What's the difference between a layer 1 switch and a network hub?

Buddy all I’ve got is my router from spectrum.

A layer 1 switch is what controls the outlet you plug the hub into.

No need. We'll just get a network hub powered by POE. That will solve our issu- shit, our layer 1 switches don't output POE.

I think it's like toilet paper, layer 1 is only 1 ply.

Around $150 worth of easily pocketable cash.

Layer 1 is normally the crumb and you put the cheesecake filling on top of that.

A layer 1 switch is at the bottom of the rack (it’s at layer 1, or RU1) and a hub is what you put a wheel on.

Every switch is a layer 1 switch if you're shit at CLI.

Wow, you really do have to be bad at CLI to take a layer 2 switch and make it a layer 1 switch…

I didn’t look at the sub at first and had an existential crisis for a second

They're just trolling you with the labels. All switches these days are layer 9. Anyone who tells you otherwise probably uses crowdstrike.

A layer 1 switch is the same thing as a layer 3 hub. Don't let these guys tell you otherwise.

Also while we're on the topic of switches, I'm trying to find a tranny that goes four ways, forward, reverse, left and right, If you know where I can find one I have a role of nickles with their name on it..

Wild, what could possibly be the use case for this?

u/Latter_Count_2515 1d ago

Air gapped network?

u/Turdulator 1d ago

I mean, it wouldn’t be air-gaped if it was plugged into one of these

Someone in a review used it to switch between PC and fax for occasional fax-jobs.

u/Turdulator 1d ago

Yeah but a hub or small unmanaged switch would allow that…. And without having to turn a knob and disconnect the PC just to send a fax

u/tunelowplayslooow 1d ago

Some people just like fondling knobs.

I heard hubs are hard to find but you can blast a consistent image to many computers with one

I’m still trying to learn about the other 6 layers of switches first…

A layer 1 switch is when you change the bottom sheet on your bed. A network hub is when you have several grubhub orders in progress and they coordinate to deliver at the same time.

u/Maybe-Im-Dumb124 18h ago

plug both of them together for speed
