I know that we use radio waves to connect to the modem, but then do the wires run ALL THE WAY across the country, through the ocean, and to the country halfway around the world? And if so, how does that happen in 1-2 seconds?
In: Engineering
There are cables under the oceans that can communicate using light. The speed of light is able to circle 7.5 times around earth in 1 second and that’s how it is able to communicate in seconds.
An simplified overview would be
Your computer WiFi-> LAN to your Internet provider -> underwater cable to the Internet provider for the website -> LAN to the Website’s building -> Website’s WiFi
