# Internet
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 and information. 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.
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 and information. 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.
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).
