How it really looks on the Internet
Source:The Internet today can be called one of the most important resources. For us it is so affordable that it seems as if he is omnipresent. Our smartphones and tablets get it without any wires. In fact, technology works far more primitive, and the concept of the Internet is embedded large-scale and very costly network. We will tell you all about it.
How it works
Speaking in plain language, the Internet transmits information from point A to point B. These points are the IP addresses – the unique codes that identificeret location of devices around the world. But any information goes through the data servers, which are located in the centers. On the map below you can see the location of all such centers.
theAs information passes between data centers
The Most simple, fast, reliable and affordable method of information transmission is the cable. The Internet is almost completely relies on cables. The problem is that many of these cables pass through the reservoirs. It makes your hair very long, costly and complicated. This process took almost 200 years.
Today there are over 300 with a total length of almost 900 thousand kilometers. 97% of all Intercontinental data transmitted through these cables, and if you put them one to one, it will be possible to reach them from Earth to the moon and another three to wrap around the Earth.
The length of the longest submarine cable at almost 40 thousand kilometers. It runs from Germany to South Australia. And the first transcontinental cable is laid from Ireland to Newfoundland in 1858.
How to lay and maintain submarine cables
Laid Under water cables of different types. The most subtle of them thick with a garden hose. The basis of all fiber optic cables are wires that are protected by a layer of stranded metal and moisture-proof layer. Laying of this cable requires several months of work, millions of dollars and a huge vessel on which the cable is minimized.
According to MIT Tech Review occur annually at least 50 breaks in submarine cables. They are repaired by divers or by means of special vessels, which tightens the two ends of the cable in order to carry out repair work on Board.
thethe Underground
From the water, the cables go underground. Under the ground they go to centers. To reach and maintain cables under the ground easier, but still not too easy. Usually they go along the roads, and gas lines or water pipes. They come in data centers that consume as much energy as is consumed for 3,000 homes.
Each center is equipped with a huge number of racks with servers and fans that operate deafening loud. The security level of such centers is higher than at some airports. It is from them we get the Internet through the same cables. This cable can be routed to your home, and can reach the tower operator.
