Understanding Computer Networks by Analogy

I'm writing a series of post to help me and help some of my friends to understand a little bit better computer networks by using analogies.

I'm going to start with Networks, subnets and devices but I want to expand to more topic like switches, routers, internet, SDN, etc.

What do you think? Do you have any feedback?
