FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The physical network Between countries and continents, the internet is distributed via a vast series of undersea cables. Within countries, smaller cables run underground until they eventually branch into each of our homes.

Detailed explanation-2: -Subsea or submarine cables are fiber optic cables that connect countries across the world via cables laid on the ocean floor. These cables – often thousands of miles in length – are able to transmit huge amounts of data rapidly from one point to another.

Detailed explanation-3: -Not many people realize that undersea cables transport nearly 100 percent of transoceanic data traffic. These lines are laid on the very bottom of the ocean floor. They’re about as thick as a garden hose and carry the world’s internet, phone calls, and even TV transmissions between continents at the speed of light.

Detailed explanation-4: -Undersea cables are responsible for moving data between countries and continents at high speeds, making everything from photo sharing to financial transactions possible. These cables use fiber optics to move data at high speeds to land, where the data is then conveyed via fiber optics to homes and businesses.
