This really helped me. I passed CCNA and work as a network engineer and still find myself thinking "Frame or packet??". This is really clear and helpful. Thank you. Just subscribed too.
I’ve watched plenty of videos on this topic. For a newb such as myself, you hit on aspects that seem implied but not taught by others. This cleared up a lot of fuzzy knowledge I had. Super helpful.
Tell me about it!!! I am using Coursera right now and while it is good information, it is proving difficult to understand. I will definitely be using this youtuber to supplement my Certification Training.
finally i understood how the mac is used in combination with ip. Thank you very much. And for those wondering how to obtain the MAC/IP combination of local device (eg. the gateway), the answer is the Access Resolution Protocol (ARP). for a practical overwiev in Windows: open commandline (cmd or powershell ) and run first IPCONFIG and afterwards ARP -A
After searching for this exact explanation for days, I finally land on this video . Thankyou for the simple yet comprehensive approach. Now I just need to add in the protocols.
I have been searching for this for days! A simple but understandable explanation to cover the basics for people who are just learning. Thank you so much!
This was the best explanation of how data moves. No professor, textbook, or expensive learning package on these training websites can do what you just did.
Wow i never saw a teacher like you , u are really great In India we dont thought this must clearly but u made my day really so happy to learn from you thanks buddy lots of love from India
Thank you for this!!!!! I loved it!! I'm a very visual learner and I couldn't understand this concept until I saw this. Thanks a mil for saving me and helping me understand my coursework!!
Cleared some fundamnetals...Especially the part at the router where the frame is changed but the packets remain same. Everything now falls into place. Thanks a million
Was looking for something to explain this to a colleague. This fit perfectly. Thankyou. One NitPick: around the 6:00 point, you decapsulate the IP packet from the Ethernet Frame, then put it back into the same Frame. I think it would be clearer if you scrap the old Frame and create a new one with Src-MAC of the router port and the Dest-Mac of the final host. Still one of the clearest videos i could find online. Thanks!
Hear me out with this analogy. I see this as me sending out a letter (packet), which in this case my computer IP is my address, and the recipient's IP is where the letter is addressed to. Before I can send it I package the envelope into a FedEx box that has the FedEx tracking number (the Mac address). Once the package is received to the truck driver (the network), he scans the tracking number and takes it to the warehouse (router). The only deviation here is that the warehouse takes that tracking number, and assigns it a new one (other Mac address, which is now picked up and scanned by a second truck driver (2nd network) to get it delivered to the new address (2nd Mac address). The recipient then opens the package to find his name on it (his IP address). Hope this helped and not confused anyone.
I love this man. I’ve been searching for 2 days for explanation like this. Now I understand how mac address change in IP route 😋 instantly subcribed ☺️
FINALLY!!! I've taken tons of college classes and even tried the Cisco CCNA program last year and could never quite make sense out of this process until now! Why is it so hard for so many professionals to break it down like this where the process makes sense? Cisco should let you overhaul their program! Subscribed!
HONESTLY, I'm in college right now and its a class I need to take. I'm in the netcad Cisco program but honestly its not this clear and simple!!! These videos help me understand it so clearly and simple compared to that cisco class/course!! Wish me luck!
Deez Skates the latest CCNA does go into visualizing how frames get forwarded in a network quite extensively. I agree with you that nailing it down is absolutely crucial in understanding networks, especially from a troubleshooting perspective. To give an example. One time, random hosts on the LAN were getting a 169 address. My boss told me that it’s probably the switch or the cabling. But I was explaining it to him that it has something to do with the firewall (dhcp server). Because a bad uplink cable would cut off everyone. You can’t have some hosts working and some not on a faulty ethernet cable, because the frames are multiplexed across a single pair of wires. The example is to illustrate that troubleshooting requires understanding the details of the technology. Also another time it happened, he was fiddling with the modem. I explained to him that a bad WAN connection can’t cut off your local IP address assignments.
Thanks Jacob. This explain how the switch and router works together to communicate. I am studying my materials for CCNA and the tutor just doesn’t mentioned the encapsulation and decapsulation of it.
I find this video most useful, it has explained all the concepts in a very simple way. Thank you so much for the efforts you have put to make this video!!
I saw so many videos to understand these things, but none are completely clear. So I thought of making a video after I understand it clearly, but you made it.
@Ivy Yeah anyone that doesn't design, maintain or build engines isn't a real engineer! The English language never evolves to expand the scope of a term...
Useful video. I particularly liked the way you explained how the data is encapsulated to a packet and to Frame... how the new frame is created at the router level.. Thanks for creating such videos.
Thanks for posting i am currently taking google IT course and there is a quiz on routing and subnet masks that is frankly confusing thanks for adding a little clarity .
When the video started I thought that this is a random video and when watching till the first minute I have subscribed. Cause your teaching method is very very attractive. Thanks brother..❤❤ From Sri Lanka
But there is one thing I don't understand : In this video the default gateway is in your house. But your gateway does not know the destination mac adress, yet in this video he says it does? I think only the router in the destinations network knows the final destination mac address??
superb tutorial. you break it down in the most simple way. Hope to see you this same presentation adding the 7/internet OSI layers please. Though i have the idea of those 7 osi layers i can't break it down well. Thanks.
This was exactly what I needed. I am a Junior Datacenter Architect covering HCI and Virtualization. and Its been hell trying to learn just enough of the other categories, such as networking without spending a ridiculous amount of time doing those certifications. This video covered exactly what i needed to know, and explained it as if i am coming from nothing.
Thank you loads for the help. You explain the whole thing simple and very clearly. I watched your other videos related to the IPV4 . They also same as this. Thank you again. Keep the good work up. 😁
A hint, when you box, unbox the data => packet => frame => wire , you could draw horizontal lines with the OSI Layers. this way its easy to understand why switches operate with frames at Layer 2, Routers at Layer 3 with packets, and your (skype/whatever app) at top Layer with Data.
you must be a genius, am trying to get ccent exams . you break everything down for me to understand. thanks alot. i had to even go and check if you guys offer thoses cause so i can take from you guys. will love to subscribe to your chenel for more studies
At layer 3 the data is in the form of a packet (L3PDU) . The packet is then encapsulated with a Header and Trailer at layer 2and is transmitted as a Frame.
the only thing, isnt when the router gets the packet from its incoming int, going towards the right host. would the source MAC be G0/0, and the source would be G0/1.. not host 2s MAC? As when the packet gets to int G0/1, it THEN looks up the IP address, and finds the MAC to be addressed to host 2. Then the router changes its source MAC to G0/1 and its destination to host 2? Cuz, I feel like you missed that step there. You said it goes from the router RIGHT to the destination host (while going through the switch as well).
This world needs teachers like you. You explain it in a fun way with an easy to understand non technical language. Thank You.
Dozens of videos…. This right here is El Dorado. Gifted TEACHERS are never compensated nor appreciated enough. Thank you.
This really helped me. I passed CCNA and work as a network engineer and still find myself thinking "Frame or packet??". This is really clear and helpful. Thank you. Just subscribed too.
Mate you've just helped me understand what my lecturer has been talking for 20 minutes in 7 minutes, cheers.
"Took the data put it into the packet, took the packet, put it into the frame" sir, thank you for a great explanation!
I’ve watched plenty of videos on this topic. For a newb such as myself, you hit on aspects that seem implied but not taught by others. This cleared up a lot of fuzzy knowledge I had. Super helpful.
beginning to think i should just toss my tuition to youtubers instead of my school.
right ? ...shhhhiiitt
Literally at my job right now looking at this stuff cause uni didn't teach me shit!
that is so funny! just so true. :-( Thanks tho!
Like my boss told me "college is for people who need to learn how to use TH-cam and Google."
Tell me about it!!! I am using Coursera right now and while it is good information, it is proving difficult to understand. I will definitely be using this youtuber to supplement my Certification Training.
finally i understood how the mac is used in combination with ip. Thank you very much.

It took me 5years to understand this. Thank you so much very informative
After searching for this exact explanation for days, I finally land on this video . Thankyou for the simple yet comprehensive approach. Now I just need to add in the protocols.
I have been searching for this for days! A simple but understandable explanation to cover the basics for people who are just learning. Thank you so much!
Excellent, definitely looking forward to explanations like this one about VPN IPSEC, GRE, thanks in advance!
This was the best explanation of how data moves. No professor, textbook, or expensive learning package on these training websites can do what you just did.
Wow i never saw a teacher like you , u are really great In India we dont thought this must clearly but u made my day really so happy to learn from you thanks buddy lots of love from India
Thank you for this!!!!! I loved it!! I'm a very visual learner and I couldn't understand this concept until I saw this. Thanks a mil for saving me and helping me understand my coursework!!
Same to you
I've traveled far to find a video that could help me better understand how packets work. Thank you for your efforts.
Cleared some fundamnetals...Especially the part at the router where the frame is changed but the packets remain same. Everything now falls into place. Thanks a million

Man this explanation is the best I've seen so far! Cisco should totally hire you :) ! Thanks! ! !
Hear me out with this analogy. I see this as me sending out a letter (packet), which in this case my computer IP is my address, and the recipient's IP is where the letter is addressed to.

this makes sense to me :-)

BRUUUH IF ID HAVE TO SEARCH FOR 2 DAYS IT WOULD ALREADY BE 1 DAY PAST EXAMS

Best networking knowledge with simple steps.......Thanks
This is awesome explanation,I'm getting ready for my network+ on the 30 August 2023 and this will come in handy..
Thanks Jacob. This explain how the switch and router works together to communicate. I am studying my materials for CCNA and the tutor just doesn’t mentioned the encapsulation and decapsulation of it.
Great video. Someone who can make it sound simple knows his staff.
most logical and correct explanation for this mind budging thing, hats off to you!
Thank you Jacob. You just defined this technology beautifully.
I've been looking for this all day. Graphics w explaining is EVERYTHING
I find this video most useful, it has explained all the concepts in a very simple way. Thank you so much for the efforts you have put to make this video!!

flying cats help
You should totally say: "from zero, to engineero".
FROM ZERO TO HERO IN TIME FLAT JUST LIKE THAT
@Ivy Yeah anyone that doesn't design, maintain or build engines isn't a real engineer! The English language never evolves to expand the scope of a term...
best explanation on frames and packets one could ever give!!!Thank You Sir You made my day. Love from India
Shouldn't each network have their own gateway?? Why is there only 1 gateway in this video.
Useful video. I particularly liked the way you explained how the data is encapsulated to a packet and to Frame... how the new frame is created at the router level.. Thanks for creating such videos.
Excellent explanation/demonstration for beginners! MUCH appreciated!
You have no idea how long I have searched for a video to explain this as clearly as this one has, Thanks! Clicking subscribe..
Wow! I had to watch this video more than once because data encapsulation was not just simplified but very fun to watch.
Very good and clear explaination! I can't look away when watching this! Good work!
Thanks for posting i am currently taking google IT course and there is a quiz on routing and subnet masks that is frankly confusing thanks for adding a little clarity .

SO USEFUL ! Thank you! You should be a lecturer!
Very well done man....I was confused on the default gateway until now!
Very beautiful explanation. Simple and easy to understand for a lame person.
My concept is clear about tcp/ip finally watching your video many many thanks
Perfect! This video is best explanation i've ever seen
Thanks for explaining this like a regular human being!
Waw ...nice explanation ....ur a super instructor .... thanks
That is one of the most easiest lesson I found over internet. Thanks bud.
Best video i have watched on this topic, thank you !!
love this guy! explains everything so well! easy to understand every time.
But there is one thing I don't understand : In this video the default gateway is in your house. But your gateway does not know the destination mac adress, yet in this video he says it does? I think only the router in the destinations network knows the final destination mac address??

Thank you Jacob, you explain complex, complicated things in most possible easy way. Greetings, flying cat.
I'm glad you said you are missing out the transport layer for simplicity! Good job.
Thank you loads for the help. You explain the whole thing simple and very clearly. I watched your other videos related to the IPV4 . They also same as this. Thank you again. Keep the good work up. 😁
Elama 😅
Best explanation ever! Thank you! continue the great work.
Thank you for your awesome illustration/explanation!
Awesome explanation sir. Got cleared most of the doubts in a single go
Thank you so much for making these videos!!!
really i enjoyed and learnt a thing which i dont know till date. i like ur teachng method............................

Can i just say no comments? Best networking tutorials ever for me. Ever!
PERFECTLY explained. thank you!!
That was a crystal clear explanation for me.. thanks a lot
Truly well-explained...
Thank you very much for making it easy to understand...
💯💯💯💯💯
you must be a genius, am trying to get ccent exams . you break everything down for me to understand. thanks alot. i had to even go and check if you guys offer thoses cause so i can take from you guys. will love to subscribe to your chenel for more studies

You are correct. That’s how it works.
That was a good explanation. Well done
YOu just earned a subscriber sir Good Job explaining it simply
This is totally wonderful. You the one!
Simplicity, better than CISCO videos ...Thank you
Thank you so much. Greatly appreciate all you do.
very nice and clear teaching. thanks!
If you can't explain it simply, you don't understand it well enough - Albert Einstein....I simply love this kind of explanation!
Your explanations are the best!! Thank you!!
That was so so good! Simplified for tech dummies and smarties too and still very fun and funny to watch. Thank you!
That is the best explanation that I ever had in my life.... thank you so much!!!
"Oh sweet, i got a frame"😂😂
What a great video! Thanks, man.
Your lessons are awesome! Great job explaining :)
thx, great video, im studyig for the final exam :)
This was so well explained! Thank you.
