Ethernet hubs versus switches

A simple demonstration of the difference between an Ethernet hub and an Ethernet switch, and how this can get you into (temporary) trouble if you’re not aware of how a switch works.

I actually learned something. thank you a lot!

Angry Dergon says:

so which is better to connect an xbox and 2 computers to the internet with?

Zafren Zainudin says:

thank you!!!

Tom Chopper says:

I appreciate the “plain English” explanation!


thanks for sharing, that was helpful.

Stikky says:

Too advanced what the fuck is the difference

Ted Smith says:

That was an incredibly good explanation. Thanks!

Gary Walker says:

Too much jargon and alphabet soup for a novice like me.

Aj Caballero says:

Hey, i really wanna know more about this switch thingy (i’m new so don’t hate) uhm, i need further explanation on how it works. if you use the desktop1 (port 2) will it affect the performance of internet in desktop2 (port 3)?

Pierre Cardone says:

thank you. this is the clearest explanation of the differences between a switch and a hub that I have ever seen.

vsajewel says:

Wow! Great explanation and demo…I never knew we had to reboot the switch! Thanks so much!

W1llums says:

Absolutely stellar video. I very rarely see such clear and concise tutorial videos for networking features. And the fact that it used a PLC and an HMI, as opposed to just a router and a PC like most videos on this make it excellent.

Michael Christian Groves says:

Very helpful. Thanks for sharing this information. I

Hermis Gonzalez says:

Thanks man for making this video. I learned a great deal by seen this.

frank2398 says:

That’s the problem with a $49 Staples switch.

Lynn Thompson says:

Thank you! You are an amazing teacher. That was so clear, it was a pleasure to watch!

M.r. performance Fast wrx says:

Ok say i only have one cable modom no router and have 1 laptop and 2 ps4 what do i do ? Anything for this problem beside a router

Dracolith1 says:

Forgot the most important difference…. Switches make Full-Duplex connections, and Hubs make Half-Duplex connections. That means a device cannot receive while transmitting on a Hub, so there’s at least twice as much bandwidth with a Switch.

Readme .txt says:

Switches are intelligent devices, and the behavior is programmed intentionally. I have tried simmilar test, using Windows PCs, but the delay problem had not occured.

terry waller says:

If you have a large network and/or are concerned with speed you need a programmable switch so you can control your routing, and set priority.

Brad Guenther says:

can this connect 2 signals at once at gb speed expample desktop and laptop?

V. Z. says:

Lastly. I want to add a projector to my living room. I have an existing Ethernet going to my Roku device, all the way from my router in another room. I want to plug the existing that existing Ethernet cable to a switch or hub, thus removing the Roku as the one and only terminating route, and then plug my Roku and projector into that switch or hub in the living room. For something so mundane, would you recommend a hub or switch for this network solution? And why? Thanks!

q zorn says:

great info, automationdirect needs to have this video. thanks.

V. Z. says:

3:28 It seems that the way it’s explained, the hub and switch are doing the same thing. He explains the Switch is sending messages to a specific MAC? It’s unclear. I’m only beginning to research switches and hubs though my understanding of CS is far wider than my specific understanding of networking. So, is this Rather Desktop Unmanaged vs Desktop Web Managed? I’m asking, not stating, because I really don’t know. Thanks.

Pebber Brown says:

PLC? QUERY? HMI? A tech guy talking to an audience of assumed tech guys.

Raymond Copeland says:

Ok you see where it’s said the switch can work out the MAC address and transfer data to its own cable and not across all ports like the hub what happens on a router dose that act like a switch or dose that too send all data across the ports ?

Eugen_int64 says:

Studied information science and had to stumble upon this to finally get enlightened! Thanks!!!

Aboubakar Bappah Aliyu says:

That’s Amazing

john doe says:

great explanation and easy to understand

joshua kosmela says:

Great video. Thank you! Explained exactly what I was wanting to know!

KL says:

thanks. didint’ realize this was a problem. have had it to me before in my small office

Sjrick says:

ok i just bought a 24 port switch. Does it matter which port i use to plug the main feed
into from my home modem ?

V. Z. says:

3:54 Can this be cleared via unplugging and plugging or cycling the switch? (edit: 30 seconds later my question answers itself in the video, great coverage!) This makes sense though, does this also happen with household routers? I’ve often pondered this notion when changing slots while troubleshooting. Or even USB ports would this happen? I ask about USB ports because sometimes when troubleshooting a plug and play (pray) solution the drivers won’t load and I have to reboot to see the “cannot find drivers online” message a second time because it will only alert once. Thanks.

Jimmy S says:

If you mixed 100Mbps gear with 10Mbps gear on a 100Mbps Hub the hub will only operate at 10Mbps even on 100Mbps hardware on other ports. A single 10mbps network card will drag the speed down of all 100mbps devices to 10mbps on any hub.

The switch will have no trouble with connecting 10mbps 100mbps and 1000mbps/1Gbps hardware together at their max rated speeds when using at least cat5e wiring or better. . So resetting the switch to reset the mac address table is less of a issue when it comes to speed.

Sovereign Rebellion says:

Does this work to multiple your connections, say you want to turn one Ethernet cable into ten?

U K Somerville says:

PLC, HMI acronyms not explained.

KELLI2L2 says:

Such LOW volume, can’t hear you in quiet surroundings…

Richard Wilson says:

Nice clear video. Thanks.

Miguel Angel says:

Whats the model of t he Netgear switch ?

kracksmith4ejm1 says:

Correct me if I’m wrong but when you moved the PLC blue cable from port 3 to port 4 and it don’t communicate is because the switch will look at the source MAC address on it’s MAC address table for that known source MAC address. If that source MAC address is on the switch MAC address table but was on port 3, the switch needs to wait 300 seconds (5 minutes) for the switch MAC address table to expire before it can log that same source MAC address to port 4.

Steve Packard says:

Do they even still make hubs?

KushFriendlyXeX says:

I got a 8 port switch and a 5 port switch both by netgear and they work great.. mine are both gigabit tho

BigAmbience says:

What a clear and well explained video. I learn’t switch behaviours I didn’t know, thank you

FrostyNugg3ts says:

Is the resetting of the ports when the slave is changed dependent on the switch model with regards to the timeout? ie. 5 minutes for this particular Netgear. Can this timeout be adjusted in the switch settings?

Mum Blic says:

A switch can pick up is new connection (almost) as fast as a hub. It all depends of device configuration
The only real difference between a hub and a (unmanaged) switch is collision avoidance.
