but i am just gonna be that guy and say the internet never changed
He really knows how to draw straight line
Because he is VERY straight 😏

It's mind boggling how he explained a complex network of computers with so much simplicity.
I really wish internet was known for stuffs like this, not for fake news, political propaganda, hate trends and all the other toxic things but for learning and making things easy.
You find what you're looking after.
I completely agree, it's so fascinating
Yes, you're right. This video is aimed at introducing the concepts of servers, ISPs, clients, etc. You're correct that in any given network topology, a single device (or a group of devices) may fill several of these roles simultaneously.
lol
Lol

:D
Aaron does the internet travel under water using deep sea cables but does it also travel under ground on land or does it travel on electrical telephone wire? The deep sea under water caper or fiber optic cable have routers attached to them that guid the packet to the right IP and server?
Thank you Aaron!!!!!!!!!!!

This is so far the simplest, clearest and I guess, best way to teach how the internet works.
meh there is a lot of stuff missing on this. and things where not described correctly
herpy derpy Yes, a lot of things were missing, there's a reason why the Internet is a work of science, it's REALLY complex. However, this is the explanation you might consider giving to a kid that just want basic understanding until he/she is old enough to learn more.
I disagree, if you really had no idea of how the internet works (which seems to be the target audience of this video) this video would lead you to believe that there is a single connection that "is" the internet and that is grossly incorrect. The internet is a web (hence world wide web or www) of networks that are all inter-connected (internet). To say that the internet is a "wire buried underground" is tantamount to saying that all of the United States water comes from a single pipe. Not to mention that he completely failed to discuss the different protocol layers in the OSI model that really define how the internet works. The video is very misleading and actually leaves its viewers not only not understanding how the internet works but actually thinking it works in a way that it doesn't.
Damnatis Malus would you be able to recommend something you'd consider acceptable for complete beginners? thanks
Buck Navich check out ua-cam.com/video/i5oe63pOhLI/v-deo.html it's a very basic level but much more informative and accurate than this video.

Or people who actually know some shit about how computer networks and Internet work. Like I counted at least 3 or 4 mistakes:
1. The Internet is NOT a bus topology (long single thick line). God have mercy on us if that was the case because we'd need forever to reach anything since our data would have to travel across millions of routers.
2. A server is NOT defined by whether or not it's connected to the Internet directly, just like a PC is NOT defined by being connected to the Internet indirectly. Server is defined by its OS version, like in case of Windows, Linux etc. (e.g. Windows Server 2016 or Ubuntu Server). Or by its role in the computer network (like a DHCP or DNS or web server).
3. aol.com is NOT an ISP. AOL is perhaps. aol.com is a DNS name (not even a web server name unless it's redirected to it). But I get it it was probably a simplification.
4. IT IS NOT THE CASE THAT EVERY ROUTER THAT FORWARDS A DATA PACKET ADDS (OR REMOVES) A LAYER THE WAY IT WAS PRESENTED HERE! Each and every data packet sent by a PC or a server consists of seven layers (aka OSI model). Yes, layers are being removed and added again in order to access some information. Like routers will remove layers 1-3 (called decapsulation) in order to access layer 3 data which includes the target IP address, among other things. But they will then add back layers 3, 2 and 1 (in this order, it's called encapsulation). Generally speaking a data packet that doesn't consist of 7 layers is invalid (unless we're talking about some specific network protocols like ICMP but it's not a case). And they claim it would be a correct one.
I get it, ok, this is simplified for sake of people who don't know a thing about computer networking or IT in general. But being simplified does not mean it can be simply incorrect and misleading. I'm sure the way the actual Internet actually works (a huge number of autonomous systems owned but different companies connected using BGP protocol) can be explained in a few minutes video and is definitely more interesting than this shit.
Still my favorite Internet explanation video. It’s always the seal of a Genius the ability to simplify a complex idea and make it look simple. A little over a decade late, but thank you for this video, Åaron Titus 👍
Very very well put. Probably one of the best explanation of the internet.. not to mention, very creatively done. I really enjoyed it. It's really funny but a lot of geeky IT people can't seem to understand the simple process of how helpful illustrations are when it comes to explaining anything.. even the most complex topic. They just throw a lot of complex terminologies at you and try to dummy down their explanation as much as they (think) they can and think that that is enough to get the point across to the people they are explaining it to. When all fails, they just blame it on you for being stupid when they are actually the dumb ones for not being able to break the explanation properly to a simple understandable level by just simply using simple and clear illustrations.. now that's not only smart but also creative. Very nice job with this video.

2023 check in. Why can't UA-camrs be this direct in our day and age? This old video is 10/10. PS hello fellow Aaron.
this video is pure knowledge, not some scammer trying to sell you something. The way education should be
I'm in an upper division ECE 4000 level course on computer networks and this is by far the most accurate depiction of how the Internet works conceptually that I've seen. I really appreciate that you went to the effort with the "wrapping" of the layers analogy as thats basically what occurs at the packet/bit vector level.
I just finished a Network Communications class and this video does a great job summing up what the internet is! It could've went into more depth of TCP and UDP but I'm glad it didn't. Short, simple, and sweet.
You're correct that the example network topology I chose to use for my illustration does not represent all possible network topologies.
14 years on and this video is still pure gold! Finest explanation I've heard by far since starting my Full-Stack Developer journey
This was added to the Odin Project, meaning it's one of the best resources to learn how to code on the entire internet. Good job.
omg, I'm 28 and used the internet basically all my life, and you just made me understand it in 5 minutes. Thank you!
How do trees access the internet?
they log in
log yourself out
What is the device which sends the packets to the servers?

Oh dammit, a good one though, cringy but good.
My pleasure. Glad to help.
Who else is here from The Odin Project?
It's very rare to find this type of teachers 😊
Thank you Aaron so much for this clear concise explanation of the internet without talking down to a non- techie like me! This was so empowering! Terrific!
If you're here from The Odin Project, congrats! Keep going!
This is a ridiculously good, simple explanation of the internet
It's December 2023 now, and still it remains one of the easiest explanations to grab on the Internet.
13 years ago. still enjoy watching it. this guy is a legend
I wish you would make more videos like this. Sure, everyone knows how to surf the web but the underlying architecture and how stuff works isn't understood by many
Wow, 10 years later and this is still an A-1 piece of content; it's aged well. Thanks for sharing 👌

Thanks for the compliment. Next time you have to give a speech on this, feel free to steal as much as you find helpful.
Thank you! Perfect explanation while still keeping it simple for newcomers. All while being done in a creative and engaging way.
Woah, I found this at 2021 :D

I literally did not find it. My teacher made me watch it lol
thank you for the video. as an ex-teacher I enjoyed very much how simple and explanatory the drawing part is made.
When you said the internet is not a cloud but a cable, it made everything click for me thanks.

+Bryan P LOL, you're actually right. when I was a kid there was this old lady who lived down the street. We'd knock on her back door and say "Aunt Ruth can we have some candy?" and she always gave us twizzlers. I don't think Ruth was her real name
+darkpearl88 ur soo ruthless
Why are old men called old man Jenkins.
This would mean there's always a Ruth in a family with multiple girls and she is single and or doesn't have kids...lol
It was released 10 years ago and still a phenomenal explanation about how the internet works.

How do I stop the internet from chopping my baby up?
Akash Menon You can't, the Internet is ruthless and has no soul.
+Akash Menon hahaha
+Shane Robinson YOU'RE describing the non human part of the Internet .
because most internet people are quite civil . many times i've had arguments in comments when months later my opposition debater responds back to me to clarify the topic or give in , or to enlighten some more . If we can transmit in light speed , there's still a social code , a reason for being here . If we can't stay within social code , the internet would be a disaster .
i'm quite proud of getting the opportunity of actually seeing it , and of the marvelous work of it's creators and technicians . remember I had to play with rabbit ears to get one more black and white channel , because we only had one , the CBC .
Bravo fellow humans , let's go where nobody has gone before .

I wonder how to connect directly to the internet... And be the self ISP...
U have to own some of the internet.
8o8inSquares that was my question too . Bypass the controllers and fees

ISPs still pay other ISPs in most cases (look up peering agreements).
The wire analogy really breaks down really quickly. In reality it's a bunch of routers reading the IP address and deciding whether to send the packet to a device (computer or router) on the network segment it manages or to a higher layer router. Eventually (after only a few hops) the highest layer router gets it and uses routing tables (generated via BGP) to send it to another ISP.
There is no magical internet, it's just a bunch of networks running the Internet Protocol which decided to peer (connect) with one another out of convenience. Who runs the individual networks? Companies, ISPs, Universities, Governments, and other institutions large enough to make a peering agreement worthwhile.

I followed Cisco's IT Essentials course, and nothing made me understand packets and such in a better way then this video has. It's been a couple months since I took the course, and I'm currently just revisiting the topics to keep sharp but this is amazing. I specifically remember never understanding how packets worked in specific, and I think I learnt more from this video.
15 years later and this is still relevant. glad I watched
WHo's here from the Odin Project??
"the internet is simply a wire!" 😂
The wrapped candy analogy is quite wrong. The only router who is likely to alter the packets is the router between you and your boss, which "unwraps" the packets and replaces the addresses (he does Network address translation (NAT)).
This router is in fact directly connected to the internet - nothing prevents you from running a server from your dsl connection.
The reason why internet is represented by a cloud is that nothing prevents the packets to be sent by other meanings than wires (satellite, mobile communication...). The RFC 1149 even specifies "IP over Avian Carriers" (IPoAC) to send Internet protocol messages over homing pigeons.
Actually, from what I know, each time a packet arrived on a router, it will alter the packet (especially for its MAC Address, this will be changed to the next router's MAC Address). CMIIW, I'm still learning
I've been working with computers for 4 years but only recently did I delve deeper into the concepts. My knowledge of the internet has been near zero until watching this video. Thank you very much!
This video is 15 years old and I’ve never heard such a clear and concise explanation !!!
Who else here came from Odin's project
the best video to know how the Internet works
MD.JHAENGR ALOM
So essentially, the internet is simply a "transportation" line and not a big box. So information I seek online is actually retrieved from a specific server with that information? Wow, cloud computing is indeed a confusing term
+Ano Nymous South Park. It was a big machine which made sense, thus I searched online to confirm and found this lol
Before I started taking classes in cybersecurity my idea of the internet was a "big box" as well. But in reality you're just accessing a company or organization's physical servers that are held in a building.

The definition of sever here is well off, it's not "a special computer connected directly to the Internet" it's any internet connected machine running web server software. My MacBook could be a server if I wanted it to.
The idea of being "directly connected" or "indirected connected" introduces a serious misunderstanding also, as well as the already spotted IP address errors. Otherwise good stuff.
wish someone sat me down and explained this the internet like this to me while I was in engineering. Learning on youtube is insanely better than learning in school. Thank you for this dowg.
This video is awesome.
Internet well explained with great visuals ✅
Thanks for the video - one question:
Why can't clients connect directly to the internet? Why do they need the ISP? Why can't they just tie into the wire that is the internet.
Also, many people use their home computers as a server for their own websites and whatnot, so in this case, is the client directly hooked up to the internet (acting like a server) and not using an ISP?
The ISP basically someone who bought a range of public IPs and industry grade equipment and absorb the cost of running the last miles of cable and customer facing issue resolution. They in turn buy from wholesalers who sell high capacity connections between ISPs. Some big ISPs are also wholesalers. ISPs also negotiate connections to other ISPs. If you don't connect to any ISP that would be called a private network.

Annotations got removed, so at 3:56:
"Note: The "Wrapped Candy" analogy is incorrect. Each IP address is directly addressable, so any router can direct your packet to any other."

Why cant just connect our pc's to the internet directly? Why do I need a service provider?
*****
Security would also be a big issue, because if you would be directly connected to the internet, you make it easy for other people to acces your PC.
***** It's an over simplification. Everyone connects to the internet via an ISP. You connect to your local ISP and they purchase their bandwidth from a larger ISP who in turn purchases bandwidth from a larger ISP. The reason you cannot just hook up to the internet directly is because you need an IP address. IP address blocks are assigned by IANA (the Internet Assigned Numbers Authority) to Regional Internet Registries who in turn assign addresses to organisations. When you sign up with your local ISP they give you an IP address that enables you to access the internet. Without an IP address computers on the internet would have no idea how to find you.
***** ISPs have routers with tens of thousands of routes using a protocol called BGP, without this service from the ISP, your computer will have no idea how to get to any of the Internets resources

How do cell phones work and how do cell phone numbers work with IP Addresses when I send texts?
+Jay Bartgis cell phones use a different kind of network for calling and texting basically they are using the phone number as your ip address remember you were able to text people before you were able to use the internet on your phone. But if you are web browsing, using e-mail, playing games, downloading aps, or whatever else you now have an ip addres from the cell network so the info knows whos phone to go to. If you are using your phone on wifi its the same except the router is giving you the ip. Some phones allow you to talk using the wifi connection for better call quality this technology is called Voip or Voice over IP similar to a skype call.
Jay Bartgis and
If you are using wifi on your smart phone and you connecting to your home router so your phone got the same ip address like your home internet
If you are using cell phone internet, my understanding is that your phone is sending the "pieces of information" to a cell tower and that cell tower is grounded to the internet via fiber optic cabling or copper. The internet is better described as a "web" than as a "cloud". The "cloud" description implies that the internet is a cloud of wireless radio waves carrying data. And while that's somewhat true, the majority of the Internet is wired. Do some google searches for "Submarine Cable Map". It's a map of all fiber optic cables that transfer data to other parts of the world. This is the true map of the physical internet. Internet through satellite communication is a minority compared to the wired part of the internet. There's a natural quarter of a second delay when using satellite communication. Also Internet provided through satellite is unreliable if there's bad weather. Satellites are only used for allowing remote parts of the world and rural areas access to the internet.
So my point is that regardless of initial connection to the internet, your data will eventually end up on a physical wire.
