): the Internet belongs to the People. However, no; we would not be able to "shut down the Internet" if we wanted to.
It was a perfect invention. But that's just the thing: It is less of an "invention" and more of an "idea".
Anything that connects to something else is "networked" together. Usually called a "PAN" - _P_ersonal _A_rea _N_etwork; they can therefore be linked to a MODEM (MOdulator-DEModulator) which connects to a MAN (municipal area network) and then a WAN (wide-area network) -> which is connected to a whole fleet of "back-stage" machines (servers) which collect and display stuff (web pages, videos, etc.) and translate "Human-Code" - human language - into computer languages.
Therefore, an "Intranet" is a any of these networks that aren't open to alien connections. [ You need to register at this hotel to access the network." ]
Ah shit man just... know that the "Internet" cannot go down - by anyone.
It simply isn't sophisticated enough.
