Dozens of videos…. This right here is El Dorado. Gifted TEACHERS are never compensated nor appreciated enough. Thank you.
This world needs teachers like you. You explain it in a fun way with an easy to understand non technical language. Thank You.
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.
Mate you've just helped me understand what my lecturer has been talking for 20 minutes in 7 minutes, cheers.
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.
"Took the data put it into the packet, took the packet, put it into the frame" sir, thank you for a great explanation!
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...
Excellent, definitely looking forward to explanations like this one about VPN IPSEC, GRE, thanks in advance!
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.
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
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
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.
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.
Thank you Jacob. You just defined this technology beautifully.
Excellent explanation/demonstration for beginners! MUCH appreciated!
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!!
Thank you for your awesome illustration/explanation!
Great video. Someone who can make it sound simple knows his staff.
Very good and clear explaination! I can't look away when watching this! Good work!
Wow! I had to watch this video more than once because data encapsulation was not just simplified but very fun to watch.
That is one of the most easiest lesson I found over internet. Thanks bud.
Best networking knowledge with simple steps.......Thanks
You have no idea how long I have searched for a video to explain this as clearly as this one has, Thanks! Clicking subscribe..
I'm glad you said you are missing out the transport layer for simplicity! Good job.
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 .
Waw ...nice explanation ....ur a super instructor .... thanks
I've traveled far to find a video that could help me better understand how packets work. Thank you for your efforts.
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.
this makes sense to me :-)
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.
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!
Brilliant Kudos to you Caliber
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.
this video opened my understanding on packes, thanks
Thank you so much. Greatly appreciate all you do.
Your explanations are the best!! Thank you!!
I loved this please do more!!!!!!!!!! Laughed at the end thank you so much!!!!!!!!!!
This is awesome explanation,I'm getting ready for my network+ on the 30 August 2023 and this will come in handy..
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
Your lessons are awesome! Great job explaining :)
Beautiful presentation
Fantastic video.. Best explanation 👏👏
Very well done man....I was confused on the default gateway until now!
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 ☺️
BRUUUH IF ID HAVE TO SEARCH FOR 2 DAYS IT WOULD ALREADY BE 1 DAY PAST EXAMS
I've been looking for this all day. Graphics w explaining is EVERYTHING
Thank you Jacob, you explain complex, complicated things in most possible easy way. Greetings, flying cat.
Awesome explanation sir. Got cleared most of the doubts in a single go
Best explanation ever! Thank you! continue the great work.
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!
very easy to understand. Thanks for your sharing!
very nice and clear teaching. thanks!
Thank you for the simple and clear explanation.
Thank you so much for making these videos!!!
PERFECTLY explained. thank you!!
Fantastic Explanation ,thank you very much
That was a good explanation. Well done
That was a good explination and simple. Thanks.
What a great video! Thanks, man.
Perfect! This video is best explanation i've ever seen
This is totally wonderful. You the one!
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
Best video i have watched on this topic, thank you !!
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 😅
Nice explanation
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.
My concept is clear about tcp/ip finally watching your video many many thanks
This was so well explained! Thank you.
This helped me sooo much. Thank you!!!
flying cats help
best explanation ever. Thank you a bunch.
SO USEFUL ! Thank you! You should be a lecturer!
Thank you for this amazing explanation : )
most logical and correct explanation for this mind budging thing, hats off to you!
Great explanation.. Thanks 👍
Amazing explanation.
really i enjoyed and learnt a thing which i dont know till date. i like ur teachng method............................
Superb. Thanks a ton.
That was a crystal clear explanation for me.. thanks a lot
That was so so good! Simplified for tech dummies and smarties too and still very fun and funny to watch. Thank you!
Very informativ and helpful.. :)
You explain it so well!! Thank you
Perfect explaination!
Cool video. Thanks!
You explained it very well and in a simple way. Love it.
Man this explanation is the best I've seen so far! Cisco should totally hire you :) ! 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.
Thanks a lot for the explanations. Awesome videos
Valueble information sir
Great explanation ❤
Very good representation and easily understood.
Nice explanation 👍
Great content 👍
Well done man perfectly explanation
amazing vid! This is as simple as it gets
Beautifully explained
Dude the best explanation ever!!!!!!!!!! .... thank you sir
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??
Wow, well done!
Very good explanation !
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
Thanks for explaining this like a regular human being!
Great video
