Ethernet Switch- what's the point?

@zavato 

Apologies for the bickering.

Freddy22, panzerwaggin, cakhole, and others (12 many joins) continually try to ruin open discussions by spouting their 'networking' knowledge. Side with them at your peril.

The winners in this? Those who have researched, discussed, and tried network switches; made their mind up from there.

I have two. Well worthwhile in my system.

Puzzling, maybe for you.

But I would without hesitation join nonoise for a cup of tea.

You just pass on by. 

Or perhaps just shove off?

I read recently in these instances a long run of optical cable using an ethernet media converter at each end ensures no unwanted noise inserted along the length.
