Clearly explain how internet works along with introduction all notes?

The internet is a global network of interconnected computers that communicate with each other using a standardized set of protocols. These protocols allow computers to send and receive data packets, which are small units of information, across the network.

When you access the internet, your device, such as a computer or smartphone, connects to your Internet Service Provider (ISP) through a modem or router. The ISP then connects your device to the larger network of computers that make up the internet.

Once connected, your device can send requests for information, such as loading a webpage or sending an email, to other computers on the internet. These requests are broken down into data packets, which are then routed through a series of interconnected servers and routers to reach their destination.

At the destination, the data packets are reassembled into the original request, and the requested information is sent back to your device in the same way. This process happens in a matter of milliseconds, allowing for near-instantaneous communication and data transfer across the internet.

In conclusion, the internet works by connecting devices to a global network of computers through standardized protocols, allowing for the seamless exchange of information and data packets between users around the world.
