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.

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.

Dozens of videos…. This right here is El Dorado. Gifted TEACHERS are never compensated nor appreciated enough. Thank you.

"Took the data put it into the packet, took the packet, put it into the frame" sir, thank you for a great explanation!

[joshuacmorgan]

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.

You should totally say: "from zero, to engineero".

[jairusan]

Excellent, definitely looking forward to explanations like this one about VPN IPSEC, GRE, thanks in advance!

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 ☺️

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

[taniabaquera]

Thank you for 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!!

This is awesome explanation, I'm getting ready for my network+ on the 30 August 2023 and this will come in handy..

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.

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

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!

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

[tahersadeghi]

Thank you Jacob. You just defined this technology beautifully.

[chetan]

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.

[tatathebutterfly]

I've traveled far to find a video that could help me better understand how packets work. Thank you for your efforts.
