Source of internet ?

The whole world uses internet .we download data ,we upload data ,we stream youtube videos and song directly on our devices but from where this data is coming from? Where is the whole internet's data stored?

The information on the Internet is stored on the hard drives of web servers all over the world. Web servers are, at heart, ordinary computers just like yours.

Servers are often organized into vast networking hubs, buildings filled with numerous racks of computers. These racks are often connected to each other as well as the Internet, so they can exchange, process, and store more data. These databases store an obscene amount of data, thousands of encyclopedias worth, easily. To summarize, information present on the Internet is stored where the server for that particular website’s or application’s server is located. In order to access data not stored on a personal computer, web browsers are needed.
