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

[@adityaanupindi145]

Love the way you explain things clearly.. keep the good work.. 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*

[@Frisky0563]

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

[@BryanChance]

What a great explanation!! Thank you.

[@maxmcclure2360]

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

[@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 😆

[@b213videoz]

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 TH-cam

[@abdulgaffarmohammedshafee9333]

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

[@Firat-to9fo]

Incredible explanation ❤👏 Much respect!

[@zorro20010]

very INSIGHTFULL 4 a layman ...... not seen video about programming with electronics fundamentals with such CLARITY .... need to watch it several times 2 internalise the knowledge

[@marios2620]

Thank you very much! Your Seminars are Very helpful to mel! ,And I can understand your clear English speaking 👋

[@Binoyxxx9]

Accidentally came... cleared almost all doubts

[@tammip5497]

Great video and graphics! Thank you for this very enlightening explanation. I think it would be great if you can for example extend this to explain how C64 works (all different chips, etc)

[@Gaminiheraliyawala]

Fantastic presentation on how the computer is working. Thank you very much for the knowledge sharing. it was very comprehensive and soooo easy to understand. 🙏🙏🙏🙏👍👍👍👍💐💐💐💐

[@capfsb]

Its best video about this what i see, so clear explanation, thank you

[@arvinmistry9744]

It was great understanding microprocessor sequence, please if you can make more vidoes with simulation follow by arrow in input and output will be great.

[@user-ys5mz9hp4l]

very helpful ! thanks for sharing !

[@kishorek-uw3fy]

brilliant explaination

[@velikanskaglava2087]

Great video, should have more views!

[@lukhmanummer7838]

brother is really good, top quality content

[@harveykisiangani9939]

Really helpfulllll, thanks

[@Awcator]

The amount info this video contianed 😮👌

[@user-gs9ik4me9v]

thanksss alottt

[@OmNaidu-tt1df]

Hey
What u think happen if I make some kind pcb which has multi socket for two i3 processor and if I cam run the cpu does that make it faster ? Or it could just take single instruction and feed them into both and they both solving the same calculations?

[@AK-ig3ko]

👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏 no need words

[@uttamkumarsingh2465]

Is it 65536 bits or bytes ?? I guess it shall be 65536 bits.

[@uttamkumarsingh2465]

You are confused. Address bus is of 16 bits. Hence it can access 65536 memory location in the storage or memory device. Each location of the memory can store 1 byte of data, which means 65536 memory location can store 65536 bytes of data.

[@TheGrezly]

Byte

[@jj74qformerlyjailbreak3]

Where eas this video 25 years ago? Would have saved me tons of time. 😂😆

[@capfsb]

I would to know how input works and how interupt bus works

[@DonCuan491]

My Idiot brain can understand to this difficult lessons in myl life, oke thank you my bro for yours video.

[@Keks603_]

Finally a video that my smooth dumb brain can understand! 😁😁

[@wirechair]

Whoa! It's crazy that no one person on earth understands how a pc works! That's probably why AI is beyond our understanding now.

[@RS_83]

Thank you. Very informative video.

[@cristianluchian4907]

Thank you sire
