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!

Jeff / Earl: my apologies. Not sure who controls the Audiogon posting today, but I thought I’d apologize. You and I are in the same “camp” most of the time (other than The Orange related stuff). But you keep attacking me for some unexplained unexpected reason, whatever that is.

Just ignore the likes of Freddy….it’s best not to engage them. I am glad to hear you’re loving the Muon Pro. 

@thyname first off I am not Earl, Jeff or any other name in your head. You also need to get a sense of humor the joke was Freddy is the bear. I will never address you ever again. The EJDS runs deep in you.
