You made me stop and question myself for a second, but this definitely isn't right. Usually when people talk about "TCP/IP" it's shorthand for the whole "Internet Protocol Suite", but even naively TCP and IP are two different layers.

Yep, the slash is meaningful. I think of writing "TCP/IP" that way as in a fraction -- "TCP over IP" or "TCP on IP". At least, that was how my brain learned it.
