I'm trying to comprehend how humans came together and created this. No matter how much I study technology it still feels like magic even though it is not.

I accidentally stumbled upon your and couldn't believe how good your content is!!! thank you

[Bing.Chillin]

I accidentally stumbled upon your channel today and couldn't believe how good your content is. Coincidentally I also love DIY electronics and programming so this video is just *chef's kiss*

[JohnThomas-ivlg]

One of the best videos ive came across explaining cpu, moms, and rams

[alexanderfeinberg]

Wow. This is better than any course I've taken. The visualizations are extremely helpful

[steriftes]

I thought this was like 5 or 7 minutes long so i can use this as reference whenever i got any presentation assignment. Then i saw the 27 minutes.. 🤣🤣. Anyway, good job Ron! I just woke up and making my cereal yet rightaway i already got the right video for me watching while eating 😆

[bvideoz]

Major Tom, is this you?
Your English is surprisingly amazing 😊
By the way this English version made even more sense to me than the russian one - which already was the best I could find on the Youtube

[DeveloperUnited]

I've been looking for a video to teach my son about how computers work, since he's just starting to learn programming. This is by far the best video I've found!

[nend]

This video needs more likes, the content is very good as well as the illustrations

[matheusdosreisbravim]

One of the bests videos about that subject that i've seen

[Isthisreal]

Major props! Your articulation is fantastic! Keep it up!!!

[captainkeyboard]

Your show makes me, as a keyboard specialist, continue to appreciate the technology of the microcomputer, like the one I use. 💙

[flywithusMSFS]

Holy shit. You just made me discover what Windows calculator can do. HOLY SHIT.

[Firat-tofo]

Incredible explanation ❤👏 Much respect!

[anbesawtech]

Brother, This is the most impressive video I have seen that explains how computers function.

[xXCOSMOSXx]

dude, you re so underrated, the best explanation for memory i ve ever seen so far❤

[zorro]

Xcellent presentation was able to understand most of it except how the cpu understands signals from input output and also the reset circuit and how it interacts with the cs port of ram

[Frisky]

Not sure how I found you but what a great explanation of the the microcontroller and external rom ram access. Thanks

[SaurinShah]

take a bow sir.. great explanation! entire course in one video.

[abdulgaffarmohammedshafee]

Accidently come across your Programme... & decided to continue as articulation fantastic. Thank you
But have to listen again on data transaction.
