00:00:00 - 00:05:00

The video discusses the different submarine cables that are used to connect different parts of the world. It explains how these cables are able to transfer large amounts of data and how they are protected against failure. The video also highlights some of the places where these cables have not yet reached.

• 00:00:00 Internet cables are small and thin, and are coated with seven layers of protection to reduce the chances of failure. They are incredibly efficient in their ability to transfer large amounts of data, and are used to connect different parts of the world.
• 00:05:00 The southernmost cable in the world connects Tierra del Fuego with Santa Cruz on the mainland of Argentina. Other Argentine networks reach a small coastal town called Las Toninas. If one travels to the other end of the map, one of the most striking connections is the one that goes from northern Norway to the Svalvard archipelago. However, the connection has more than 1300 kilometers, and only 2500 people live in the archipelago. Similarly, there are several places in which the cables do not arrive yet. For example, Easter Island, the Galapagos Islands and the Falklands.
