Studying via animations is Awesome, Thanks for your effort. Keep doing !!!
Glad you like them!
Awesome video! Great and clear explanation
You are welcome.
Well explained. Excellent
Glad it was helpful!
Subscribed easy choice
Mfer gettin realll complex at the end there 🥴
Thanks you like it.
The best collection of videos I have seen. Thank you
Glad you enjoyed it!
thank you.
You're welcome
Hi Thanks for this video. Very good explaination, just 1 query that in 4:00 min of video you mentioned that MBR can support 14 partitions i am not clear with this portion. Because i know and further you also mentioned in video that MBR support 4 partitions. Please help i am confused in this portion.
MBR supports three types of partition: primary, extended, and logical on a single disk. We can use only primary and logical partitions for data storage. We cannot use the extended partition for data storage. It stores logical partitions. Technically, MBR supports only four primary partitions numbered from 1 to 4. If we need more partitions, we need to convert the last primary partition into the extended partition. Inside the extended partition, we can create up to 11 logical partitions. Thus, we can create a maximum of 14 usable partitions (3 primary and 11 logical) on a single disk. The numbering for the logical partitions starts at 5.
networkmanager now stores config files in: /etc/NetworkManager/system-connections
Very clear video thank you helpd alot..
Glad it helped
Very helpful content
Glad you think so!
The part where you said 'choose these for desktop' really helped. I was getting stuck over and over before watching your video. Thank you so much! Namaste.
You are welcome!
çok teşekkürler, sizlere mail gönderdim sorularımı cevaplandırma şansınız olur mu.
Mailinize zaten cevap verdim. Lütfen posta kutunuzu kontrol edin. Teşekkürler.
Great video
Thanks!
I've been trying to figure out how to change the hosts file for 2 days and it keeps giving me errors. You showed me the exact solution I was looking for. Now, I will enter the DNS addresses on the relevant site one by one and try to find the Amazon server with the fastest ping. I liked and subscribed. Thank you.
Glad to know it worked for you
Hi! First of all, great explanation! Second, what would happen if I want both vlans to be able to use the router, but make them unreachable between each other. Like different work departments that will communicate to other networks with that router, but not between them. Hope that makes sense...
Hello, Thanks for your appreciation. Systems in different VLANs can not communicate directly. However, they can communicate within the VLAN. Systems in different VLANs can communicate via a router. If you want to use a router for two or more VLANs as the default gateway while not allowing them to access each other, you need to configure an access list on the router. An access list defines what devices can access through the router.
every interface have IP address?in routing am i right
In routing, router interfaces work as default gateways for local segments. Each router interface need an unique IP address from a different subnet.
@@computernetworkingnotesyoutube Thank you for the reply. If I give the IP address to the system of 192.168.1.1 and can I give the IP to the same router connected switch IP of 192.168.1.254 like means the router has the same network but different host IP. Please guide
Yes, you must assign an IP address from the same subnet to the default gateway router and all devices connected in the subnet. To learn more about host addresses and network addresses, you can check the following tutorial. www.computernetworkingnotes.com/networking-tutorials/ip-address-network-address-and-host-address-explained.html
@@computernetworkingnotesyoutube surely will watch this. Your every video is so worthy ❤️
Very helpful
Glad to hear that
A lot of worth knowledge, thank you for this!
Glad it was helpful!
great video summarizing stp. how can we remove the emoji so that we can take picture
Thanks you like it. Technical videos are complex. Emoji, GIF, animation make them a bit easier.
I took a picture anyway. Thank you for your dedication
Brilliant
Thanks
Really its a great job
Thanks
FYI - GNS3 VM must be in default folder or it may not work!
Not a requirement but it will definitely save you some customization steps. The default settings and locations make things easier.
This is literally the best video for that topic. And pretty good and detailed explanations. Optionally, it would be good to have timekeys for the stuff you've described in the description.
Thanks, will do!
how long does the store-and-forward process take at the switch?
It varies from switch to switch. Switch's hardware is the main factor for it. However, on all switches, it relatively takes more time than the cut-and-through and fragment-free methods.
@@computernetworkingnotesyoutube thank you
Very well explained!! Thank you
You are welcome!
Hello, the IP/Gateway/DNS information you told us to input won't allow me to connect to the internet... I followed everything you said verbatim and still can't get it to work. What should I do?
Hello @nlvon, Instead of using the IP configuration I used in this video, you need to use the IP configuration of your modem. As I explained in the video, different ISPs use different IP addresses as the default Gateway IP address. Use the following steps to fix this issue. Before you start check and verify the Internet connection Access a few websites Use nmtui or ip tools to view the IP configuration Note down the gateway IP and DNS server addresses Use the noted IP addresses to configure a caching-only server
Guys you are the best! Thank you!
Glad to know you like it
I wish strongly that i sat in your classroom to learn knowledge from you.
Glad to know that. You can always learn with us via this channel.
why you haven't used switchport mode access after interfacing.
By default, all switch ports work in access mode. The access mode is the default mode. You do not need to configure it on any port unless you have changed the default mode.
Hi. Why SAS is not on "the type of interfaces" list? Or is it something different?
No, it is not different. It is a type of interface. Computer interfaces are very complex. You could study them for years and still have a lot to learn. So, I described them in the most simplistic terms possible. SAS is similar to SATA. Both use serial transmission to transfer data. Both use the following cable layout. two conductors for sending data two conductors for receiving data Ground cables in between the conductors to reduce interference In a SATA cable, all 4 wires are placed within the same cable. In a SAS cable, the 4 wires are separated into 2 different cables. SAS is generally more expensive, and it’s better suited for use in servers or processing-heavy computer workstations. SATA is less expensive, and it’s better suited for desktop file storage. Since SAS is similar to SATA and less used in personal computers, I explained SATA and skipped SAS to keep this video simple for beginners.
@@computernetworkingnotesyoutube Thank you for detailed answer. I'm newby and I want to become system administrator and get a job in data center someday. But such terms as: SAS / SATA / SCSI / PATA / NVME / PCI are SOOO STRESSFULL for me)) I don't understand absolutely nothing about it)) Maybe someday I will)) Thank you!))
Welcome @operationalemail, You will definitely become a system administrator one day. Hard work always pays. We are here to help you on any topic you think is hard to understand.
A complete video for beginners. Thanks you
You are welcome!
Thank you very easy to understand
You are welcome!
Can’t you use LVM with GPT? I think I saw some KZreadr do that
You can use LVM with GPT. LVM is a partition type while GPT is how the hard disk stores partition information.
Imagine creating a separate partition for every different type of file on your system
Ya, you can do it. But you should create partitions based on your requirement rather than one for each type.
Excellent video, thanks a lot
Glad you liked it!
Best learning video. Thanks a ton!

Hi Bro can you please 🙏make a tutorial on Kerberos & NTLM how it works & how to authenticate using it on windows & Linux also explain different command it has. please its a request.
Sure, I will do it. But it will take some time, maybe a month or two, as I have a few projects already lined up.
just buy more ram^^
An effective but costly solution

Best tutorial I've seen in a while. I came for swap space and learned much more.(round robin). Thank you.
Glad it was helpful!
I’ve been running Linux without swap on 8GB of RAM for about 6 years with an SSD and btrfs. No complaints here. [Edit: Photoshop and Vim taking up that much space 😂 what world do you live in?]
Thanks for your feedback, Ya, of course, you can run Linux without swap space. As I mentioned in the video, Linux uses the swap space only when it has a shortage of RAM. If all running applications use RAM below the threshold value, Linux does not use the swap space. So far, the values for Photoshop and Vim used in the video are concerned; they are only for explanation. They have nothing to do with the actual RAM they use.
Runs Linux -> starts Photoshop 😅
Thanks for your feedback, Application names used in this video are only for explanation. You can think of any application. So far, Photoshop is concerned; it does not support Linux directly. If you want to install and run Photoshop on Linux, you can do it through the Wine package. It allows you to run any Windows-based software.
Great video! Wouldn't the 'paging space/memory' be exactly the same as 'swap space'? More likely in Windows terms :)
Yes, exactly
nice explanation
Thanks and welcome
greate
thanks for your feedback
Thank you, it is helpful.
You are welcome!
Thanks but I have one simple problem. How will I use repos for apps if I'm not registered? The way you told us to setup network doesn't allow me to register my redhead account so I have no access to repos. Please help
I set up this lab to practice RHCE/RHCSA exam topics. Since candidates are not allowed to use the Internet during the exam, I did not configure the system to use the Internet. If you have an RHN account and want to download apps from RHN repositories, you can configure the system to use the RHN network. You can do this during the installation or after the installation.
@@computernetworkingnotesyoutube I want to practice Ansible. How can I do that without having access to internet? I’m trying to practice for the RHCE as well. I already have my RHCSA but i practiced using CentOS in the past.
@Crowncity If you need the Internet on a virtual machine, you need to change its connection type to bridge and adjust the IP configuration on the virtual machine based on the Internet connection available on the host system. After doing the activity that needs the Internet, you can switch back to the original state. For example, I also needed an Internet connection to explain the DNS server. So, I connected my virtual machines to the Internet and switched back to the original state after explaining the topic. You can watch the following video to learn how to change the network connection. kzread.info/dash/bejne/paSAsZeJpK7ZfZs.htmlsi=2S_sRpodG9-g2ttB
