Co je to Internet?

What is the internet?
Co je to ten Internet?
The internet is like a popular thing.
Internet je ta populární věc.
Some satellites up there.
Nějaké satelity na obloze.
I picture it in my head with like waves of internet going to the phone.
Já si to představuju jako vlny internetu, co tečou do telefonu.
Somebody told me a cloud once.
Někdo mi říkal, že to je mrak.
The internet is a lot like plumbing it's always moving.
Internet je jako potrubí, stále v pohybu.
Most people don't have any idea where the internet came from and
Většina lidí nemá ponětí, odkud se Internet vzal
doesn't matter, they don't need to. It's sort of like asking who invented the
a ono na tom nezáleží, nepotřebují to. Je to jako ptát se, kdo vymyslel propisku,
ballpoint pen, or the flush toilet
nebo splachovací záchod nebo zip.
or the zipper. These are all things we just use every day we don't even think about the fact
To jsou věci každodenní potřeby a my už ani neuvažujeme o tom,
that one day somebody invented them.
že je kdysi musel někdo vynalézt.
So the internet is just like that. Many, many years ago in the early 1970s
S Internetem je to stejné. V sedmdesátých letech
my partner Bob Kahn and I began working on the design of what we now call the internet.
jsme s mým partnerem Bobem Kahnem začali na návrhu něčeho, čemu teď říkáme Internet.
It was a result of another experiment called the ARPANET
Byl to výsledek jiného experimentu zvaného ARPANET,
which stood for Advanced Research Project Agency Network. It was a Defense
neboli síť agentury pro projekty pokročilého výzkumu (Advanced Research Project Agency Network).
Department research project.
Byl to výzkumný projekt ministerstva obrany.
Paul Baran was trying to figure out how to build a communication system that might actually survive a nuclear attack.
Paul Baran zkoumal, jak vybudovat komunikační systém, který by mohl přežít jaderný útok.
So he had this idea of breaking messages up into blocks and sending them as fast
Tak přišel s nápadem, jak rozebrat zprávy na malé bloky
as possible in every possible direction through the mesh network.
a ty posílat co nejrychleji všemi možnými směry v rámci sítě připomínající pletivo.
[whoosh] So we built what eventually became a nationwide experimental packet network, and it worked.
Takže jsme postavili pokusnou paketovou síť a ono to fungovalo.

Is anybody in charge of the internet?
A kdo ten Internet řídí?
The government controls it.
Státní orgány ho řídí.
Elves, obviously elves!
Skřítci, jednoznačně skřítci!
The people to control the Wi-Fi because then no Wi-Fi, no internet.
Lidi, co ovládají wi-fi, protože bez wi-fi není Internet.
T-mobile, um, Xfinity,
T-mobile a... Xfinity.

[pauza]
Right?!
Že jo?
The honest answer is well nobody and maybe another answer is everybody.
Po pravdě ho neřídí nikdo anebo naopak my všichni.
The real answer is that the internet is made up of an incredibly large number of independently operated networks.
Ve skutečnosti je Internet tvořen obrovským počtem nezávisle řízených sítí.
What's interesting about the system is that it's fully distributed. There's no
Je zajímavé, že se jedná o zcela decentralizovaný systém.
central control that is deciding how packets are routed or where pieces of the network are built
Neexistuje centrální řízení rozhodující, kudy který paket putuje, kde se postaví části sítě,
or even who interconnects with whom.
nebo dokonce kdo je propojen s kým.
These are all business decisions that are made independently by the operators.
To vše jsou rozhodnutí nezávislých aktérů.
They are all motivated to assure that there is end-to-end connectivity of
Je v zájmu všech, aby fungovalo spojení odkudkoliv kamkoliv
every part of the network because the utility of the net is that any device
mezi všemi částmi sítě, protože hlavní přínos sítě je, že jakékoliv zařízení
can communicate with any other device; just like you want to be able to make
může komunikovat s jakýmkoliv jiným - stejně jako se chcete z jednoho telefonu
phone calls to any other telephone in the world.
dovolat na kterýkoliv jiný na světě.
There's nothing like this that has ever been built before.
Nic podobného nebylo nikdy dříve postaveno.
The idea that what you know might be useful to somebody else
Myšlenka, že to, co víte, se může hodit někomu jinému
or vice versa is a very powerful motivator
anebo obráceně, je silnou motivací pro sdílení informací.
for sharing information. By the way that's how science gets done, people share information.
Mimochodem, tak funguje i věda - lidé sdílejí informace.
So this is an opportunity for people to think up new applications,
Čili toto je příležitost pro lidi, aby přišli na nové uplatnění,
maybe program them as apps on a mobile phone, maybe become part of the continued growth of the infrastructure of the
třeba v podobě mobilních aplikací, nebo v rozšiřování infrastruktury celé sítě,

aby se dostala i k lidem, kteří k ní zatím nemají přístup.
of it on a day-to-day basis.
A nebo v jejím každodenním používání.
You can't escape from contact with the internet so why not get to know it and
Kontaktu s Internetem neuniknete, tak proč se s ním neseznámit a nezačít ho používat?
use it. [swirling sound effect]
