Internet

It is a group of network that communicate with each other in order to share data between them. They are interconnected with each other via physical cables. They are laid across the globe.

How does internet work ?

User must have an ip address in order to exist in a network.
Users pay ISP to get access to data across the globe. When a user requests for a data, it sends request to isp and the isp will redirect to the data centers.

ISP

ISP - Internet Service Provider
They are the provider of internet. They provide access to the internet via which people share data and request for data.

Note :Many people think that internet is something they provide, no!!. They only provide access to the internet. We people use ISP as a medium to access the data across the globe.

Submarine Cables:

Data from the servers are accessed by the people in the world using submarine cables. These cables are laid between different countries. Visit https://www.submarinecablemap.com to have a detailed view of the cables laid.
They are well protected from getting damaged, consisting of many layers of protection.

Flow of data:

ISP : Act as medium
User : Access the data

1. User don't have access to the data in the server until they have an IP.
2. In order to access the data from the server the user pays the ISP to access the data.
3. The ISP provide the data in return, to the user.

ISP's provide a specific amount of data to be transferred
For example, 1gb internet package means we can send or receive data of 1gb.
