Finally a networking video that shows the actual hardware, visuals are very helpful.

[yegeikosyn]

Even a retired 80 years old granny will pass the exam after watching your videos man ))) Thank you so much !

[unknownsilence]

This guy is more engaging than most of my college professors. He actually makes the stuff interesting. I also lost my shit when I saw Johnny and Lisa 😂

[calmhorizons]

Currently doing a CS course, and I learned more in this 20 min video than a 2 hour lecture. Great work.

Dude even if I get my CCNA I feel like I need a badass beard to be qaulified as a network engineer. Love this channel.

[WilliamHungVEVO]

Finally, I can get up off my lazy ass and focus on the CCNA, thanks NetworkChuck

[Ecliptt]

You make things so fun to watch and easy to understand with a little bit of humor, I'm def subscribing

[ussumaneembalo]

This guy doesn't just teach you, but he inspires you to become a network engineer. Thank you so much.

[alinjardas]

i love how you explain stuff...i bet you can make me fall in love with the most boring stuff out there.

[chinmaysharma]

I can't believe that this guy convinced me that some box that sits in a corner collecting dust in my school's computer lab is so amazing

[kevinm]

Chuck, you are the man! I love your passion and authenticity. Nice to see "young" people passionate about their craft these days. I'm a software developer with an interest in better understanding networking ... it's becoming more and more necessary as things move to the cloud.

[jashevan]

Thank you for your passion, attention to detail, and sensibility to simplify without compromising essentials. You are special. Please keep it up. You are helping change lives for the better. Rock’n roll brother.

[katlegobopape]

"PING!".... "REPLY!" 😅 that was actually helpful. Chuck makes learning so much fun. 👍 Nice one Chuck.

Man I hope you read this.
Last week some friends of my university enroll in a ccna course that I really wanted to. I love this topic, network and so. I'm a student from TEC Costa Rica. I can't pay a ccna course it was somehow frustrated and I realize that this course was available. Now I can say thank you for giving this opportunity (taking into consideration there is more to cover). You no have idea how happy this made me feel. I just want you to know that you are changing someone's life in a positive way. Never stop doing this things, and the day you made the choice of working more in your channel it was for a good reason. Keep going and thank you!!!

[magickpalms]

Chuck is such a good teacher... so many tutorials put me to sleep but he is so entertaining and informed that i watch them for fun and knowledge. Truly a blessing!

[Michaelscarn]

Thank you so much for existing.

I’m taking my first Cisco course in college and it’s so much reading. I learned so much and better in 20 mins from your video than studying a whole day.


I am now going to your videos after reading cause it helps bring everything together.


Thank you!!!

[alvaroreyes]

You’re awesome. I have ADHD and it’s hard as hell to follow along and focus most of the time but your videos are SO easy to follow along. Keep up the great work!

[devamalya]

Amazing work Chuck ! :)
Just a small add on. The way the switch learns the MAC for the first time is by forwarding the packet on all ports, except the one it came on. Only the intended recipient replies. Now the switch records the source MAC of the reply packet in the MAC Address table. Next time it knows which port to forward it on, since it is already recorded in the table.

[Joedymarz]

I just finished taking my first data and lans class for college and wow I am just amazed why I don’t find this channel earlier this is really engaging and really breaks it down for us normal people who are new to tech.

[NolanHill-cwjt]

So nice to actually learn something and feel engaged. Every other channel I come across is just someone reading off of a slideshow that, by the end of, I still haven't retained anything because nothing is explained. You are one in a million, Chuck. Thank you, dude.
