[@MPnoir]

You could have mentioned that all those things operate on different layers. A hub works on layer 1 is practically just sticking several cables together. So a hub does nothing smart. It's just physically splitting the cables, which then of course results in lots of packet collisions, when two devices send at the same time. Also all devices get all the traffic, which might not be what you want. So this works on a very small scale, but the more devices are tied together like that the worse it gets. A switch works on layer 2 (with the ethernet protocol) and addresses the devices by the MAC address. Thus you reduce the packet collisions and devices only get these frames that where meant for them. But a switch does not do any actual (IP based) routing, and because of that devices on a switch need to be on the same subnet to be able to communicate which each other without the help of a router. A router works on layer 3 (with the IP protocol) and addresses the devices by their IP address. And a router does actual routing, as in it has a routing table and knows which packet belongs where. It also knows the gateway(s) for outbound traffic. If you want to know more about that read up on the OSI layer model. Another thing that i would like to point out: Those things at home that we usually call routers aren't actually (just) routers.They are a combination of a modem, often a wifi access point, DHCP servers and yes also a router. And while they did mention that i don't think they made it clear enough. Because an actual router does just that: It routes traffic. And it does that by looking at the destination IP in an incoming packet, looks at a routing table to see where it needs to send it and then sends it that way. A router does just that. Not more, not less. I hope that clears up a bit of the confusion in the comments as to why sometimes you just need a modem or a router and a modem or just a router. It's because those "routers" aren't just routers. To connect several devices to the internet you need at least a modem and a router. But often those things are combined into one box.

[@perimiter]

i am a little confused ,how do routers and switches connect together? do i connect the modem to the switch ? or do i connect the modem to the router and then to the switch? for example lets say i am building a new house, it has two floors. the contractor lined cables from the basement to each of the rooms and the ISP installed a modem down in the basement . now how do i proceed? should i connect the switch to the modem ? or do i need to connect the router to the modem and the switch?

[@kalijasin]

@peri, connect the modem to a router if you want to share the internet.

[@SivaKanthSharma]

So for a home network connected to one broadband cable, it goes, broadband- modem -router- switch- connected devices. Am I right? And an access point between switch and device if it's a wireless connection

[@SaisBlade]

Thanks for the Clarification bu OSI layer- its helpful. One thing I dont understand: you said that a switch works with mac addresses and not ips, thus devices need to be on the same subnet to communicate. Since the switch cant "know" about subnets if it works on layer 2 - how can subnets be a consideration here? Assuming a (weird) scenario where 2 devices directly connected to a switch are on different subnets (or not assigned ips at all) - Whats stopping them from addressing each other by MAC address and sending ethernet frames on the switch? Is it an address resolution problem?

[@tofu_golem]

As an IT guy, I apologize for the confusing lingo. Hub = non-switched hub Switch = switched hub They are both hubs. The one that is switched is called a switch and the one that isn't is called a hub. When they first started showing up, they were expensive and used sparingly and careful in office networks.

[@AyantikaTEN10]

Access Point, WiFi Extender, WiFi Repeater Are these all the same thing?

[@cchen7452]

For people who think that modems are old/outdated, they're always required unless you have fiber optics at home. Then you get to choose between a fiber modem(cheaper) or a layer 2 switch with SFP ports(more expensive)

I would actually mention DHCP server as an integral part of a router, as the primary function of a router is not giving out private IP addresses but rather perform NAT (Network Address Translation) tasks between the internal network (with your PC, phone, tablets and fridges in it) and external one (Internet connection). Oftentimes DHCP servers are installed separately from routers for better performance and administration.

Dmitry Granicin the main purpose of a router is to route, do not mix concepts.

Fiber doesn't use a "modem". Your ONT converts the fiber light wavelength into Ethernet or MoCA that your router connects to.

What about Managed vs Unmanaged switches?

[@tubastud06]

Well... Pretty much the only difference is a managed switch is - Managed. All that's going on in a managed switch is you are controlling what ports do, configuring trunking for VLANs or port teaming. Unmanaged switches that you pick up off the shelf in big box stores are "managed" by the layer 3 device that they are connected to. All (Layer 2) switches perform the same function: Store MAC addresses of client devices in a table so that they can be "smart" and forward information to an individual destination. This is the big difference between hubs and switches, hubs are "bit spitters" where each port repeats the same information - With switches, only the destination port is getting the traffic.

[@sundhaug92]

To append to what Ke B said: Unless you know you need a managed switch, you probably only need an unmanaged switch

Wireless Access Point = AP Why is it not WAP Or did you just forget the wireless bit , that bit is quite important

[@junsnow4002]

because WAP is a protocol and AP is a device

[@jadesmith8106]

And an AP can be wireless or connected to the modem router by ethernet cable. So, the proper name would then be "wire(less) Access Point" Not to confuse people they just called it wireless, but you will have an ethernet port on the device. Btw Modem means "modelator-demodelator" and WAP would mean "wireless application protocol"

[@tonalddrumpboe5151]

Modem receives data from the ISP over some sort of cable or voa air. Router creates and assign IP adresses to every device in your local network. Switches provides multiple ports and is essentially a hub but better with no congestion . Access points is wifi that you can connect to

So if I run a Ethernet cable from my router to my room and connect it to a switch will I be able to use my pc and my Xbox at the same time

[@Bruce.-Wayne]

Of course you can....

[@brycegriffin9271]

You wouldn't even need the switch. You would just need to connect the Ethernet cable directly from the router to the Xbox. All a switch does is expand the number of wired devices on the network. Say you run a big business and need 20 access points, a firewall, and a couple servers, you could get a 48 port switch and run Ethernet cables from those devices to the switch and then the switch to the router and they would all run at much higher speeds since they're on your LAN (think wired network) rather than your WAN (think wifi). When you run an Ethernet cable to your router, what you're actually doing is running an Ethernet cable to an onboard switch that communicates with your router, so it's effectively the same thing.

In routers it's used to automatically open firewall ports to allow devices on your network to do what they need to do. It's fairly insecure as it assumes nothing inside your network is malicious. If you were to get malware, it could potentially open up any port on your firewall that it wanted to.

simple, just make everything wired. wired is the fastest way to go, even if you have gigabit speeds. alot of that will degrade due to the nature of wireless signals and its vulnerabilities to interference and range limitations. if you want the fastest speeds possible, just wire all that shit up! i handle this by plugging in switches and running them to each room of my house. speeds aht are as if i was plugged directly into my router, none of the latency. and for devices like phones that HAVE to be wireless, you also have the option of buying better antennas for your router and even running them with extra long cable to various points in your house.

Thank you sir very much for your explanation A modem, e.g. a switch is the ISP, the internet provider, which the ethernet cable is connected, transmitting internet from your local provider through fiber optics for example a router typically is a disseminator of the internet connected by a LAN cable to your Modem, your ISP (a switch here) a router is useful when you try to have access to internet in all three floors of a building, one router for each floor You can think of the router as a bridge between the Modem and you, wanting to watch videos about routers I think the video also mentioned inbound and outbound, which maybe interpreted as input and output, like similar to those, so you connect your Modem and a router through a LAN cable, the inbound here might mean the internet being transmitted from the switch to the router, in from the switch to the router and then outbound is, the internet being out through the router correct me please if anything

[@chemedev]

You should NEVER connect directly to a modem and dismiss the router even if you got just 1 wired device. Reason? Security. Besides, you can always turn your SOHO router (ISP) into bridge mode and use other router if you want a better performance one.

[@cchen7452]

Juan Chemell consumer routers have almost no security features other than NAT, but they usually come with upnp enabled which let applications forward their own ports. If one of those applications has security issues the entire lan can be compromised pretty quickly. A hardware firewall/UTM/security gateway with proper firewall rules and intrusion detection is what you need.

[@lostevesy]

Bryce Swain In the UK they're just called routers, no modem needed, just buy any off the shelf router and plug your phone line into it. I guess it may have something to do with getting internet from cable .. as our routers don't have any cable attachment, not sure.

[@AgentSquirrelA]

Lost Evesy If you are plugging a phone line into it, it has a modem built in.

[@DumbSloth87]

Yeah, if there's either a RJ11 (telephone) or Coaxial connector, it's a modem. And if yours also had several Ethernet ports on the back and Wi-Fi, that means it sucks at doing all of those things, specially Wi-Fi.

[@Fibonacci11235]

Lost Evesy The real reason is how modems are distributed in the US. Currently, US ISPs provide the modem (often charging a fee for it) and in some cases, a router is built in. While I am not sure about the exact situation, my guess would be that in the UK, since you purchase your own modem, they likely often come with an additional router built in. It's kind of similar in the US, since most "routers" you find for consumers are actually a combined router, access point, and network switch. TLDR; my guess is that modems in the UK bundle a modem router, wireless access point, and network switch all into one package.

[@Fuzzel]

What you said a router would do is actually just the function of a NAT box which often are inside a router, before the actual "router" part can do stuff like subnetting and "routing" It goes (WAN)-> Modem -> N(P)AT-Box -> Router -> [Switch] -> End-Device

[@solath]

I know there is always an effort to Keep It Simple but goodness Linus! 1. A modem is only needed if your ISP is providing you an analog signal. The word 'modem' derives from 'modulation' and 'demodulation'. More and more providers are handing you a digital signal already (at least in the states). 2. You talked about routers and didn't even mention your own videos on PFSense? 3. Why would you want to pass up a hub? They haven't been made in years and are very hard to find. If you are a home-gamer and want to analyze network traffic to and from a device then a hub makes that a breeze. If you want to do that sort of analysis without a hub then you're talking a managed switch...and even some of those won't mirror ports.

Any device that translates between your ISP's incoming signal (Cable/DSL/Fiber) and Ethernet is still called a modem. Such a device is always needed, but often built into a router. With fiber, it's typically called the ONT but still does the same job.

[@solath]

You should google the word 'modem'. I have facilities that receive digital bandwidth from an ISP that connects directly to a F/E router port (no modem). I work with a number of AVPN/MPLS data lines that also connect directly to routers with no built-in modem. I believe the Linus Media Group brings fiber optic directly from their ISP into their PFSense router (watch the videos). BTW, an Optical Network Terminal (ONT) is a fancy term for a media converter.

[@zacmurphy9995]

Great video! It really helped clarify the differences between all the devices that I need to learn for ICT A-Level.

[@alexisabakasanga]

The energy in your videos are awesome!

[@bronsoneagle2438]

Would love for you guess to touch on this again, maybe throw in hubs and gateways.

[@mayankमोनंटि]

I'm just watching this video because I router vs switch is a question I need to answer in my interview today

[@at0mac]

these days im starting to feel old. we are close to the same age Linus, so I too have been using internet over hubs and used to store data on Iomega Zip and Zip+ drives... those were the days... now I have a home network with a wired only router, a wired POE switch, an POE powered wireless AP and multiple QOS enabled local switches around the house for full gigabit network. That system rocks compared to one-box solutions.

[@AgentSquirrelA]

A modem isn't required if you aren't modulating and demodulating (Mo-Dem) a signal. You can just use a Router in these cases.

[@Hubjeep]

Thank you for the video. I am in the process of buying a POE switch, 4-5 POE wireless access points, to provide internet for a large concrete house, which now has 3 routers with all different logins/passwords... trying to get them to hand-off with one login/PW.

[@pijen]

all those technicians at my workplace should watch this video. they casually calls everything a modem even though what they meant was either router, network switch, wireless AP or the modem itself.

[@russemerson4872]

As an old CCIE, I'll just say: well done.

[@xminecrafter115]

how long did it take to get your ccie

[@russemerson4872]

I finished college and started working at Cisco in 1996; got my certification in 1998. I did the then-new ISP-Dial version, was the 6th to get it.

[@xminecrafter115]

1998 damb, i wasnt even born yet, im 17 just starting out about to take the ccent

[@TechPorkChop]

Start with ICND1, then go for ICND2. Pass those 2 tests and you become a CCNA. The CCNA 1 test is for people renewing their certifications.

[@christiancarnahan1930]

Hello, I run a business and have up to 30-40 phones on a 2.4ghz network in a close proximity. What is the best option to keep a decent speed and lower or eliminate the disconnects?

[@nicholaslepp1502]

here because i just scored a buffalo airstation with ac and a netgear auto switch for $20 usd from a stranger on the internet in 2019. thanks mitch. lol

[@icecreamjunkie6790]

Nowadays it’s more common to have a gateway. A gateway combines a router, modem, and access point.

[@waalex11]

Still researching but I guess I want an access point to expand the wireless part of my modem... and not a router because that's not technically for wireless.

[@MadSpacePig]

We don't have separate Modems in the UK, everything is ADSL.

[@comicsansgreenkirby]

I have a HP d350 SFF running DOS. I also have a couple Acer Veriton M series computers. One of them I installed a floppy drive on. I may have fried the floppy drive I/O controller, so I put it in my sister's computer. I also fried my 3-pin fan header. I thought the motherboard also adjusted fan speed on a system fan. So I connected a battery tester to a connector. Unfortunately, the 2 exposed wires connecting the battery tester had touched each other just enough to make a snap and some yellowish-orange sparks with no flames, but a grey burnt look on the header. No more of that type of cooling, unless I can get a SATA power to fan connector.

[@happytorrentt4500]

I was at Walmart the other day, and I was in the electronics sections looking at random junk. Literally on this one lonely isle with barely anything, right behind a few WiFi routers was a hub. The box looked like it belonged in Indiana Jones

[@abhisheklagad3694]

own ads on own channel is next level flex

[@mosesmukambojr8707]

Please do a buying guide on wireless router antennas. I have a wireless router in a place with poor network. Would getting a router antenna help and which one should i choose.

[@rodris01]

Can you do a video about the differences between managed and unmanaged switches for home networks? So many options when it comes to switches.

[@jeroenfigee]

Love, love your videos as they give tonss of great info and really fun to watch and listen to. Great channel and lots of tumbs up from me. But the way you pronounce router... well lets all sing along... "you get your kicks on route 66" okay great ! How did you pronounce that one ?? lol - the same ???
