[@AmbiguousAnthony]

These videos bring me comfort because I used watch these like crazy before entering the IT space. I’m a visual person these videos help so much.

[@AmbiguousAnthony]

@francis6610 that’s awesome bro! Thanks for sharing your story!

[@XYZIV]

A blazing thank you for turning the labyrinth of Networking into a fun and fiery journey! Your videos transformed what felt like navigating a maze of flames into a walk in the park. Learning has never been this entertaining - I never thought data packets could catch fire in a good way! (and not as seen in your graphic examples) Your teaching style is like a fire extinguisher for confusion, putting out the complexity with a burst of clarity and a dash of humor. You've made Networking not just understandable but genuinely enjoyable. So, here's a sizzling THANK YOU for being the fiery maestro of KZbin tutorials. Your lessons are pure genius!

[@Yawsimple]

You actually made Networking easy for me to understand ... Thank You very much and keep up the good work

[@PowerCertAnimatedVideos]

Glad to hear that

[@FinderX]

This easily can be linked to your previous VLAN video, because in real world you don't put psychical routers to split broadcast domains, you should use VLAN interfaces to work like routers and VLAN subnets for the broadcast domains.

[@mayThetubeBewithYou]

Correct

[@Kevin-r7f4u]

VLAN interfaces to work like routers? I thought routers (or even just a routing function on a layer 3 switch) are used to connect separate VLANs together.

[@harishankaryellapragada3180]

100%

[@PeterWhite-ru6qk]

Was waiting for this comment during the whole video

[@DarKUs4224]

I'm preparing for an interview, and your presentations are the best source of knowledge I've come across. I've watched several of your videos already, and I can see the improvement in the presentation quality. Thank you for your work.

[@topgopnik]

OMG man this video was so funny when the WTF! bubble came up at 5:40. Truly made my day. BTW we all know you are from pompano by now!

[@fastslow002]

ah man thx..nostalgia when we learnt that back in highschool😭😭 keep the work 🔥🔥

[@xoneeleven]

I can't imagine that any business or home today even uses a hub. Do they even still make and sell hubs? Hubs are a thing of the 90s.

[@PowerCertAnimatedVideos]

There were discontinued. But you can still find some out there being used.

[@Root3264]

Sometimes in ooooold equipment you need them due to design specifications, so there actually may be still companies that produce them or at least sell old new stock.

[@Bihari_Chaman]

This is a visual implementation of theory not actual implementation

[@garylove2836]

These collision domains are similar to a DDos attack.

[@topgopnik]

Would it not make sense to hub between a modem and PC and a router? I guess you can still use it... even at home what would be the damage if you have 3 PCs wired?

[@olafharoldsonnii4713]

Preparing for my network+, great explanation.

[@noobkar4090]

You create a great animation for understanding.....i study networking and core A+ from your video.... it's very helpful for me thank you

[@chromerims]

Another perfect video, thank you

[@PowerCertAnimatedVideos]

Glad you enjoyed it!

[@extremelydave]

Good simplified video. Keep them coming!!!!

[@aqoonmaalmedia3828]

I want to thank you for the information and add that implementing a vlan, subnetting and ACLs would also stop broadcast domain 😊

[@centro8894]

i'm really thankful, i love those videos of yours

[@user-jt8qn6bn9i]

Can you please do a video of what is a packet / frame for Networking?

[@robertjr8205]

Thank you so much for these videos. They clear up so much.

[@NandoP07]

Hey! Thanks for the new video! And you got a sponsor, awesome!!

[@PowerCertAnimatedVideos]

Hey, thanks!

[@shoroqahmad2599]

that's the best explanation I've ever seeen, thanks a lot :)

Nice, Thank you for all your informative videos.

[@AngeloMagallanes-b8k]

How often do the computers send out a broadcast looking for the computer they're looking for? Are they constantly sending out broadcasts? Do computers not have a memory for who owns what addresses? Love this channel so much... 🤯🤯🤯🤯

[@Kevin-r7f4u]

Still studying networking myself, but a common type of broadcast is ARP (which powercert has another video of). In short, a computer will perform an ARP broadcast when it needs the MAC address of another computer so that it can communicate with that computer. Once the first computer learns that MAC address, it will store it in its ARP cache (kinda like a list of IP addressed matched with corresponding MAC addresses). However, this kind of entry into the cache is temporary (dynamic) and will get purged regularly. If you want it to be more permanent, you have to create a static entry in the ARP cache for that computer. Maybe there are other types of broadcasts, but I still need to learn about them lol.

[@Vickytori22]

I love your videos! They are so helpful! I know you have a complete video on A+ and Network+. Could you also look into doing one for Security+ and CySA+ please? As they really help me! Thank you so much xx

[@wonuwonu17]

thank you!!! subscribed!

[@mathsexplained3434]

Just to add, beside a router, also creating vlans on the switch can create different broadcast domains since each vlan is a separate broadcast

[@brandonfarfan1978]

Thanks for this video. If Eli the computer guy saw this vid, and saw that hubs are being used in it, he would be screaming in IT agony. Lol!👍😂 5:51 Nice fire joke.👍😂

You are the best!

[@anthonynye1747]

This is cool, and didn’t know this technology existed. Cool tho, glad we came a long way from hubs to switches.

[@sayedaliyahyaazhar4218]

Collision Domain: Think of it like this: Imagine a single-lane road where only one car can move at a time. If two cars try to go together, they crash, causing a delay. In Networking Terms: A collision domain is like that road, where devices (like cars) might "collide" if they try to send data at the same time on the network. Broadcast Domain: Think of it like this: Picture a room where if someone speaks on a microphone, everyone in the room can hear it. In Networking Terms: A broadcast domain is like that room, where broadcast messages (like announcements) reach all devices connected to the same network. In essence, a collision domain is about potential conflicts when devices try to talk at the same time (like cars colliding on a narrow road). A broadcast domain is about messages that reach everyone in a shared space (similar to announcements in a room).

[@rahultist]

Awesome Video.Thanks❤

[@PowerCertAnimatedVideos]

You're welcome 😊

[@gayatrishinde5299]

Great! Thank you for making such understandable videos. Can u please make videos on STP in detail and Routing protocols

[@PowerCertAnimatedVideos]

Noted

[@ahmad-murery]

I didn't know of the consequences of having a large network, but still the question is, besides the number of devices, what other factors are involved? I think the switch performance, connection bandwidth, cable types, cable length and maybe the network utilization rate. Really great video as expected, Thanks!

[@MrNrparthiban]

You are so amazing❤

[@lakesideaquatics]

well done!

[@James_Knott]

The problem with broadcasts is not the bandwidth used on the network, but rather the device that receives the broadcast has to stop what it's doing to process the broadcast, determine if it's for it, etc.. One thing that reduces this is multicasts, which are addressed to specific groups and they can be examined and possibly be ignored in the network interface, without having to bother the device. Multicasts are often used in IPv4 but mandatory with IPv6, where broadcasts are not allowed. Also, hubs have been obsolete for many years.

[@volodumurkalunyak4651]

If broadcasts takes way too much CPU usage, consider changing Pentium3 for at least i3 12100

[@James_Knott]

@@volodumurkalunyak4651 Actually, the solution, other than smaller broadcast zones, is multicasts, which only interrupt intended devices. Multicasts are often used on IPv4 and mandatory on IPv6.

[@claussanta2341]

Hail PowerCertAnimatedVideos and Routers.

[@tabishparvez5873]

Sir I am watching your videos since a long time. I want to see you..

[@allie-yj2tz]

Thank you so much

[@craigjovanovich6450]

No fires? Challenge accepted!

[@benque7491]

lmaoo

[@michaelc6031]

Could a Proxy Server help with managing bandwidth amounts when a router is added?

[@cydia6758]

I preferred VLANs instead of physical routers.

[@UmVtCg]

Altough each VLAN is it's own broadcast domain. VLANS operate on layer 2 of the OSI model (801.1q) and have nothing to do with routers.

[@James_Knott]

You still need a router to connect the VLANs, exactly the same as you would with separate LANs.

[@saman_729es]

When this channel upload the video I very galad

[@yahyaosmakdown3847]

[@beewilly4]

I was wondering if you have a video explaining the osi model vs the tcp/ip stack

[@luigigaminglp]

Routers will let broadcasts through if you setup a site-to-site VPN.

[@benque7491]

I love somebody's making a video about it as the concept of "switch breaks up collision domains" is really confusing and misleading

[@herbo_lario]

Could the multiple broadcast issue happen on a network where all devices are connected to a single router? or is it only a switch related issue?

[@felix936vario]

So is there a fixed amount of PCs that can/should be in a broadcast domain? Are we talking about ten Clients or 100 Clients or more? Is there a rule of thumb?

[@W8RIT1]

Generally speaking, all other factors being equal, will you have more collisions on a network where you need to add more subnets?

[@James_Knott]

These days, you shouldn't see collisions. With switches, networks are normally full duplex and with newer switches you can't even force them to be half duplex.

[@shrimpyraccoon]

big video :)

[@chilledoutgamer3232]

I have a question - If the switchports are full duplex, wouldn't there be 0 collision domains, because there's nowhere to collide?

[@clasesutnfrc8699]

03:33 Broadcast domain

[@lessygasela1564]

Are VLANs broadcast domains?

[@hipstersavy]

are there any reason to still use a hub now a days? even for just a home network

[@PowerCertAnimatedVideos]

No, they are gone. But it was useful to talk about them when learning about collision domains.

[@James_Knott]

Not really. In addition to being half duplex, almost all hubs are 10 Mb. There were some 100 Mb hubs, but they appeared around the time switches were becoming popular and quickly disappeared.

[@hipstersavy]

@@James_Knott thank you its very interesting that we used hubs at all looking now at how switches work lol

[@James_Knott]

@@hipstersavy You have to know a bit about the history of Ethernet. Originally, it was a bus network, with all the devices strung out along a coaxial cable, with terminators at each end. Then a company called StarLAN created a version of Ethernet that used existing CAT 3 telephone cable in offices, instead of coax. At the point where all those cables terminated they needed something to connect them together. They came up with a hub which emulated the coax based networks. Switches came later and evolved from bridges, which were used to join segments of coax together. Also, those coax networks had a maximum end to end length and a bridge would allow a whole other section of cable.

Are hubs still Used?

[@JJFlores197]

I doubt it. There may be some ancient networks still running them, but most networks use routers and switches.

[@mikereese15]

[@TJK50014]

Does anyone even sell hubs anymore? I have used nothing but switches since 2005.

[@PowerCertAnimatedVideos]

[@IlPookiell]

In the real world, we add vlans not routers

[@James_Knott]

And how do you connect between VLANs without a router?

[@Eternal_Tech]

@@James_Knott A managed switch should be able to connect VLANs.

[@James_Knott]

@@Eternal_Tech Only if the switch can also do layer 3 switching. That is it can forward based on IP addresses, rather than MAC addresses. A layer 3 switch is functionally equivalent to a router in that both forward based on the IP address.

[@IlPookiell]

@@James_KnottI can’t see why a device would need to connect between vlans.

[@James_Knott]

@@IlPookiell Maybe someone on one VLAN needs to access something on another VLAN? Think of a large office. The LAN could be divided into separate VLANs for different departments. While most of the traffic in one department is within their VLAN, they might still need to access something in another. For example, someone in accounting might need to access servers in HR. Having VLANs, in addition to reducing the broadcast domain also provides a point where controls can be introduced to limit access between areas. For example, on my home network, I have a guest WiFi, which I do not want to allow access to my main network. The guest SSID uses VLAN3 to reach my router, over the same cable and switch port as my main WiFi. My router is then configured to allow guests to access the Internet, but not my main LAN. On the other hand I, on my main LAN, can still access anything on the guest network. Another example would be a network I set up in a senior citizens residence a few years ago. There was the main office LAN, VoIP VLAN for the office phones, a VLAN for resident Internet access and a management VLAN, for accessing the various network devices, such as routers and switches. The residents were only allowed to access the Internet. Average users in the office can access the resources in the office and Internet, but the guy who ran the network could access anything, including the routers and switches. This was all done with VLANs, except for the office LAN, which was native LAN. In addition the office computers were connected through the VoIP phones, with the phones passing on the native LAN to the computers.

[@yunusx3183]

you had a sponsor just for a 6 min video ? really ? dislike.

[@pehenry]

What the hell is the point of this in 2024? You couldn’t buy a “hub” or a “bridge” if you wanted to. And no I didn’t watch the video.

[@Visal898loveminecraft]

Hello MOTHERFUCKER!!!!! IT'S FOR EXPLAINING TO THE PEOPLE WHO WANT TO LEARN NETWORKING MY GUY.

[@benque7491]

Despite replaced in modern networks, hubs were still an important mildstone in networking and the concept of collision domain left as a remnant of hub. If you're going for network certifications you gotta be familiar with hub and the concept of collision domain, not bullshitting in a comment section of somebody's well made video
