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!

@zavato   Proceed with caution - there is a lot of wrong info in this thread.

@carlsbad2 You don't understand the technology.

@fredrik222 I admire your perseverance, but you will never change their positions.  No reason to continue.  It reminds me of my grandmother.  No amount of kind explaining or reputable news articles was enough to convince her that a microwave was not putting nuclear radiation in her food.  

I hope you all have a great weekend. My second Rythmik F12 is arriving today and I can't wait.  It is going to be a wonderful and loud weekend.  

@12many Indeed! The clarity of the information I’m getting was reminiscent of the New York sky earlier this week- obscured!   Enjoy the new sub!! 
 

@12many i know, that is not the point, the point is to counter all these people are telling people to spends thousands on dollars on things that doesn’t work. So hopefully people don’t go wasting their money. 

@yoyoyaya and we are back to bias.

the facts of how a switch works doesn’t change. It is not an intelligent device that can make decisions based on what is transported via the switch.
