Internet is the grand, [decentralized](decentralization.md) global network of interconnected [computer](computer.md) [networks](network.md) that allows advanced, cheap, practically instantaneous intercommunication of people and computers and sharing of large amounts of [data](data.md) and [information](information.md). Over just a few decades since its birth in 1970s it changed the society tremendously, shifted it to the information age and stands as possibly the greatest technological invention of our society. It is a platform for many services and applications such as the [web](www.md), [e-mail](email.md), [internet of things](iot.md), [torrents](torrent.md), phone calls, video streaming, multiplayer [games](game.md) etc. Of course, once Internet became accessible to normal people and has become the largest public forum on the planet, it has also become the biggest dump of retards in history.
Sometimes we distinguish between lowercase *i* "internet", meaning a large computer network, and capital *I* "Internet", meaning the one, biggest worldwide internet. As many networks just become part of the great Internet, we see this distinction less often and without saying otherwise, in normal speech both "internet" or "Internet" typically stand for the big Internet.
Internet is built on top of [protocols](protocol.md) (such as [IP](ip.md), [HTTP](http.md) or [SMTP](smtp.md)), standards, organizations (such as [ICANN](icann.md), [IANA](iana.md) or [W3C](w3c.md)) and infrastructure (undersea cables, satellites, [routers](routers.md), ...) that all together work to create a great network based on **[packet switching](packet_switching.md)**, i.e. a method of transferring digital data by breaking them down into small [packets](packet.md) which independently travel to their destination (contrast this to [circuit switching](circuit_switching.md)). The key feature of the Internet is its **[decentralization](decentralization.md)**, i.e. the attribute of having no central node or authority so that it cannot easily be destroyed or taken control over -- this is by design, the Internet evolved from [ARPANET](arpanet.md), a project of the US defense department. Nevertheless there are parties constantly trying to seize at least partial control of the Internet such as governments (e.g. China and its [Great Firewall](great_firewall.md), [EU](eu.md) with its "anti-pedophile" chat monitoring laws etc.) and corporations (by creating centralized services such as [social networks](social_network.md)). Some are warning of possible de-globalization of the Internet that some parties are trying to carry out, which would turn the Internet into so called [splinternet](splinternet.md).
Access to the Internet is offered by [ISPs](isp.md) (internet service providers) but it's pretty easy to connect to the Internet even for free, e.g. via free [wifis](wifi.md) in public places, or in libraries. By 2020 more than half of world's population had access to the Internet -- most people in the first world have practically constant, unlimited access to it via their [smartphones](smartphone.md), and even in [poor countries](shithole.md) [capitalism](capitalism.md) makes these devices along with Internet access cheap as people constantly carrying around devices that display [ads](ad.md) and spy on them is what allows their easy [exploitation](leading_the_pig_to_the_slaughterhouse.md).
The following are some stats about the Internet as of 2022: there are over 5 billion users world-wide (more than half of them from Asia and mostly young people) and over 50 billion individual devices connected, about 2 billion websites (over 60% in [English](english.md)) on the web, hundreds of billions of emails are sent every day, average connection speed is 24 Mbps, there are over 370 million registered [domain](domain.md) names (most popular [TLD](tld.md) is .com), [Google](google.com) performs about 7 billion web searches daily (over 90% of all search engines).
PRO TIP: **you should print your own offline Internet** (or maybe we should rather say offline [web](www.md)). Collect your favorite websites and other resources (gopher holes, Usenet threads, images, ...) and make a single dense [PDF](pdf.md) out of them. Process each page so that it's just plain text, remove all graphics and colors, unify the font, make the font small and decrease margins so that you fit as much as possible on a single page to not waste paper. For many pages, like Wikipedia, a small script will be able to do this automatically; the uglier pages may just be edited manually. An easy approach is for example to convert the pages to plain HTML that just contains paragraphs and heading of different levels, then copy-pasting this to LibreOffice, globally editing the font and auto-generate things like table of contents and page numbers, then exporting as PDF. You can even make a script that contains the list of pages you want to scrap so that you can make a newer print a few years later. Once you have the PDF, print it out and have your own tiny offline net :) It will be useful [when the lights go out](collapse.md), it's a physical backup of your favorite sites (the PDF, as a byproduct, is also a single-file backup in electronic form), something no one will be silently censoring under your hands, and it's also just nice to read through printed pages, the experience is better than reading stuff on the screen -- this will be like your own 100% personalized book with stuff you find most interesting, in a form that's comfortable to read.
