What a blast from the past! I can remember teaching my data processing students how to bundle data into packets so they could send information to a different computer. I haven't thought about that stuff for decades! OMG! I'm OLD!
Not yet! I'm still too busy teaching but the dinosaur jokes are getting old even if they are true. ;-) It isn't a REAL computer unless you can walk inside it to fix it.
It's not just a ping package. Ping is just an icmp function that sends a small package and hopefully gets a reply. When you try to go to youtube, you first have to look up the ip address via a dns request, then open a tcp connection to said address, load the page presented, and then repeat the process for all other domains and pages associated (like adsense stuff etc). On top of that, your browser might ask other websites if the site you're going to is known safe, check certificates and plugins like adblock or a translator might have to process the page - all of that before you're actually seeing a page. It could very well take half a second.
Olivia is cute in this video :D SciShow is all about science and we debate logically. Hating Olivia w/o any reason just makes you look irrational and irrational ppl are, I believe, not welcomed in SciShow. It's not cool hating on her and its not cool being edgy by hating on her. I don't mind who is hosting as long as the host presents the content well.
yeah i have no problem with her as a person i just find the way she speaks uncomfortable and distracting, but i think i now have a solution for me anyway, mute the video and turn on closed captions.
Im a network engineer and it really fascinates me how it all began. The internet was revolutionary we all use it every single day. Our world’s infrastructure wouldn’t work without it
There is a small mistake the DNS (Domain Name System) server only translates domain names to ip addresses for example if you want to connect to youtube your computer would ask a dns and the dns would reply with youtube ip address then your computer will use that ip to connect to youtube what you talked about is routing and it is usually handled by switches, routers, gateways, bridges ... where your computer would send the packets to your home router that will send them to your ISP, and then your ISP would send it to the destination if it is on the same subnetwork or another ISP if it is on another network
came here to say the same thing. routing is entirely different (and way way more complicated than DNS). there are tons of routing protocols, and different ones are used in different parts. BGP is the main one in use on the internet, but your home router uses something else entirely.
Though it was generally correct. I doubt we're getting into the OSI model here.... There are also more than A records in dns (which is what was referred to in the video - in fact, I'm pretty sure MX records existed in the late 80s which was the other example). Oh and per the RUclips example, there's a high chance that an AAAA record is what was used to find the server.
There were a few conceptual inaccuracies, but in general the information was good. :) For example, the DNS doesn't take care of everything, it just resolves the host name to the destination's IP address, then your computer sends out the packets with that IP as the destination and all of the intermediary routers (using the router interface protocol) know how to route your packets based on the IP. At this point it switches from top level and 2nd level domains to network classes, so 145.x.x.x is a class A, 145.23.x.x is a class B, and 145.23.189.x is a class C network. Along with those network classes, there is subnetting (netmask) along with routing tables lets the router know where to send the packet. The 4th number in the IP address is the individual computer (host / server / workstation / router / DNS server / etc). Then you have default gateways, network gateways, etc. But DNS servers and routers are generally different hardware and perform different functions.... umm... sorry... lots of information, and that's just scratching the surface. I can understand why you wouldn't include that level of detail, because it just gets confusing trying to keep up with two dynamic layers that are essentially cooperating to accomplish a single goal. Not to mention that most people don't care and don't need to know. I've been in technology as a career since 1990, when I joined the US Army and was trained in voice and data network hardware and software. Back then HTTP was still a fledgling protocol, and web browsers weren't really a thing yet... telnet was everything... but I digress. :) Good episode, I can't wait for the next one!
Mostly accurate comment. As you note, packet routing, DNS lookups, and email routing are all entirely different concepts. Two coments however: One, when classfull routing was still used in the last 1980's, each class started with a different octet. 1.x.x.x to 63.x.x.x were class A, 65.1.x.x to 126.255.x.x were class B, and 128.1.1.x to 223.255.255.x - and two, classful routing hasn't been in use on the Internet backbones since the late 1980's. Google "CIDR" if you want to learn more.
Another is not getting the distinction between TCP and IP right. TCP doesn't even really belong in there, it's just IP. And part of the IP protocol is its addressing scheme. TCP is just a way to allow you to pretend you have something like the hard-wire phone line when talking over a packet-switched network.

You guys are annoyed by Reid Reimers then too, right? Because he sounds exactly the same as this woman. "wahh she's too high pitched i'm so triggered" Read up on dialects. It's called inflection. She's using it in this case the simplify things down so that the broader audience has an easy time understanding what she's saying.

You kinda breezed through the 80s. I remember using Bitnet back in the 80s at school for email, usenet, ftp, forums, games, etc. Bitnet was sorta a civilian version of arpanet.
Two corrections TCP/IP isn't a program, it's a protocol; a set of rules that something has to adhere to. And you described a gateway, not a DNS server. So your computer polls a DNS server to translate the URL into an IP address and sends the packet to his gateway, which sends it further along the way till it reaches its destination or depleted it's TTL
As a network engineer by-day, I think this was a fairly good introduction for the lay person. I should share this with my less savvy friends and family to see how they understand it!
Well done. Thank you for posting. Your research is historically accurate. I came of age before the Internet was introduced during 1989. I would have loved to have learned about ARPA in 1969 and the birth of email in 1971 when I was a small child.
Twisted World No, I just think the individuals who defame her for superficial reasons don't understand what makes an effective speaker in the sciences.
youknowit789 First of all, the original comment in this thread has been deleted--perhaps it was gratuitously cruel. But, much as I wanted to watch it, I had to turn this video off in its second minute. This young woman made it unwatchable. I went immediately to the comment section to see if I was being unfair, or if anyone else had had the same experience as me, and I found this censored thread. Look, this is something I know a little about: I trained as an actor and director at American Repertory Theater, Harvard's drama school. I'm sure she's a nice, young woman, but the idea that she is an effective presenter is ludicrous. The constant bobbing of her hands, as she performs the watusi to some unheard drum solo, makes this video one of the most annoying things I've ever seen. All while she reads from a prompter in a way that calls attention to itself. This is an audition tape that has gone horribly wrong. Completely unwatchable.
i actually think she's a great presenter. I don't care enough to compare the presenters, because why they hell should I? What's important is the content, not the presenter themselves... This is a channel the revolves around science and learning. So long as the quality of the information presented doesn't change, i don't see any justifiable reason to complain.
Super excited that I found this series! I am a home-schooling mama of four children varying from third grade all the way up to ninth grade, and for our inventions school topic this week we are doing the internet. So scourong on RUclips for the perfect video was my task this am. 😃 Your video was the 2nd I came across... I like the fact that you seem relatable, and I feel that my children are going to enjoy this video today. I always watch the videos beforehand to make sure it's something that I know ALL of the children can get into, and I really feel this will do the job! Not to mention, I was interested in what you were saying the entire time LOL. So, thanks! ✌ 💘 😊 to your and yours!
At 7:33-7:46, Olivia is wrong about the differences between TCP and IP. In fact, _both_ TCP and IP specify parts of the TCP/IP packet structure. But TCP also enables two computers to exchange data reliably over a connection. TCP also allows multiple programs to connect to the Internet from the same machine by using one of 65,536 software-defined ports. (TCP can be swapped out for UDP, which has its own set of ports but doesn't ensure reliability.) Other than that, great video! :)
Aidan Fitzgerald idk the differences were mentioned. But yeah, saying that the Internet is run on two protocols is wrong. TCP/IP is used to refer to the suite of protocols that are used on the Internet. Wrt referring to it as a program, it kinda was (winsock anyone?). Point being, until Windows 95 (B IIRC) and (again IIRC) OS/2, non-Unix operating systems didn't natively support networking. And there was a bit of a fight between IPX/SPX (remember Novell? Still around and selling GroupWise and the like) and TCP/IP - and mainframes spoke / speak different protocols altogether (thanks IBM - see TN3790 for an example of how different that is). Point being, even if you had network support, you didn't necessarily have the ability to connect to the computer you were looking for - it was still segmented until the mid 90s. Also, BBSs, and AOL, CompuServ, and Prodigy should really be mentioned along this time.
I suspect, it wouldn't be so bad if the video wasn't composed entirely of 1 sentence takes. I am guessing she does not sound like that in a continuously cut.
Nice work Olivia ! Presenting these details coherently is not one of the easiest things to do and I applaud you and the team on pulling this one together well.
SciShow Fantastic mini-series. The explanation was spot-on. Im really looking forward to watching all of it! It's awful reading the comments under this video, but despite hate and misogyny, you're doing a great job.
I know how the internet works. A person made a coding language that is called HTML Hypertext Markup Language. and CSS Cascading stylesheets and JS JavaScript
"One of ARPAnet's first big innovations was what's known as Packet Switching" Whoa! Neither Leonard Kleinrock, who first provided a detailed theory of switching, nor Paul Baran and Donald Davies, who created packets, were members of ARPA.
That's true- but one reason why it became necessary for Kahn & Cerf to invent TCP/IP was that ARPANET was not the only packet-switching network being developed following Davies' 1966 proposals; it just happened to be the first to come onstream.
Millions of years later, after all this hard work, some nut will come along and dispute the creation of the internet, insisting it originated with a bang. A Big Bang.
This video has represented the history of the Internet in a way normal people can understand and apprehend the technical terms. All the information mentioned in the video tells an accurate story.
IP is a standard way of formatting packets and yes, it also defines an address system, but TCP sits on top of IP to provide stream based services - similar to creating virtual circuits on the IP network - but IP is what provides a lowest common denominator for packet formats and not all traffic on the internet uses TCP (UDP for example), however it all uses IP.
Niels van hoof from which only hank and michael have their own channel, which might suggest Olivia is actually one researcher that took also the task of presenting some of the episodes. Actually, the other girl that comes to present from time to time is in fact from the research team.
On friday i visited CERN and I saw the server that Tim Berners-Lee used when he created the WWW. I didn't realise it was still at CERN and it's kept in this 'globe' which is really dark inside, and it's near the corner. When I first of all looked at it i had to double take because it seemed out of place with the other displays in the room and there wasn't anything to advertise it being in that room.
Hi there, SciShow! I would love for people to learn about the terrifying and sudden nature of cerebral aneurysms! I had one rupture at 19 and I think it would make for an interesting video topic!
_"From one PC to another, another PC to one. The packet of one it´s destiny singled out alone, reached"_ _"From all PCs together, with a common protocol shared. With the mapping of their sites made one DNS, there is an Internet without end!"_ *"."*
@@WalterWhite-pr1qs Nope. He invented WWW, or the whole concept of web browsers and web pages. The Internet is the whole thing ARPA was working on, connecting computers in a colossal net.
I very recently did effectively the very same research lately, and to nearly the same level of detail throughout, starting with Babbage but not into so much detail as protocols, but instead with a focus on hardware.
Minor point: the DNS doesn't "do the rest". All you do is ask it where youtube.com is and it tells you where, then your computer will communicate with that address on its own
Finally? She sucked at start and deserved her dislikes. She still has a super annoying voice and way of talking, and should imo not be a presenter. But she has improved, so you could say: Finally, she has improved a bit, and thus she deserves less dislikes, but it's still not good enough.
Can you imagine how cool it would be to set in a room with all these ppl figuring out how these problems would be solved and all the ah ha moments!!! Just set there and watch and listen.
The PSTN hasn't been circuit switched for decades. After becoming digitized, there has not been a need for circuit switching. Strowger and crossbar switches at this point are museum pieces. If anything, the phone system is cell switched (see ATM), although significant parts are now VOIP.
Great video, and nothing personal, but i really dislike her voice. She is clearly very intelligent and well spoken, but her voice is very grating on my ears, and makes watching her uncomfortable. Considering this is a video series, I think its kind of important to have hosts with more pleasing voices...
10:33: Everything was great up until this point. DNS servers don't route packets. Instead, they allow your machine to query for information about a domain, including the address of the machine (the A and AAAA records). This address is included in the IP/IPv6 packets that form the parts of the message, allowing it to be relayed onto its ultimate destination. But no, the DNS server doesn't 'do the rest': it's akin to a phone directory and that's it.
They're called Routers and are owned by your ISP, other network operators (who run the networks that interconnect everything), and eventually some owned by Google, where finally the server holding your video lives. My company just established a direct link to Google last fall, so on my network, it's my routers, then Google's.

Aidan Fitzgerald idk the differences were mentioned. But yeah, saying that the Internet is run on two protocols is wrong. TCP/IP is used to refer to the suite of protocols that are used on the Internet.
Wrt referring to it as a program, it kinda was (winsock anyone?). Point being, until Windows 95 (B IIRC) and (again IIRC) OS/2, non-Unix operating systems didn't natively support networking. And there was a bit of a fight between IPX/SPX (remember Novell? Still around and selling GroupWise and the like) and TCP/IP - and mainframes spoke / speak different protocols altogether (thanks IBM - see TN3790 for an example of how different that is). Point being, even if you had network support, you didn't necessarily have the ability to connect to the computer you were looking for - it was still segmented until the mid 90s.
Also, BBSs, and AOL, CompuServ, and Prodigy should really be mentioned along this time.
Aidan Fitzgerald Also "software defined ports" is better stated as kernel memory.
Been calling it "TCP IP" for nearly 20 years. I guess it's technically not wrong to say the slash, but it sounds really strange to me.
I know this isn't a trendy thing to say, but great job, Olivia!
I like it. I've been taught a lot about internet history before, but this approach seems fresh and relevant.
The way she pronounces every sentence as if it's a question makes this video actually pretty hard to understand
I suspect, it wouldn't be so bad if the video wasn't composed entirely of 1 sentence takes. I am guessing she does not sound like that in a continuously cut.
Called upspeak, should fix that.
True
That's right. Only I could listen her 1 minutes !
she also starts most sentences like its a question
Intro was exactly what I was asking. Thanks. Stayed for the whole thing
0:50 - 1:10
So thats the reason why i can replay the video to the point it stopped because my internet went oof
Good job, Olivia.

She did a terrible job
Nice work Olivia ! Presenting these details coherently is not one of the easiest things to do and I applaud you and the team on pulling this one together well.
SciShow Fantastic mini-series. The explanation was spot-on. Im really looking forward to watching all of it! It's awful reading the comments under this video, but despite hate and misogyny, you're doing a great job.
Ouch. My ears.
〈Insert name here〉 seen this feller with holes so big u could swing from em. why u think fools want long dangly earlobes for
Recommend you consider using a lint roller before recording.
Olivia, you're brilliant.
Ta hell with the haters. Love your presentation and knowledge.
Jeremy Ellwood You horny dog
Love it! Keep these and other mini-series coming :D
I know how the internet works.
A person made a coding language that is called HTML
Hypertext Markup Language.
and CSS
Cascading stylesheets
and JS
JavaScript
A series about the history of operating systems and the capabilities they had at those times would be cool.
Myes myes. It would be cool.
I Just Realized..The Internet Was Made Without Internet..
Someone needs a lint roller.
WE DID NOT INVENT INTERNET. WE DISCOVERED IT!
i didn't even know this topic interested me until i watched this. cool stuff!
Well put, Olivia. Can't wait for the next part.

"One of ARPAnet's first big innovations was what's known as Packet Switching"
Whoa!
Neither Leonard Kleinrock, who first provided a detailed theory of switching, nor Paul Baran and Donald Davies, who created packets, were members of ARPA.
PastPresented But those were just papers. Not actual hardware in use IIRC
That's true- but one reason why it became necessary for Kahn & Cerf to invent TCP/IP was that ARPANET was not the only packet-switching network being developed following Davies' 1966 proposals; it just happened to be the first to come onstream.
I could listen to her talk all day and not feel I wasted a moment. Just magnetic
This was great - looking forward to the next episode! 😊
Millions of years later, after all this hard work, some nut will come along and dispute the creation of the internet, insisting it originated with a bang. A Big Bang.
I was getting hooked and it suddenly ended! I love the host though
This video has represented the history of the Internet in a way normal people can understand and apprehend the technical terms. All the information mentioned in the video tells an accurate story.
I miss Hank Green narrating.
If I were presenting a video for a channel with over 4 million subscribers.....
I'd wear a clean shirt.
cool video, looking forward to the next. :)

IP is a standard way of formatting packets and yes, it also defines an address system, but TCP sits on top of IP to provide stream based services - similar to creating virtual circuits on the IP network - but IP is what provides a lowest common denominator for packet formats and not all traffic on the internet uses TCP (UDP for example), however it all uses IP.
Intelligent women are great
Niels van hoof from which only hank and michael have their own channel, which might suggest Olivia is actually one researcher that took also the task of presenting some of the episodes.
Actually, the other girl that comes to present from time to time is in fact from the research team.
Intelligent people are great
delte
Stupid women are great too :)
I just don't understand why she sounds out every sentence like a question. Are you asking me the history of the internet or telling me?
On friday i visited CERN and I saw the server that Tim Berners-Lee used when he created the WWW. I didn't realise it was still at CERN and it's kept in this 'globe' which is really dark inside, and it's near the corner. When I first of all looked at it i had to double take because it seemed out of place with the other displays in the room and there wasn't anything to advertise it being in that room.
Hi there, SciShow! I would love for people to learn about the terrifying and sudden nature of cerebral aneurysms! I had one rupture at 19 and I think it would make for an interesting video topic!

Two Americans Robert E kahn and vint cerf invented the Internet literally
One British man actually!
@@WalterWhite-pr1qs Nope. He invented WWW, or the whole concept of web browsers and web pages. The Internet is the whole thing ARPA was working on, connecting computers in a colossal net.
@@TheBucketSkill stupid Brits...they have no IT sector or computers. They buy American 😂
YESSS! I've been for you guys to make a video about this!
Nooooooo not the end ! I want the next part right now... it's so hard to wait !
I'm 99% sure the only reason people know what DARPA is is because of Metal Gear Solid
i didn't think i would find this topic very interesting but i was definitely wrong! thanks olivia!
To be exact, when it "jumped the pond" it connected to Norway first, then England a few days later.
This part one is great! ..waiting for the next one.
Great first episode in this series Olivia, really liked it and looking forward to the rest.
Good Video SciShow. One question though: Is Olivia wearing a (Mini) USB Ear ring? At least the bottom end of it looks like a USB Connector
I'm glad Olivia is doing this series.
Also, it goes well with Crash Course Computers.
The next episode should be titled, the keyholders of the internet ;)
The more complex the topic, the more animations/visuals are needed.
I very recently did effectively the very same research lately, and to nearly the same level of detail throughout, starting with Babbage but not into so much detail as protocols, but instead with a focus on hardware.
Come on SciShow, ya'll have left me hanging for weeks now! What happened to the Internet? Did it ever find true love?
god i hope you part two starts with Tim Berners-Lee , the inventor of the world wide web
This is the kind of video I enjoy seeing from SciShow. :)
Great video guys! Such an interesting topic, cant wait to see more of the series. Hope Olivia does the rest, shes a wonderful host :)
Jsi jedna z nejsluníčkovatějších sluníček. :)
And people swear Americans didn’t invent the internet 😂
Minor point: the DNS doesn't "do the rest". All you do is ask it where youtube.com is and it tells you where, then your computer will communicate with that address on its own
When I'm on gta online, it took forever to find others players.😥
Olivia is my new favorite SciShow host.
>look at like/dislike ratio
Ah, I wonder who is hosting.
it seems to be dying down though
finally
Finally? She sucked at start and deserved her dislikes. She still has a super annoying voice and way of talking, and should imo not be a presenter. But she has improved, so you could say: Finally, she has improved a bit, and thus she deserves less dislikes, but it's still not good enough.
Can you imagine how cool it would be to set in a room with all these ppl figuring out how these problems would be solved and all the ah ha moments!!! Just set there and watch and listen.
Which people
10:29 ... "had long since accomplished it's goal so they decided to spy on it."
There. Fixed it for you.
what was the first meme?
A meme is something that spreads through a population that's not genetic, so.. sex maybe?

sadly, sex is genetic.

Is there a USB stick on her earring? Nice video BTW!
this vid gets more important every day, because you cant be sure that they teach this in schools
Very interesting!

The PSTN hasn't been circuit switched for decades. After becoming digitized, there has not been a need for circuit switching. Strowger and crossbar switches at this point are museum pieces. If anything, the phone system is cell switched (see ATM), although significant parts are now VOIP.
Great video, and nothing personal, but i really dislike her voice. She is clearly very intelligent and well spoken, but her voice is very grating on my ears, and makes watching her uncomfortable. Considering this is a video series, I think its kind of important to have hosts with more pleasing voices...
EpicNational I like her voice
I have no problem with her voice...must be your own skull's resonance frequency...
oh man I thought I was the only one. i agree her voice sounds annoying.
I like her voice very much.
I'm getting tired of seeing this comment. All that matters is if she's engaging and knowledgeable, not how much it pleases your ears.
10:33: Everything was great up until this point. DNS servers don't route packets. Instead, they allow your machine to query for information about a domain, including the address of the machine (the A and AAAA records).
This address is included in the IP/IPv6 packets that form the parts of the message, allowing it to be relayed onto its ultimate destination.
But no, the DNS server doesn't 'do the rest': it's akin to a phone directory and that's it.
Keith Gaughan it's not *intended to* route packets. You can store a lot of info in a TXT record and get dns to do lots :)
Love the video. I've always wanted to know more about how the Internet works. I always wondered who owns the servers between my computer and RUclips.
William Stockhecker +
They're called Routers and are owned by your ISP, other network operators (who run the networks that interconnect everything), and eventually some owned by Google, where finally the server holding your video lives. My company just established a direct link to Google last fall, so on my network, it's my routers, then Google's.
Nice to see some love for Olivia in the comments. I never did understand the hate.
You did a great job with the video!
