Looking for network architectures

Hi everyone,

We have a school research project in which we need to create network architecture diagrams and explain the reasoning behind constructing the network that particular way.

Now, we are quite short of accessible network architectures to work with, so we'd like to request some help. We will build the diagrams and write fancy-text (so we're not asking you to complete our problems in the slightest!), we would only like to hear about a network architecture's basic structure that you know of, manage or own.

We need information such as:

1. What devices are on your network

2. What others are they connected to or can be connected to (eg. wifi routers)

3. A fun fact of a device, why is it in the network that way (your choice)

Thank you for your time.
