In simple terms, the transmits information from point A to point B. These points are IP addresses – unique codes that identify the location of devices around the world. But any information passes through the data servers that are in the processing centers.
The easiest, fastest, most reliable and affordable way to transfer information is through cable. The Internet relies almost entirely on cables. The problem is that many of these cables pass through water. This makes their packing very long, complicated and expensive. This process took almost 200 years. To date, more than 300 submarine cables with a total length of almost 900 thousand kilometers have been laid. 97% of all intercontinental data is transmitted through these cables, and if they are stacked one to one, they can be stretched from Earth to the Moon and three more times wrapped around the Earth.
