FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Currently, 98% of international internet traffic flows through undersea cables, according to Google data: “A vast underwater network of cables crisscrossing the ocean makes it possible to share, search, send and receive information around the world at the speed of light.” These cables are made of optical fibre.

Detailed explanation-2: -Modern submarine cables use fiber-optic technology. Lasers on one end fire at extremely rapid rates down thin glass fibers to receptors at the other end of the cable.

Detailed explanation-3: -The cables are laid using ships that are modified specifically for this purpose, transporting and slowly laying the ‘wet plant’ infrastructure on the seabed. These special ships can carry thousands of kilometers of optical cable out to sea.

Detailed explanation-4: -Today, there are around 380 underwater cables in operation around the world, spanning a length of over 1.2 million kilometers (745, 645 miles). Underwater cables are the invisible force driving the modern internet, with many in recent years being funded by internet giants such as Facebook, Google, Microsoft and Amazon.

Detailed explanation-5: -At its most simplistic, data sent over a cable is converted into binary code – a collection of 1s and 0s. The device transmitting the data will send current along the cable at two different voltages (for instance, 0V and 5V), with one voltage representing 1s and the other 0s.
