I have been researching on what the difference is between Routers and modems but didn't really understand until I saw your video. The visual aids and how you explained it, made it so easy to understand that I felt rather stupid. LOL! But part of the confusion is how common it is for one device to have the functionality of many others. For example, I would have never made the distinction between the Router, and the switch ports built in. The visual aids along with the explanation made it so easy to understand the actual purpose of the individual ports and the purpose of a device. Thank You so much for taking the time to share the knowledge you have.
Thanks for this man! Would love a similar video explaining the connections/differences between routers, switches, access points, and servers. You have an amazing way of explaining.
Not even a minute in and I said thank you so much! I'm going to start studying for my cisco networking certification and I have a loooong way to go. I have zero based knowledge, so yes, people like me need to know the difference between the router and a switch. Thank you!
So if I have a small home network with 3 devices, there's no point in a switch besides if I want to expand it later on? The router is as efficient at routing the internal network traffic?
You're brilliant and I'm subscribed, thank you. I'm taking a networking course and it's difficult to understand the difference between all these devices that do similar but not *quite* the same things.
The switch doesn't "know" anything about internet or IP addresses. Its job is to send/receive data frames. It only understands MAC addresses. Let's say you have 2 PCs and a router connected to the switch. When PC-1 wants to go to RUclips (for instance), PC-1 will first try to figure out if the youtube server is on its network. Since it isn't, the PC sends the request to the router. Your PC knows your router's MAC address. In the frame, PC-1 puts its MAC address as the source address and your router's MAC address as the destination address. When the switch receives this frame, it looks at this data. It has something known as a CAM table where it maps what MAC address is associated with what switch port. In this example, the switch knows that the MAC address for the router is on port 1. The switch then sends that frame to port 1 where the router receives it and in turn, routes it to the next router until it gets to the destination. This is more or less the technical explanation of what's happening. Switches operate at layer 2 of the OSI model where they work with data frames and MAC addresses. They have no concept of IP addresses.
One internet connection to the outside world usually only needs one router. But probably lots of switches. If you really have something that large then you should either have an IT person on staff or being working with an IT consultant. 😊
Sorry I'm still confused. What if I connect the switch directly to the internet. Have I not multiplied the number of ports? Have I not provided a way for a PC, printer, Laptop, to all get internet and talk to each other, ie send a print job from PC via the switch to a printer.
From my understanding of the video, the main issue with your proposal is there does not exist something to convert "LAN language" to "WAN (internet) language"
So how would the router know the individual Private IP addresses of each device connected to the switch 🤔 does the router just go off MAC addresses and it doesn't matter? Or does the switch somehow keep them separate as well?
Great observation James. Me thinks you know a little more here than what you are asking. 😉 The router maintains a mini database of which MAC has which private IP. The switch may, it may not, maintain a list as well depending on how smart it is. And, there is some additional Network Address Translation magic going on to map Internet responses back to the appropriate requesting host. Great question! 😁
Is that a Modem/Router combo? I thought it was the Modem that connects to the ISP directly, to convert appropriate signals. And then you hook up a router to the modem.
Hi, whats the point of having a patch panel? Cant we just conect direct to switch? Why do we have to conect to a patch panel than we have to conect from patch panel to a switch?
Great question! Functionally, yes you can skip the patch panel. But when you dealing with, say 10 or more, network outlet locations, having a patch panel really helps keep things straight. It s a best practice in the industry. And, when you get into commercial settings where one network closet might have 200+ network cables, there’s no way you could efficiently manage the connections without patch panels. 😊
which solution is better; computer connection to router or switch? where will i get lower ping? Will I see all devices connected to the switch after logging into the router?
Tnx for this...I wonder what should I buy when I wired my internet using fiber optic wire to another 300m distance...in my base station I used hex mikrotik din to media converter A to another point using foc then tap to media converter B then to SWITCH to distribute my client...
The only video I've found that's made this make any sense. So the 4 ports coming out of the Router is a Small Switch. Meaning that if there was only One output port or LAN then it would Only be a router or in other terms a Gateway. Right?
It's getting blurry to be sure. In fact, at the enterprise level, high end switches can Evan function like routers (to a point). Lately, most consumer-grade routers I've seen come with those 4 built-in switch ports.
@@danna7838 I'd also like to add that if you connect your PC to the modem, your PC will get a public IP address and will be exposed directly to the Internet. So unless you have good security on your PC and it is updated, I wouldn't really recommend doing this.
@@NetworkAdvisor "only one computer will get the address to access the internet" => which one will that be? In a 16 port switch, if port1 has an incoming connection from a modem directly (instead of going through a router) and ports 2-16 are connected to PCs, which one of the 15 PCs will "get the address to access the internet"? Similarly, what would happen if port1 had an incoming WAN connection directly (without a modem or a router)?
Great explanation, thank you! If I want to have 2 separate networks, one for home (already set up) and add a new one for work. Can I split the ethernet cable from the Modem into 2 separate routers?
No. That won't work. Most modems only have 1 ethernet port so you cannot plug in 2 routers. What you can do is to create a VLAN. This is basically a virtual network. You can have a VLAN for your home network and a VLAN for work. You can create firewall rules so that neither your home network devices and work devices can talk to each other or see each other. They will be running on the same router, but will logically appear as 2 different networks that have no idea of each other's presence. This is a more advanced setup that is not typically seen on most home networks. Depending on the router you have, it may or may not be possible to do this.
Thanks for the informative video. Question, can I install ExpressVPN to the LAN switch instead of the router? All I'm seeing when I do a google/youtube search is how to install ExpressVPN on routers not sure if they apply to switches. My plan is to connect 2 switches to my router but install ExpressVPN on just one of the two switches.
Hi Steve, what do you think of using strictly isp router modem combos? Do you recommend using an external router with those devices for security reasons? Also what are good residential routers that have lots of features like ssh or vpn features? There seems to be not very good options in the big box stores for those features.
I've done both. When you have your own router (not provided by the ISP - cable company or telco), you have a lot more power to shape the behavior on your LAN. And, your'e definitely right about the security aspect. I have to admit, I've done both. Mostly because of laziness, I've used the Cable company provided switch/router combo unit. As for what is a good SOHO router to get today? Hmm... The Cisco RV series is pretty good and not too expensive. Unlike the big Cisco routers, you don't have to program it from scratch by Command Line - it comes with browser-based config menus. I used an RV042 for years and it worked great. They have better ones though and rich with features like VPN, dual WAN, and K9 security (woof!) :-P Overall, It's a really great question, Jonathan. And, I'm probably not the best one to ask. Maybe I'll post it on my FB page and see what others have to say. Thanks for bringing it up! :-D
exactly Wolf. With a dumb switch I wouldn’t do that. however, smart switches (i.e. Cisco, Juniper) might have that capability. But even then, it would have to be configured. great question though!
Is it possible to connect a Nas and a pc directly to the router and some other computers and network printers to the switch (which is connected to the router) ? Do you think it could work ?
what i don't understand is why a switch is needed then? why wouldn't humanity just sell routers with more ports? and why have i read something along the lines of "a switch allows you to create multiple LANS, but under one router?" is that right? can you connect a router to a switch and have 2 static IP addresses from the ISP?
So your assertions are correct in a more complex environment. The target audience for this video is small office and home users. In the enterprise level arena, routers and switches are much more complex and capable. For one thing, enterprise-grade routers don’t usually come with four built in switch ports on the back (thats just something the consumer-grade routers have for convenience). Typically there is only one (maybe two) gig Ethernet LAN ports. Also, industrial switches are not dumb (as most soho type switches are). The switches used in larger offices are “layer 3” capable. Which means they can be divided up into separate VLANs and make routing decisions on their own. So, those are great questions. It’s just not in the scope of what I was trying to explain here. Thanks for watching! 😊
Jon, totally agree. One tell-tale sing of a Router is when you see a port marked "WAN" (wide area network). most consumer-grade switches don't connect directly to a WAN. thanks for commenting.
Edwin, I may not be totally understanding your question. You can put a router behind a router (not recommended). But, Unless you are very sophisticated I would not connect two routers to the same switch on the LAN side. It will confused your host machines.
@@NetworkAdvisor First, thanks for your reply. Right now my ISP provided router is connected to another router (located in another room in our house) and it's working fine as far as using that second router for wifi purposes. I ask the question because our ISP provided router's 2nd 3rd and 4th lan are not activated only the 1st. So therefore I cannot use the 1st lan for my laptop because it is connected to another router like I said. That's why I was thinking when I saw your video that perhaps if I use a switch then I can connect now both to my laptop and 2nd router. FYI, the setup right now is this: From ISP provided router I use LAN 1 to connect to another router using its Internet port (WLAN is it?) and not LAN port. And it works. Thanks again.
Thanks for subscribing! Glad you thought the message was clear. It's always been my goal to take the obfuscating language out of tech concepts that really aren't that complicated after all. 😁
So, can I run 4 cables to 4 different rooms in my house then, put a switch in each room and have multiple network points in each room. Sorry for the noob question but I'm in the UK and the house is solid brick between each room. The less cable run is a bonus.
That is completely correct. This is frequently done in commercial environments. You *might* see a little bit of performance degradation in that topology. But, better quality switches and router would help prevent that (I don't mean you need to spend thousands of USD, Just not the cheap stuff). Good luck with that! :-)
Well, I suppose you could argue that case. Especially as MIMO WiFi technology is getting better everyday. But; most IT pros would prefer a hard wired Ethernet connection to a switch. Great point! 👍
What you are referring to is known as “trunking”. Most consumer-grade routers/switches do not support it. You can try connecting two cable between your router and switch, but I think the router will only recognize one path. Excellent question! 😄
@@NetworkAdvisor Thank you for the reply. In a switch specification, it is written Data Rate: 10/100/1000 Mbps at Half Duplex 20/200/2000 Mbps at Full Duplex I do not get that. How can a Gigabit switch transfer data at 2000Mbps at Full Duplex? Switch specification: www.mercusys.com/en/product/details/ms105g#specifications
so, that's a really great questions. In a simple dumb switch, the answer would be NO. However, in more sophisticated switches you can do almost all the functions of a router (ie. defining the DHCP scope for IP addresses).
I have a expert question in this topic: Say you have a POE Switch for your poe Security cameras - one Cat 6 cable, no adapter needed, Plug in cable Into camera and Switch and all floorlessly ok. Now say you get a POE Doorbell cam (from company yoosee). Why doesn't it Work at all the same way? Device comes with RJ45 adapter cable - meaning you shall connect your Ethernet cable - No Matter how good- to the Doorbell and the other end of the cable to some sort of RJ45 adapter cable that splits Into 2 Ports. One end of that adapter has another RJ45 (that you shall Plug in a Router) and the other Into DC Adapter. Now i dont have a Router. Only the Poe Switch for the cameras that has No wifi. Is it worth purchasing a router Just for the doorbell? And how can i use it, if the only ethernet Port of my Modem is used by my non WiFi capable Poe Switch for the cameras?
Okay so I'm a total network noob and I know this is a very rudimentary question, but what would happen if you were to take that connection from the modem and plug it into the switch directly?
Great Question Utkarsh! It seems as though that would be such an obvious way to set it up. However, the switch (most consumer-level switches) are not doing layer-3 routing. Put in simpler terms: The switch is not smart enough to know how to make the routing decisions between the PC's on the local network and the Internet. This is the value the router brings to the process. :-)
The issue I’m having is that my router from my provider is on the other side of my man cave and I want to have all my game systems and both PCs plug Ethernet i have only 1 cable from my router to the man caved for my game rig can I use that 1 port to a switch so I can multiple ethernets without haveing a crazy mess of 75 feet cables from across the room is that possible I’m realllly new to this lol
@@secretbeach999 I have (had) a few. I had a CCNA once upon a time. I've not renewed it. The CCNA cert is a good buck/bang ratio in terms of getting your foot in the door.

Network Advisor thank you! That's great advice. I'm studying for my CCNA right now. I plan to learn some Linux along the way, along with some Python and then eventually into security =]
Hi, says so on the wikipedia. Cisco Systems owned them until 2013 apparently, not 100% sure though. I'll take this opportunity to thank you for all of your videos! I couldn't recall myself,
I've got an IPS Modem, that has Both Wifi and Lan connection. I run one cable towards a Router that also has Wifi and Lan ports. Now I'm gonna Swap the Router with an Switch so I only have to Port forward the IPS Modem and not both the modem and router. The IPS Modem is on the Ground floor that connects the Router on the 2nd floor Attic and the router connected to my PC. Or i could just buy an 40M UTP Cable instead of the 2 20M I've got.
Thanks for for the clarification. One question: Are all the cables you're using "ethernet" cables? Are certain cables different colors? I've seen ethernet cables typically being yellow and blue.
Thanks for the video. It seems that anyone connected directly to the router would get much faster service than those who are sharing the router port via a switch. Is this observation correct?
Genreally not, unless the switch is part of a router/swtich/wifi combo. To add Wifi to a network, a device called an "Wireless Access Point" is connected to the switch. Great question, thanks for bringing that up!
Dear, can you please show us the route of fiber optic cable from OLT to ODF (inside data center) to Optical Splice Closure (inside Manhole) up to user's location?
Very simple and wrong. Switch isn't dumb, that would be a hub. Switch builds it's own mac tables to route packages to apropriate receiver. It can even have ip routing tables. Router on the other hand is a switch that does ip routing, address translation, dhcp and dns server and physical firewall. Also almost all of them have wifis these days. They also have web interface for management and much more. Main benefit of a switch is that you get way more ports for same price and possibly lower latency.

Can we connect modem to swich then to router (i need this for some reason)
You could. But any computer or IP device needing the Routing services would still need to be connected to the router via another switch.
@@NetworkAdvisor routing service means?
Roiting service means.. Isp service provider username and password? Please make it clear
Nicely explained. So switch cannot be connected directly to modem. Right
Generally, no. Switches wouldn’t be connected directly to the modem. 😊
Thanks, simple and straight to point. Thanks again.
Thanks to you Saul Goodman for all those informations
So, can I run 4 cables to 4 different rooms in my house then, put a switch in each room and have multiple network points in each room.
Sorry for the noob question but I'm in the UK and the house is solid brick between each room. The less cable run is a bonus.
That is completely correct. This is frequently done in commercial environments. You *might* see a little bit of performance degradation in that topology. But, better quality switches and router would help prevent that (I don't mean you need to spend thousands of USD, Just not the cheap stuff).
Good luck with that! :-)
Q. Does wifi make switching outdated since you reach multiple computers?
Well, I suppose you could argue that case. Especially as MIMO WiFi technology is getting better everyday. But; most IT pros would prefer a hard wired Ethernet connection to a switch. Great point! 👍
Hi,
can I connect two cables between a ROUTER & a SWITCH?
What you are referring to is known as “trunking”. Most consumer-grade routers/switches do not support it. You can try connecting two cable between your router and switch, but I think the router will only recognize one path. Excellent question! 😄
@@NetworkAdvisor Thank you for the reply.
In a switch specification, it is written
Data Rate:
10/100/1000 Mbps at Half Duplex
20/200/2000 Mbps at Full Duplex
I do not get that. How can a Gigabit switch transfer data at 2000Mbps at Full Duplex?
Switch specification: www.mercusys.com/en/product/details/ms105g#specifications
I've been trying to learn the difference and this video finally made it click
lot's of video the whole day then i saw this...got it! : )
That’s wonderful 😄
How about the assigning of ip addresses? Can a switch do that?
so, that's a really great questions. In a simple dumb switch, the answer would be NO. However, in more sophisticated switches you can do almost all the functions of a router (ie. defining the DHCP scope for IP addresses).
Thank you for this! It really helped me!
Aaaaand you got yourself a subscriber!!! Thanks man, good job.
that's great. Thanks for watching! :-)
Amazing explanation, thanks!
Excellent clear description thank you so very much
Is this low FPS or stop motion??
Really? Its that bad? I think I used a Pixel 2 to shoot that. Probably the default settings.
Network Advisor it’s fine
I understood everything
Great video
But it really looks like stop motion lol
Wonderful video! Simple explanation! Thank you!
Thank you for sharing your feedback. 😊
What happens if you take the connection from a modem and plug it into a switch instead of a router?
Jonathan, you can do that, but usually only one PC will be able to access the internet at a time.
pls your vides are perfect and straight on point.
Thank you sir. And, thanks for watching. 😊
I have a expert question in this topic:
Say you have a POE Switch for your poe Security cameras - one Cat 6 cable, no adapter needed, Plug in cable Into camera and Switch and all floorlessly ok.
Now say you get a POE Doorbell cam (from company yoosee). Why doesn't it Work at all the same way?
Device comes with RJ45 adapter cable - meaning you shall connect your Ethernet cable - No Matter how good- to the Doorbell and the other end of the cable to some sort of RJ45 adapter cable that splits Into 2 Ports.
One end of that adapter has another RJ45 (that you shall Plug in a Router) and the other Into DC Adapter.
Now i dont have a Router. Only the Poe Switch for the cameras that has No wifi. Is it worth purchasing a router Just for the doorbell? And how can i use it, if the only ethernet Port of my Modem is used by my non WiFi capable Poe Switch for the cameras?
Very nice understandable difference, appreciate your good effort.
Okay so I'm a total network noob and I know this is a very rudimentary question, but what would happen if you were to take that connection from the modem and plug it into the switch directly?
Great Question Utkarsh! It seems as though that would be such an obvious way to set it up. However, the switch (most consumer-level switches) are not doing layer-3 routing. Put in simpler terms: The switch is not smart enough to know how to make the routing decisions between the PC's on the local network and the Internet. This is the value the router brings to the process. :-)
@@NetworkAdvisor I had the exact same question. Thanks for your answer.
Thanks! Really helped a definitely non-pro like me, peace.
Wonderful video very easy to understand
The issue I’m having is that my router from my provider is on the other side of my man cave and I want to have all my game systems and both PCs plug Ethernet i have only 1 cable from my router to the man caved for my game rig can I use that 1 port to a switch so I can multiple ethernets without haveing a crazy mess of 75 feet cables from across the room is that possible I’m realllly new to this lol
Yes, a switch would be a perfect solution for that. 😄
Network Advisor what would be the best switch for my solution just wondering I want the best forget a budget 😎also thanks for responding
Cool video. Easy to understand. Thank you.
Thanks for the feedback, Keith. This video has been surprisingly more successful than I expected. 😄
Hahaha well that's great! BTW, do you have any certs? I'm looking to start studying for the CCNA. Just curious if u have any Cisco experience?
@@secretbeach999 I have (had) a few. I had a CCNA once upon a time. I've not renewed it.
The CCNA cert is a good buck/bang ratio in terms of getting your foot in the door. If I was more interested in security, I'd prob go after the CISSP.
But, don't go after a cert for the $$, follow what interests you. :-)
Network Advisor thank you! That's great advice. I'm studying for my CCNA right now. I plan to learn some Linux along the way, along with some Python and then eventually into security =]
wow Great video , cleared all my concepts , Thank you for the content 😄 ,You should probably make a CCNA course.
Ahahaha right? My version of a CCNA course. 🤔
What happens if you directly plug in internet cable into switch?
Your internet hand off only gives one IP address. So even if you had 4 computers plugged into the switch, only ONE would have access to the web.
Spot on. Thanks alot , easily explained.
You're quite welcome. Glad the explanation worked for you. :-)
I sware you have a voice of a James Morgan McGill, also known by his business name Saul Goodman😊
Btw good video.
#bobOdenkirk ? Yes, I get that often. I did watch some Breaking Bad, but never watched Better Call Saul. 😆
Man! I thought roating and switching was difficutly. This seems so simple lol. Im mad at myself for not realizing this sooner
ahaha.. Kevin been there myself with other topics! :-D
Thaaaaaaaaank you!! Finally I understand!
So glad I could help!
Very Understandable video
Thank for presentation
thanks for the Feedback Adnan. :-)
Very east to understand. Thank you!!
can you connect a switch to another switch?
Yes, you sure can. 😊
Great work!
Didn't some company buy Linksys off Cisco? Edit: Belkin seems to be the present owner of them.
is that right Ken? hmm, didn’t know that. thanks for sharing that. 🙂
Hi, says so on the wikipedia. Cisco Systems owned them until 2013 apparently, not 100% sure though. I'll take this opportunity to thank you for all of your videos! I couldn't recall myself,
I've got an IPS Modem, that has Both Wifi and Lan connection. I run one cable towards a Router that also has Wifi and Lan ports. Now I'm gonna Swap the Router with an Switch so I only have to Port forward the IPS Modem and not both the modem and router.
The IPS Modem is on the Ground floor that connects the Router on the 2nd floor Attic and the router connected to my PC.
Or i could just buy an 40M UTP Cable instead of the 2 20M I've got.
Sounds like you have a plan! 👍🙂
dump switch or dump Hub?
Naga, it's a dumb switch. Here in the US, dumb hubs are getting hard to find. ;-)
dumptruck
Ahhhh!! Thank you for the explanation! I subbed!
Thanks Sir, Great Video.
Kindly Make Video On Different Ethernet Technologies Eg. 10G, 100G etc If Possible.
Pratik. Thanks for the suggestion. I'll think about that.
And, thanks for watching!
Thanks for for the clarification. One question: Are all the cables you're using "ethernet" cables? Are certain cables different colors? I've seen ethernet cables typically being yellow and blue.
Mr Meh Ethernet cable color may vary.
Ethernet cables come in all colors. The colors don't mean anything.
Thanks for the video. It seems that anyone connected directly to the router would get much faster service than those who are sharing the router port via a switch. Is this observation correct?
Generally no. Good modern router is as fast as a switch
This video helped so much
I would love to see a wifi version of this video.
Great explation
Thanks Saul
I know right? I even sent Bob Odenkirk this video on Twitter but never heard back.
Thanks for the video
the only question is.. Does switch have wifi like routers do?
Genreally not, unless the switch is part of a router/swtich/wifi combo. To add Wifi to a network, a device called an "Wireless Access Point" is connected to the switch.
Great question, thanks for bringing that up!
finally got a clear definition
Thank you. Others have liked my simple explanation too. Happy that helped 😊
Excellent
Outstanding, thank you.
Glad you like it!
Thanks for the help, but I can't unhear Jimmy Mcgill lmao
Right? I get that sometimes. 😄
Loved it.... I am subscribing it too...
Thanks Ayush. Glad to have you as a subscriber. :)
awesome, thank you man.
glad to help. thanks for watching. 😋
Dear, can you please show us the route of fiber optic cable from OLT to ODF (inside data center) to Optical Splice Closure (inside Manhole) up to user's location?
Thank you
Phenomenal!
thanks for the compliment! :-D
i got it! thank you
Very simple and wrong. Switch isn't dumb, that would be a hub. Switch builds it's own mac tables to route packages to apropriate receiver. It can even have ip routing tables. Router on the other hand is a switch that does ip routing, address translation, dhcp and dns server and physical firewall. Also almost all of them have wifis these days. They also have web interface for management and much more. Main benefit of a switch is that you get way more ports for same price and possibly lower latency.
thanks for you correction. :-)
THANKS!
Just subbed.
Thank you ☺️
New from Cinco!
