Is the Internet comes from satellites?
No, the Internet cannot come from the Satelite. I know You are thinking “Why??”. So, you are right currently it’s not possible but in the future, It will possible. So, Why Currently it not possible. Friend, We know satellites are too far from earth land. We all use the Internet on Land. But Satellites transmit data in half-duplex mode. So, in Simple Words Satellites can only Send or Recieve data at a time. But, on the internet, we Require to Send or Recieve both at the same time or we can say it require Full duplex Process.
We will Know it in deep in our future posts.
Who is the Owner of the Internet?
Actually Friend Internet has no particular Owner. Whoever Use the Internet is the Owner of the Internet. So, here are three types of Companies. Which maintains the Internet but not the owner of the internet.
So, these are : Tier 1, Tier 2 , Tier 3 Companies
Tier 1 Companies
Friend this company Connects country to country or continent to continent via using Submarine Cable. Friend, in Simple words data transmission between country to country or continent to continent is possible because of Tier 1 Company. These Companies are Responsible for Maintainance and new Submarine Cable Installations even they have responsibility for backup links. If in case any link damage through any shark or any other reason. Well, they Create a backbone network of the internet. Tier 1 companies have an agreement with Tier 2 companies.
