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.

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).
