This is my 1st post After Introducing. Guys, You Know We can Live For a day Without Drinking water and can live Without eating the meal for a day But we can not live without internet for a single day.
Guys have you ever thought how this Internet work in the country and how this internet reach to us and how some people get more speed and how some time people get slow internet and you know why country gives different plans on a different price and have you know who is the owner of the internet.
As you know all the world connected by internet but how it is possible and how it is manage if you think it is work by satellite it is completely wrong.You may Don't Know 99% network running by optical fiber cable.
Maybe You think that I use mobile for internet but your mobile get the signal from the tower and all mobile tower are connected to each other through the cable. internet passes three layers before reach to you that is...
Tier-1
Tier-2
Tier-3

Now we will discuss this three layer. There is all internet (optical fiber cable)placed in the sea, this cable connects one country to other and connects whole world by this cable to each other.The companies placed this cable in the sea called Tier-1.
After the Tier-1 company here this internet divided into the different states of a country and this work done by Tier-2 company and this company pay amount on the basis of per GB to Tier-1 company.
Now after states, this is divided in the different cities of the state this is done by the local company and the Vendor this local company called Tier-3 and this pay more amount to the Tier-2 company on the basis of per GB and this all amount collected from us for providing the internet service.
Now we will discuss how this places in the sea from one country to another.
In this large cable, you can see every cable's size like your hair and every cable has 100GBps speed.many companies placed this cable in the sea. These are called Tier -1 companies.Every country has its landing point where this cable come out from the sea and many companies placed the tower.
If you search anything which is located out of the country then this will be passed through this landing point and reach to the server.
The age of these cables is approximately 25 years, after which they must be replaced, to avoid any sudden failure.
The world will be disappointed if the internet went down even for a second you know.

For example in India you can see in the graph it vary on the basis of time it showing continuously down after 12:00 to 6:00 because this is sleeping time in India so very few people use the internet and after 6:00 AM it is raising because people start their work here data use continuously in the daytime.
in the image above you can see the various landing points across the continents. and the red lines represent the laid out cables, and the path they follow in the Indian Ocean. most of the data and the messages we send are transferred either via submerged cables or satellites.
But almost all the Internet is connected via the submerged cables.
There's a lot riding on these cables.
