Down promote Snake Oil! As a private person you only need the Virus Detector of your operating system. The ones that get hacked are Companys and Smart Home Devices where you cant install a Virus Detector.
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.
dude saaaame. I had a whole year after i quit my insurance job where i was not working but was studying IT and watching these videos and seeing these videos brings back the feelings i had at the time of relief being out of insurance claims and hope/excitement beginning my journey into IT.
PS: I am now a Network Admin and have been for 2 years!
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.
Correct
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 CZcams tutorials.
Your lessons are pure genius!
You actually made Networking easy for me to understand ... Thank You very much and keep up the good work
Glad to hear that
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.
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!
ah man thx..nostalgia when we learnt that back in highschool😭😭
keep the work 🔥🔥
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.
There were discontinued. But you can still find some out there being used.
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.
This is a visual implementation of theory not actual implementation
These collision domains are similar to a DDos attack.
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?
Interesting!!!Thank you for the information and keep it up!! I need this in order to study for Comptia A+!!!
Glad it was helpful!
You create a great animation for understanding.....i study networking and core A+ from your video.... it's very helpful for me thank you
Preparing for my network+, great explanation.
Thank you so much for the clear explanation I have ever seen, I have downloaded all your video in half hour
Good simplified video. Keep them coming!!!!
You are back, after a long time. 😃
i'm really thankful, i love those videos of yours
All your vids are great !!
Thank you so much for these videos. They clear up so much.
I love this channel so much. I have seen every single video, keep it coming ...
Thank you! Will do!
Nice, Thank you for all your informative videos.
Can you please do a video of what is a packet / frame for Networking?
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.👍😂
Hey! Thanks for the new video! And you got a sponsor, awesome!!
Hey, thanks!
Thanks for the valid information
Nicely explained 😊
Another perfect video, thank you
Glad you enjoyed it!
Always an instant watch
Great video!👍🏽👍🏽
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
Thanks for the video. Great
Thank you❤
well done!
I want to thank you for the information and add that implementing a vlan, subnetting and ACLs would also stop broadcast domain 😊
I didn't know this man had humongous knowledge on networking kudos sir❤
Awesome Video.Thanks❤
You're welcome 😊
Thank you so much
You are the best!
Great! Thank you for making such understandable videos. Can u please make videos on STP in detail and Routing protocols
Noted
He's baccccck
I was wondering if you have a video explaining the osi model vs the tcp/ip stack
Just to add, beside a router, also creating vlans on the switch can create different broadcast domains since each vlan is a separate broadcast
Thank you. What about a course on SDWAN and the difference with MPLS?
Thx
This is cool, and didn’t know this technology existed. Cool tho, glad we came a long way from hubs to switches.
Sir I am watching your videos since a long time. I want to see you..
Hail PowerCertAnimatedVideos and Routers.
When this channel upload the video I very galad
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!
Could a Proxy Server help with managing bandwidth amounts when a router is added?
Hoping for your video of Routing Protocols like Ospf, Eigrp, Rip and static
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?
No fires? Challenge accepted!
lmaoo
I preferred VLANs instead of physical routers.
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.
You still need a router to connect the VLANs, exactly the same as you would with separate LANs.
HI .Which software you use to Animate videos ?? Nicely Done ✅
can you explaining about bgp and ospf?
Generally speaking, all other factors being equal, will you have more collisions on a network where you need to add more subnets?
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.
how we can broadcast in wan with out connecting any computer
or how radio broadcast work
More videos plz!!
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?
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.
If broadcasts takes way too much CPU usage, consider changing Pentium3 for at least i3 12100
@@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.
My Godfather is back.. waiting for your video
I have a question - If the switchports are full duplex, wouldn't there be 0 collision domains, because there's nowhere to collide?
CompTIA or CISO need to give you an NBA salary to come and remake their instructional content.
Routers will let broadcasts through if you setup a site-to-site VPN.
God bless switches
Do about BGP
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).
are there any reason to still use a hub now a days? even for just a home network
No, they are gone. But it was useful to talk about them when learning about collision domains.
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.
@@James_Knott thank you its very interesting that we used hubs at all looking now at how switches work lol
@@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.
for God's sake, how do you create such videos? which video editor do you use?
👏👏👏
What software do you use to create animations.
Probably Microsoft PowerPoint.
big video :)
"Who designed this network`?"😂
😂😂😂
a video which covers ccna sylllabus is needed
make a video on "how to setup client/server network and peer-to-peer NETWORK" PLZ..
Are hubs still
Used?
I doubt it. There may be some ancient networks still running them, but most networks use routers and switches.
I love somebody's making a video about it as the concept of "switch breaks up collision domains" is really confusing and misleading
Wow, this hurt my head. Too much to take in
:)
👍👍
Fighting and fires breaking out😅
Yaaaaaaaaayy
👍
In the real world, we add vlans not routers
And how do you connect between VLANs without a router?
@@James_Knott A managed switch should be able to connect VLANs.
@@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.
@@James_KnottI can’t see why a device would need to connect between vlans.
@@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.
you had a sponsor just for a 6 min video ? really ? dislike.
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.
Hello MOTHERFUCKER!!!!! IT'S FOR EXPLAINING TO THE PEOPLE WHO WANT TO LEARN NETWORKING MY GUY.
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
