+----------------+ +----------------+This diagram shows the internet as a big network made by connecting smaller networks.
Each box represents a smaller network: Home, School, Business, and a Data Center.
Inside each smaller network are computers or servers connected together.
The lines show how these smaller networks connect to the internet, which acts like a big hub connecting all of them.
This is why the internet is called a "network of networks" -- many smaller networks join to form one huge network.
