I’m glad I came across your channel. I work for Amazon overnight and decided to apply for their seasonal/ IT Associate Specialist role and they scheduled an interview with me!! 8/22… I have worked in tech, but not on the IT side. I was a Transport, Switch, NOC, NCC & field tech for years, now my aspirations have shifted to data. I have wanting to learn and have tangible IT skills for years - so here I am, a mom, techie, student at 53 ready to challenge myself further. To whoever’s reading this: life is gonna happen, excuses will creep in, but show yourself that you’re bigger than your fears and/or excuses - you’re ready - take action.❤

Going through this series wanting to make a career change. You're an awesome teacher. You probably won't see this but you definitely are doing amazing work. Thank you for taking the time to help us all out

[cherchil]

Dude i cant explain how much i am thankful for this series!

[bigdirtypj]

I just finished my Bachelor's Degree in IT and I am now studying for CCNA. Your videos are way more enjoyable than being glued to a book non-stop. Thank you for your effort in making these videos. Well done!

[Cerealbox]

I never knew how much I wanted to learn 10-20 minutes at a time every few days.

[drewuid]

These classes are more entertaining, digestible, and helpful than all of the the courses I've paid for. I feel like they just teach me about it and you somehow make me love it.

[myfriendjohn]

I always remembered it as: "Please Do Not Throw Sausage Pizza Away" I remember it from when I first learned the OSI years ago!

[benjaminwagner]

I love that Guy, his Mindset is pure motivation to start from scratch ! 🧔🧠❤

[gabrielreyes]

I remember the first letters of the OSI model with the phrase “A Priest Saw Two Nuns Doing Pushups”

Worked in IT for about 3 years now. Watched your "Starting over in IT" video a few days ago. Passed my AWS CCP but feel like I need better fundamentals in networking! Currently studying for my Network +. Love your channel and all your content. Thanks for bringing a modern and fun take on reaching networking. Graduated from college last December and my networking book was from 1997 and came with a floppy disk... needless to say we did not get taught very well!

[nerdynerdface]

I could hear the same concept 50 times, but when Chuck begins to describe the concepts, it just makes sense! Thank you for all you do. :)

When I first was studying networking in the mid 2000s I was taught the OSI model . To my understanding the TCP/IP model is the same except it merges the layers of the osi model so there are less in total. I find using the osi model great for troubleshooting as I feel I can see more and break things down more finely.

I'm so glad my teacher uses your videos to teach us. You're super easy to understand and you keep my attention somehow.



Also I love your beard

[miguelk]

Chuck I obtained my CCNA 1 week ago, thanks for all your great content and motivation!

[baileyholtzman]

Chuck,

I just discovered you. Completely rekindled my love for programming/ethical hacking/ etc. Thank you, thank you, THANK YOU!

[InfiniteLogins]

Really appreciate all of the effort you put into your videos Chuck. You inspire me to be a better teacher in my own!

[finskou]

Oh. My. God. I got my CCNA certificate end of December, but i think that was out of luck because I have to relearn it all (it was very clear). I'm SO SO happy to have found you and SO SO sad I didn't find you whilst studying my CCNA. I'm binging your videos this weekend. You are the teacher we all need. You explain things in such a good and easy way.. i mean, dayum. THANK YOU !
