Need help in networking fast please !

[Moudi]

I have a homework for tomorrow,

We studied that the router can seperate two networks, but we have a homework for today that looks like this



computer --->[switch]---->[Router]----->[Router]----->switch---->computer

So basically we have two kinds of networks but what i want to know, is the bolded part considered a network ?
Like does the router n1 consider router n2 a node ?

Please help me and briefly explain..

these are two distinct networks connected via WAN [Router]----->[Router]
