Ethernet Switch- what's the point?

I run an Ethernet cable between my router (standard issue from Verizon) and my streaming transport. I note that some use an ethernet switch between between the router and streamer. Assuming I got that right, what is the point- what does a good switch do? I've been into audio since the 70's but when its comes to streaming, I'm definitely a newbie- 

Thanks all!

@yoyoyaya Well, Occam's razor applies. If there is not way a switch can improve anything, which is a fact and how Ethernet and TCP/IP is designed, guess what is the next option?

And before you say you don't understand pcaps, yeah, that is the whole point. So stop lying.

Why do I call it lying? Because you have been told over and over again what the reality is, and you continue deliberately, willfully and intentionally spew the same garbage.

@fredrik222 Occam's razor doesn't cut it when one relies on argument from authority fallacies to make one's case.
