Thanks for your comment. I made this video mainly for beginners. To keep it simple, I intentionally skipped some advanced functionalities that are irrelevant or not required at the primary stage.

Glad you enjoyed it

Computers use ARP protocol to find the MAC addresses of other devices available on the local segment.

Arp packet uses Src ip and dst ip but switch never learn IPs than how come this type of transaction is possible.

@@EffortlessMan Hi, a switch does not need to learn the IP addresses of connected devices. I am not getting what exactly you are asking. Anyway, the whole process goes as the following:- PC1 does not know the MAC address of the destination. PC1 generates an ARP frame to learn the MAC address of the destination. The frame contains the source MAC address (As PC1 knows its own address) and the destination MAC address ( A local broadcast address, as it does not know the destination MAC address) The Frame reaches the switch. The switch adds PC1's MAC address in the CAM table and forwards the frame from all ports except the incoming port. The destination PC replies to the broadcast frame. The reply frame contains the destination PC's MAC address. PC1 learns the MAC address of the destination PC. In this entire process, a switch never needs to learn the IP address. It only needs the MAC address and every frame contains it.

@@computernetworkingnotesyoutube thank you very much. It's clear now

Hello @michaelk.6976, Thanks for your comment. Yes, we can connect two devices with a single IDE cable. But it depends on how many connectors the cable has. If it has two connectors, you can attach one device. If it has three connectors, you can attach two devices using jumpers. I mentioned the two-connector cable as the 40-pin cable and the three-connector cable as the 80-pin cable. So far as pins are concerned, all IDE cables are 40 pins. UDMA cables are 80 wires. The additional 40 wires are ground wires that help to keep the signal cleaner. The difference is in speed/standards. 80-way/pin cables are for ATA 66 and higher speeds, ie HDD. 40-way/pin cables and for ATA 33, ie DVD/CD. To attach two devices with a single cable, you need a three-connector cable. One connector connects to the IDE slot on the motherboard, the second connects to the first IDE device, and the third connects to the second. Regards ComputerNetworkingNotes

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.

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.

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 ❤️

Glad to hear that

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

Thanks

Not a requirement but it will definitely save you some customization steps. The default settings and locations make things easier.
